History WhatCouldHaveBeen / PrehistoricEarth

* Alice and Adrian were also initially intended to have a small amount of ShipTease between them, with the plan first being for them to be an outright OfficialCouple. Then this was later initially changed to have Adrian only have a single sided [[UnrequitedLove crush]] on Alice. Ultimately, Nathanoraptor decided to scrap this idea altogether when he realized that the plans weren't really working out and replaced the planned arc between Adrian and Alice with the WillTheyOrWontThey arc between Alice and Will. However, the idea of Adrian having a one-sided crush on Alice currently appears to be getting [[RefittedForSequel revisited for the subsequent reboot]] ''Fanfic/PrehistoricParkReimagined''.

* Returning to the continued subject of Cynthia, Luczynski wanted her to be the one to accompany Drew and Alice during ''Serpents of the Nile''. The way he saw it, due to how Phase 3 was intended to have a healthy focus on Alice's WillTheyOrWontThey RomanceArc with Will, having an already established OfficialCouple working together and accompanying her on this mission would help to add emphasis to the matter. Nathanoraptor vetoed this and had Leon accompany them instead as he believed that Leon would be much more empathetic, perceptive, and sensitive to romance related matters and Alice's situation compared to Drew (who often had a tendency to either be completely oblivious about other peoples' feelings or outright ignore them altogether) and Cynthia (who didn't really have any personal attachment to Will or Alice at that point in the story and thus would likely not really have cared that much about what was going on between them) as well as because Leon's planned RomanceArc with Yolanda and Alice's own WillTheyOrWontThey arc with Will, plus the added symmetry of the both of them having their love interests back at the park taking care of the orphaned baby leptictidium while they were on the mission, allowed them both to bond together and be more thematically appropriate in working together alongside Drew in the context of that particular mission.

* Luczynski originally wanted Drew to blatantly explain to Jack about euparkeria being believed to be a direct evolutionary ancestor to dinosaurs during ''Life and Death Promised''. Nathanoraptor, changed it to have Jack mention the fact write as Drew was working on mentioning it because Nathanoraptor felt that Jack would be in character to be smart enough to already know this information. Luczynski also originally wanted Jack's line before Leon's successfully distracting the therocephalians and leading them through the portal to be "[[WesternAnimation/TheLionKing What do you want us to do? Dress in drag and do the hula]]?'' Nathanoraptor changed this to "What do you want us to do? Douse ourselves in steak sauce and dress as a chew toy?" because he felt that this line would be much funnier (and more subtle), and the originally planned line was a little too much of a gratuitous (and pointless) ShoutOut.

* Leon was originally intended by Luczysnki to not have a very good start in his allosaur training. Specifically, the very first day of his allosaur training efforts was supposed to [[HumiliationConga constantly go wrong]], as a homage to Tadashi and Baymax in ''WesternAnimation/BigHero6''. Nathanoraptor, however, thought it dragged out the story. As a result, Leon's training of the allosaurs went much more relatively smoothly from the very beginning and was played entirely seriously. On a similar note, Luczynski also originally wanted all five of the young male allosaurus to be on the 'squad'. Nathanoraptor, however, felt that it would be more workable for only three of them to be on the squad, and so the squad was whittled down to [[Series/GameOfThrones Drogon, Viserion, and Rhaegal]].

* Sharptooth throwing a fit because of a medical problem was initially planned to occur in ''Serpents of the Nile''. Luczynski subsequently suggested for Nathanoraptor to agree to move it to ''The New Giants'' so that Sharptooth would have a chance at having more time to adequately show off his usual personality before any signs of his vulnerable side got shown off. That being said, the medical problem in question was originally planned to be a [[TheToothHurts toothache]]. But Nathanoraptor then changed his mind and changed it to [[AgonyOfTheFeet an in-grown claw on his foot]] when he realized that t-rexes constantly shed and regrow their teeth like crocodiles and sharks, and would thus realistically have very limited opportunity to develop a toothache.

** Von Grimm was initially not supposed to show up on the island in person. Instead, Frank and Duncan were to betray him by taking over the entire operation themselves, becoming the main antagonists. More specifically, ''Isle Full of Noise'' was initially planned (before all the changes that got made) to open with Duncan arriving at the smuggling operations' base in time to show the successfully stolen portal to Frank and Percival (the latter of whom would have been watching via video communications) before he and Frank would have then carried out their betrayal against von Grimm and taken full control over the smuggling operation themselves. However, Nathanoraptor eventually decided that it would be [[TheyWastedAPerfectlyGoodCharacter a wasted opportunity to not allow von Grimm the opportunity to have a face-to-face confrontation with the heroes]].

* Spiny the dimetrodon was originally intended to act like a dog for both RuleOfFunny and for the sake of promoting a separate fic. Nathanoraptor thought this would be too [[ItsTheSameNowItSucks cliche]] and unrealistic, and also believed that Spiny the way Luczynski planned him to be was both a blatant ripoff of [[WesternAnimation/TheFlintstones Dino]] and an embodiment of the AllAnimalsAreDogs cliche (a major pet peeve of his), and had Spiny (alongside the other dimetrodons) altered to behave more like a cat or tegu lizard instead. Luczynski was [[CreatorBacklash not pleased]] with this change. Furthermore, Nathanoraptor also initially planned for the scenes with Spiny, Lubbock the petrolacosaurus, and Howler the hynerpeton to play out more similarly to a Tweety and Sylvester short (with Spiny chasing Lubbock around the park ala Tweety and Sylvester, only for Spiny to end up encountering and getting scared off by Howler similarly to how the bulldog in Looney Tunes tended to do the same to Sylvester). Nathanoraptor also even planned for multiple other such shorts of a similar nature involving different newly rescued animals to occur over the course of the story. Luczynski, however, vetoed this idea for unexplained reasons and chose to have the scenes with the three critters in ''The New Rulers'' instead play out more like a Wile-E Coyote style scenario; something that he has probably forever regretted since due to how Spiny ended up having no more reason to be a prominently featured character as a result of his short-sighted vetoing of Nathanoraptor's idea. Furthermore, Nathanoraptor himself came to develop a [[CreatorBacklash scathing hatred]] of Spiny, Lubbock, and Howler's subplot due to his (in his mind) arguably superior idea getting shot down.

* There was originally going to be a line blatantly making clear the fact that someone had mysteriously deleted a message Drew had sent to Kyle and Nikolai during ''Degrees of Greatness''. Luczynski suggested that Nathanoraptor remove this line because it looked to unsubtle, and Nathanoraptor agreed that his co-writer had a point.

* Kaisumi Ishiara was initially intended to play a considerably larger role in the story. For undisclosed reasons, she was instead reduced to received only a silent cameo in a single brief scene in ''Spirits of the Silent Forest''.

* Drew was initially planned by Luczynski to openly mourn all the dinosaurs that had died in the KT event ([[IShouldHaveBeenBetter and that he therefore failed to save]]) over the course of his time marooned in the post KT event landscape. Nathanoraptor, however, convinced him to change this to Drew having difficulty fully comprehending the true scale of the disaster and all the deaths it had caused since [[RealityEnsues he felt that would be more realistic]]. In fact, several of the lines in Drew's mental thoughts on the matter during the scenes in question in the final product [[RealitySubtext were stuff that Nathanoraptor himself had said to Luczynski over the course of convincing him to go through with the change]].

** If the 'mainland' version of the climax had occurred, then the story would have ended with all the scenes already present in the final product, Percival's arrest being mentioned to have occurred off-screen, [[TheLastOfTheseIsNotLikeTheOthers and a scene with]] [[TheEndOrIsIt Scarface]] [[BreadEggsMilkSquick lurking about freely through the everglades]].

* As mentioned above, Jack wasn't originally planned to be the major character he ended up becoming. Rather, he and Alice were supposed to serve as supporting protagonists to work alongside the 'main trio' of Drew, Leon, and Adrian. This was also intended to be highlighted with Jack serving as little more than a comedy sidekick with a penchant for [[LamePun lame puns]]. However, a mixture of both Nathan and Luczynski noticing the unexpected level of depth they'd managed to give him alongside the planned penchant for puns, and difficulty in figuring out appropriate puns for Jack to have available for use in every subsequent mission led to them boosting his prominence as described above.

* As described below, Cynthia was originally only intended to be a RedHerring for the sabotage. When this was still going to be the case, the 'sabotaged lock' was originally intended to just be a result of the lock being faulty and in need of replacement. But when she was later changed into being a [[TheMole mole]], the faulty lock was likewise changed so that it had indeed been sabotaged by Duncan.

* Luczynski initially wanted Mia to be the one who ended up having to be rescued from the brontoscorpio, likely because this was intended to tie into his plan to have Nikolai release Hedetet into the tank to scare off the brontoscorpio in time for Leon to safely get her out to safety. Nathanoraptor, however, pointed out that it would make more sense for Yolanda to be the girl that Leon dove into the holding tank to save, as she was the one that he arguably had a much more personal connection with at that point, which would both increase the stakes and make Leon's subsequent first time [[TookALevelInBadass taking a level in badass]] more meaningful (not to mention the fact that it would also allow for a logical starting point for what would lead up to their planned RomanceArc later in the story). In the end, Luczynski realized that Nathan had brought up a valid point, and so they managed to [[TakeAThirdOption reach a compromise]] by having Yolanda be the one who fell into the tank and that Leon dove in to save, only for him and Mia both to end up needing help doing so via Nikolai releasing Hedetet into the tank with them right as they're about to be overwhelmed by the brontoscorpio swarm.

* Alice and Adrian were also initially planned (likely by Luczynski) to end up arriving in time to save Drew while Leon and Adrian were still arguing during ''Life in Transition''. Nathanoraptor scrapped this because he felt the idea was stupid and because Leon and Jack needed a proper incident to incite their eventual reconciliation and fire forged friendship.

* As described below, Cynthia was originally only intended to be a RedHerring for the sabotage. When this was still going to be the case, the 'sabotaged lock' was originally intended to just be a result of the lock being faulty and in need of replacement. But when she was later changed into being a ReverseMole, the faulty lock was likewise changed so that it had indeed been sabotaged by Duncan.

* Furthermore, Cynthia wasn't initially planned to turn out to be Theodore's spy working to expose von Grimm's mole. She was initially only planned to turn out to be a red herring. But Nathanoraptor eventually decided that only having her be a red herring for the identity of the von Grimm mole would be a bit too anticlimactic. And so she was made both a red herring AND a reverse mole working for Theodore to expose the true mole.
* That in mind, Luczynski also originally wanted for the reveal of Cynthia being Novum's ReverseMole instead of TheMole working for Von Grimm to occur immediately after von Grimm's reveal as the BigBad. Nathanoraptor had this reveal wait until the end of ''A Glorious Dawn'' instead so as to preserve the horror he wanted to be present for the reveal of Von Grimm as the big bad.

** Furthermore, Luczynski initially pushed for Cynthia to be made into a [[Deuteragonist secondary main character]], particularly for the sake of allowing her and Drew to be people to view Jack and Leon's (respectively) storylines through due to his then low faith in the characters' (especially Jack's) ability to carry a story (mostly due to him allegedly viewing the other characters as 'just side characters'). Nathanoraptor was not amused by this on account of how he had much more faith in Leon and Jack being able to carry a story on their own than his co-author did (particularly since he planned for the story to have more of an EnsembleCast style focus instead of the clean-cut protagonist surrounded by side characters focus that Luczynski had in mind), and in the end Nathanoraptor got his wish.

* PE!Drew was initially planned by writer!Drew to openly mourn all the dinosaurs that had died in the KT event ([[IShouldHaveBeenBetter and that he therefore failed to save]]) over the course of his time marooned in the post KT event landscape. Nathanoraptor, however, convinced him to change this to PE!Drew having difficulty fully comprehending the true scale of the disaster and all the deaths it had caused since [[RealityEnsues he felt that would be more realistic]]. In fact, several of the lines in PE!Drew's mental thoughts on the matter during the scenes in question in the final product were stuff that Nathanoraptor himself had said to writer!Drew over the course of convincing him to go through with the change.
* Cynthia's reunion scene with PE!Drew after his safe return wasn't initially included. Nathanoraptor himself chose to add it in for the sake of [[ThrowTheDogABone throwing writer!Drew a bone]].
* The ending of ''A Continent of Blight'' was initially planned by writer!Drew to lead immediately into the beginning of ''Nightmare Labyrinthine'', complete with a scene of an unseen figure walking into a control room and disabling the security measures for the theropod paddocks. Nathanoraptor convinced him to have the events of ''Nightmare Labyrinthine'' occur a week after ''Continent of Blight'' instead since he felt that it would be more realistic for PE!Drew to finally realize the unpleasant truth of his usual recklessness if he had sufficient time to fully process the fact after returning home from his temporary period of being marooned.
* Writer!Drew also initially planned for Sharptooth and Zira's conflict in ''Nightmare Labyrinthine'' to be more blatantly antagonistic and [[ItsPersonal personal]] in nature between the two of them, as well as for Sharptooth himself to be considerably more explicitly malevolent in nature. Nathanoraptor, however, felt that this anthropomorphized them too much and would be out of place amongst what had been established prior, and also wanted Sharptooth to be more similar to creatures like Godzilla[[note]]who are more the subject of simultaneous awe and fear rather than outright hatred[[/note]] and felt that having him be explicitly 'evil' in nature and personality made him seem too much like more of a HateSink instead, so these ideas got the ax. Leon riding on one of the allosaurus during the crisis was also considered, but ultimately axed as well due to Nathanoraptor deciding that it looked too silly in the context of what had been established. And even after Zira (and Keehar's) fight against Sharptooth was done and over with, Drew still wanted Sharptooth to continue to play an antagonistic role by actively seeking an opportunity for payback against Zira during phase 3. But Nathanoraptor felt it would be better for the story to have Sharptooth become a sort of AntiHero instead, and even went ahead and both created and set-up his idea for Sharptooth to form a bond with Yolanda for the sake of enforcing this decision. And furthermore, he also had Sharptooth largely avoid the other t-rex in the enclosure due to being more of an antisocial GrumpyOldMan.
* Writer!Drew also initially wanted the allosaurs and utahraptors to get into a fight against each other over the course of the chaos that ensued, only for Leon and Jack to intervene in time to get them to stop the fight. Nathanoraptor felt that the plot would be structured better to have Leon and Jack's 'taking charge' of their respective 'dino squads' occur at two separate scenes. However, he did appreciate the clear intention behind writer!Drew's original plans, so he added a scene where the Utahraptors save Jack from a predator that's trying to eat him, he and Red subsequently manage to get the pack to back off from attacking Nikolai and Collete, and Drogon, Rhaegal and Viserion try to attack Drew and Cynthia (not recognizing them) before being put in line by Leon.
* Nathanoraptor originally wanted the scenes with the giganotosaurus at Mesozoic Safaris to be preceded by scenes with PE!Drew ending up attacked and pursued by a panicked triceratops while in the midst of searching for the giganotosaurus and subsequently saved by Lightning before the argentinosaurus and a massive group of the other herbivores in the exhibit joined together and chased off the giganotosaurus after the carnivores' own arrival onto the scene. The intention behind this scene was for emphasizing Lightning having basically become the 'leader' of Mesozoic Safaris' inhabitants. For unexplained reasons, writer!Drew vetoed this version of the scenes.
* Writer!Drew was initially hesitant to have Cirrus be responsible for [[BigDamnHeroes saving Linda]] from the [[RaptorAttack velociraptors in the vet facility]] due to him thinking that Cirrus's HandicappedBadass state would put him at a disadvantage. Nathanoraptor, however, was able to convince him to let Cirrus remain the animal responsible for saving Linda since, realistically, even a wounded large pterosaur like Cirrus would still be more than capable of taking on two small velociraptors and winning.

* Writer!Drew also initially wanted the velociraptors and giganotosaurus (potentially amongst multiple other theropods) to be present at Main Street alongside Sharptooth immediately before Sharptooth's planned battle with Zira. Furthermore, he also initially planned for either PE!Drew or Cynthia to arrive on the scene with Lightning, all the other Mesozoic Safaris herbivores, and the Utahraptor and Allosaurus squads in time for them all to chase off all the hostile carnivores in the area that weren't Sharptooth.

* Nathanoraptor initially planned for Zira to pull a WoundedGazelleGambit against Sharptooth over the course of their fight in order to defeat him. He also initially planned for Keehar's DisneyDeath to occur before Zira was released by PE!Drew and brought in to take on Sharptooth. However, Nathanoraptor eventually realized that the scene needed a chance for a lull in which to focus properly on Keehar's seeming death (and possibly that, with such a lull in place, Zira's initially planned WoundedGazelleGambit might have ended up a bit redundant), and so Keehar's DisneyDeath was repositioned to occur while Zira was already actively involved in fighting against Sharptooth and her WoundedGazelleGambit got the ax.
* Writer!Drew wanted for Lightning to take part in the fight alongside Zira and Keehar, and also for the fight to end with Thanatos the liopleurodon lunging and snapping his jaws upon Sharptooth and bringing him down similarly to the mosasaurus doing so against the I-Rex in ''Film/JurassicWorld''. Nathanoraptor, however, felt that having Lightning actively participating in the battle would be too difficult to allow to unfold properly without either having Lightning's presence be pointless as a result of just watching from the sidelines, having Sharptooth come across as overpowered in the event of him being somehow capable of gaining the upper hand against Lightning despite the sauropod's superior size and earlier managing to subject the t-rex to TheWorfEffect in a previous encounter, or ending up ended too early and anticlimactically precisely because of Lightning's involvement. Eventually, a compromise was reached in that Lightning ended up serving the role initially planned for Thanatos by arriving in time to cause a lull in the fight just long enough for Jack to successfully tranquilize Sharptooth.

* That in mind, writer!Drew also originally wanted for the reveal of Cynthia being Novum's ReverseMole instead of TheMole working for Von Grimm to occur immediately after von Grimm's reveal as the BigBad. Nathanoraptor had this reveal wait until the end of ''A Glorious Dawn'' instead so as to preserve the horror he wanted to be present for the reveal of Von Grimm as the big bad.
* Nathanoraptor was initially uncertain as to whether he wanted the mother leptictidium to be killed by the gas. However, he eventually came around to writer!Drew's wishes for the mother leptictidium to die when he realized that the story needed a death in ''A Glorious Dawn'' for the sake of balancing out the SparedByTheAdaptation treatment that had been given to the baby gastornis and the adult male ambulocetus. He also figured it would be a good way to show just how powerful the gas cloud actually was.

* Returning to the continued subject of Cynthia, writer!Drew wanted her to be the one to accompany PE!Drew and Alice during ''Serpents of the Nile''. The way he saw it, due to how Phase 3 was intended to have a healthy focus on Alice's WillTheyOrWontThey RomanceArc with Will, having an already established OfficialCouple working together and accompanying her on this mission would help to add emphasis to the matter. Nathanoraptor vetoed this and had Leon accompany them instead as he believed that Leon would be much more empathetic, perceptive, and sensitive to romance related matters and Alice's situation compared to PE!Drew (who often had a tendency to either be completely oblivious about other peoples' feelings or outright ignore them altogether) and Cynthia (who didn't really have any personal attachment to Will or Alice at that point in the story and thus would likely not really have cared that much about what was going on between them) as well as because Leon's planned RomanceArc with Yolanda and Alice's own WillTheyOrWontThey arc with Will, plus the added symmetry of the both of them having their love interests back at the park taking care of the orphaned baby leptictidium while they were on the mission, allowed them both to bond together and be more thematically appropriate in working together alongside Drew in the context of that particular mission.
* Jack and Cynthia's rivalry wasn't initially planned, but ended up getting written in by Nathanoraptor completely by accident, [[ThrowItIn and subsequently allowed to stay in]] since he felt that it would make sense for Cynthia to still not necessarily like Jack that much for other reasons despite no longer considering him the prime suspect for being TheMole.
* Mammal Trail was originally intended to be called Mammal Mania. Writer!Drew himself chose to change the name when he realized how silly the originally planned name sounded.

* Sharptooth throwing a fit because of a medical problem was initially planned to occur in ''Serpents of the Nile''. Writer!Drew subsequently suggested for Nathanoraptor to agree to move it to ''The New Giants'' so that Sharptooth would have a chance at having more time to adequately show off his personality before any signs of his vulnerable side got shown off. That being said, the medical problem in question was originally planned to be a [[TheToothHurts toothache]]. But Nathanoraptor then changed his mind and changed it to [[AgonyOfTheFeet an in-grown claw on his foot]] when he realized that t-rexes constantly shed and regrow their teeth like crocodiles and sharks, and would thus realistically have very limited opportunity to develop a toothache.

* Raksha was initially planned to be a male (and have an unrevealed male sounding name), before writer!Drew convinced him to let the amphicyon be a female instead (complete with this suggestion allowing Nathanoraptor to decide on the name 'Raksha' in the first place). Nathanoraptor also initially planned for Raksha to be orphaned by means of her parents being killed by a hyaenodon. Writer!Drew, however, suggested that the orphaning be a result of a mudslide instead, which Nathanoraptor ended up going with in the final product.

* Zira was initially planned by writer!Drew to play a role in saving the team from the megalodon in ''Beyond the Sea'' by virtue of the portal ending up opened in time for her [[GiantFootOfStomping foot]] to come through it and stomp down on the Ancient Mariner's deck in time to throw off the sharks. This ended up changed once writer!Drew realized that it was proving difficult to make such an idea actually work without [[{{Narm}} coming across as silly]].
* The idea of PE!Drew using basilosaurus recordings to distract the adult megalodon wasn't initially planned, but ended up added in by Nathanoraptor when he realized that a large number of the missions had included one ChekhovsGun after another, and decided that it wouldn't hurt to make the basilosaurus vocals serve as yet another one.
* The megatherium Leon encounters during his solo mission in ''Ten to Midnight'' was originally going to be the scrapped smilodon antagonist Scarface (described in further detail below), who would have ended up running off into the undergrowth after the encounter was over. And with that being the case, he was also initially intended to be seen doing battle with (and subsequently getting defeated by) Diego before the bushfire came about. And during the bushfire, he would have managed to get through the portal without Leon noticing and gone rushing off into the wild surrounding the park without anyone else noticing afterward while they were all distracted by the mass group of animals PE!Drew and his team had brought back. And naturally, TheStinger would have featured a scene in which he was found and captured by the smuggling operation, setting up for his initial planned role in ''The Devils Here'' and ''Isle Full of Noise'' (see below for further information on said role). However, when Scarface ended up scrapped, Nathanoraptor still wanted Leon to encounter ''something'' in the forest during his solo mission in ''Ten to Midnight'', so he allowed Scarface to be replaced with the megatherium that Leon encounters in the final product while outright deleting and changing all the other scenes that would have featured Scarface as needed.
* Frank didn't exist at all in the original plans, and von Grimm was initially planned to play the more active antagonistic role in the climactic scenes in ''Isle Full of Noise'' instead. However, Nathanoraptor kept hitting walls trying to write von Grimm taking part actively in the events of the chapter without him coming across in a way that felt to Nathanoraptor as if he were undergoing VillainDecay[[note]]via somehow always losing his aura of enigma, mystery, and fear and ending up seeming not as threatening as a result[[/note]]. Then he remembered how writer!Drew had originally wanted him to have a bodyguard with him in ''The New Rulers'', and so he took the initially discarded bodyguard for von Grimm and turned him into Frank as seen in the final product.
* Writer!Drew wanted Cynthia to accompany PE!Drew during ''Full Fathom Five'', only for this suggestion to be vetoed by Nathanoraptor in favor of Leon due to Leon having developed the most alongside PE!Drew over the course of the story and arguably being the consistent true deuteragonist of the story (despite writer!Drew's efforts to push Cynthia into this role instead), as well as the fact that Nathanoraptor found PE!Drew and Leon to be a lot more fun to write together. Furthermore, Nathanoraptor also felt obligated to allow a followup on how Leon had noticed Alice talking to Cynthia on the communicator near the end of ''Ten to Midnight'' and found reason to feel suspicious, and having Leon accompany Drew seemed like a good way to do so.

* Writer!Drew initially wanted members of the smuggling operation to turn out to have been responsible for injuring Martha. Nathanoraptor initially seriously considered allowing this to be the case before eventually deciding against it when he realized that this would potentially be too obvious of a hint to the Prehistoric Earth staff at what was going on.

** Writer!Drew initially planned for it all to just be relegated to a side plot during ''Ten to Midnight'', with von Grimm having several moles in the park, who would be killed and eaten by Sharptooth, Zira, and other carnivores while Percival himself would be crushed to death in a building trampled by the herbivores (the fate that ended up befalling Frank in the final product). And all without anyone even being aware of the smuggling operation or anything untoward at all. The reason for this was because writer!Drew wanted for the animals to be responsible for defeating the human villains as a means of poetic justice. Nathanoraptor, however, felt it would be too anticlimactic to have the bad guys [[DroppedABridgeOnHim so abruptly killed off in one of the missions prior to the finale]] [[AntiClimaxBoss after having been so strongly built up prior]].

** All the action involving the smuggling operation in ''Isle Full of Noise'' was initially planned by Nathanoraptor to take place on a separate island, with Jack releasing all the animals amongst the cargo and their escaping into the wild on the island. He'd also initially considered having the action take place at a top secret Novum facility on the mainland before changing his mind to try to have it on another island instead. Writer!Drew, however, felt that it would be too confusing to have the action switching back and forth between two islands; Nathanoraptor agreed, and the second island was removed. Writer!Drew also pointed out that it wouldn't really work out to allow the animals amongst the smuggling operation cargo to escape into the wild due to the vast majority of them either being malnourished or having conditions that would prevent them from surviving very long (if at all) in the wild, resulting in the animals amongst the smuggling operation instead getting proper medical care and placed amongst the park's repertoire of animals on display.

*** Will, Alice, and Raksha were initially planned to end up locked outside of the 'main building' of the smuggling operation as a result of Frank initiating a lock-down. PE!Drew and Nikolai were initially going to be separated from Leon and Cynthia and end up being the only members of the group to end up face to face with Frank. Jack, Collete, Adrian, and Keehar, in contrast, were always intended to go onto the boat and end up held at gunpoint by a group of goons onboard as they do in the final product. That in mind, the cliffhanger was originally intended to end with Jack, Colette, Adrian, and Keehar as they ended up in the final product, Leon and Cynthia locked in the animal holding room inside the 'main building' alongside a large amount of captive animals, Drew and Nikolai being held at gunpoint by Frank, and Alice, Will, and Raksha being stuck outside the main building and at risk of being attacked by Scarface the smilodon (who would have been running lose in the area as a result of having snuck onto the boat that Duncan would have used to reach the area himself, and also would have been deliberately going after Alice for the sake of attempting to get revenge against her; [[RealityIsUnrealistic something that real big cats have actually done]]).
*** Subsequently, Jack was initially going to trick one of the more idiotic mooks into calling Keehar a dinosaur within earshot of the pterosaur (this was before the plan for this being Keehar's BerserkButton got scrapped), causing Keehar's resulting fit of rage to distract all the mooks long enough for Jack himself to get ahold of the remote that he then used to release the captive animals in the area the way he does in the final product, all of which would have killed the mooks while he himself, plus Colette and Adrian, would have then ganged up on and taken down the boat's captain. Alice, Will, and Raksha would have been saved from Scarface by Baloo once again (with help from Raksha). And Cynthia and Leon would have managed to escape from the animal holding chamber in time to come bursting into the scene with the allosaurs in time to save PE!Drew and Nikolai. From there, the allosaurs would have killed all but Frank, who would have willingly surrendered in these versions of the events, and Duncan, who would have escaped from the area, gotten into a jeep or boat, and tried to escape from the base with the inferior jury rigged portal. Unfortunately for him, Scarface would have ended up in the same jeep or boat as him, and would have then [[KilledOffscreen killed him offscreen]] in a GoryDiscretionShot before then leaving the subsequently crashed vehicle and gone rushing off into the wild, crushing the inferior jury rigged portal under his paw in the process.

* If Nathanoraptor had gone through with his original plans involving Cynthia and PE!Drew having previously been a couple prior to Cynthia's introduction in this story (which he ended up still considering canon to some degree despite never actively going through with making the idea explicit in the story), then her and Drew's breakup and turning into AmicableExes at the end of the story would have had extra weight behind it. Furthermore, the entirety of their relationship in the story would have gone as follows:

* On a particularly big note, writer!Drew initially envisioned this story to focus more on just simply adventuring in the past and actually caring for the animals similarly to an Animal Planet behind the scenes at a zoo show. [[CreativeDifferences Nathanoraptor, however, had other plans]], and he eventually won out and took the story in a completely different direction from what writer!Drew had envisioned. This particular glaring case of CreativeDifferences (and one where Nathanoraptor won out instead of him), plus the fact that the overwhelming majority of the readers seemed to be siding with Nathanoraptor over him, proved a heavy contributing factor to writer!Drew himself eventually developing CreatorsApathy for the story and allowing Nathanoraptor to do the majority of the work on it (even going so far as to willingly have minimal involvement in the writing for Phase 3) while devoting more of his own time to his passion project Dinosaur King Retold.
* On a lesser note, Jack and Alice would've eventually been revealed to have been orphans, with Alice planning to prove herself capable of handling things on her own and Jack's eccentricities receiving a FreudianExcuse. Nathanoraptor decided to remove this, as it didn't really have an effect on the plot, not every character really needed to have a tragic backstory to explain their issues, and Alice's desire to prove herself that writer!Drew wanted her to have didn't make sense due to her having already worked with plenty of dangerous modern-day animals prior to her work at Prehistoric Earth; also, it transpired that writer!Drew had gotten their ages the wrong way around.
* Some of writer!Drew's other ideas that ended up cut include Lightning and Zira forming an [[OddFriendship odd]] InterspeciesFriendship, Martha having a form of PTSD, and a smilodon named Simba killing one of the other rescued smilodons in a very gruesome fashion.

* Alice was initially planned by writer!Drew to be accompanied by PE!Drew when she went diving under the ocean during ''The Cruel Sea''. However, due to a miscommunication, plus Nathanoraptor's unwillingness to try to edit something too often after its already posted and the fact he believed that the scene as it ended up accidentally turning out [[RuleOfDrama helped increase the tension]], Alice ended up going down under the water alone. The lost communicator in that same mission was also originally intended to be the work of the mole; but then Nathanoraptor chose to instead have this be a rare case of the communicator genuinely ending up accidentally misplaced due to Duncan having never had the chance to be on the Ancient Mariner and steal the communicator that got lost.
* Writer!Drew also initially wanted Thanatos to be at least twice as big as he ultimately ended up in this story, if not twice the size he was in the original ''Series/WalkingWithDinosaurs'' episode he appeared in. He conceded with grace not to go through with this idea, however, when Nathanoraptor pointed out that such a massive size simply wasn't workable for the animal. Furthermore, Thanatos was also originally intended to have a much more prominent role in the story, but ended up getting DemotedToExtra instead when Nathanoraptor realized that, if Thanatos had gotten the prominent role originally planned for him, Drew would have ended up looking too much like TheAce as a result of him also having already bonded with the similarly massive and powerful Zira the T-rex and Lightning the Argentinosaurus (who himself was also initially intended to have a more prominent role than he ultimately ended up having in the final product).
* Writer!Drew originally wanted the male postosuchus to be named Kenge, after the male monitor lizard from ''WesternAnimation/TheLionGuard''. Nathanoraptor vetoed this idea due to it leaving no immediate corresponding appropriate name available for the female, and so the two ended up named Rojo and Rosa instead.
* During the scene immediately before Leon finally shows off his progress in training the allosaurus squad in ''The Cruel Sea'', Jack was initially supposed to tell off Cynthia for her lack of faith by saying "Just give him a [[PrecisionFStrike fucking]] chance, alright?!" Writer!Drew, however, forced Nathanoraptor to tone this rebuttal down due to him feeling that it was too uncharacteristically mean for Jack to say.
* There was initially consideration during ''Age of Giants'' for Adrian, Jack, and Alice to be turned into a 'B Squadron' for the rescue team while Leon, Cynthia, and PE!Drew served as the obvious 'A Squadron'. But Nathanoraptor eventually chose to drop this idea due to a then upcoming lack of ''all hands on deck' style missions for the rescue team as well as their not truly being a need for the rescue team to be split into A and B squadrons.
* Speaking of which, writer!Drew also originally wanted Drew and Leon to be teamed up with Adrian and Cynthia to be teamed up with Jack and Alice. Nathanoraptor had Adrian and Cynthia switch places because he felt the dialogue that would result from this arrangement would feel less forced and more natural, and also because he didn't believe that writer!Drew's initial plans for Cynthia in this mission made enough sense in regard to a specific planned plot point.
* Writer!Drew also wanted for Leon to encounter a flock of pteranodons and bring them through the portal during ''Age of Giants''. Nathanoraptor vetoed this idea due to the environment and time the team was in during this 'episode' not being appropriate for pteranodons to appear in and also because he felt that Leon not accomplishing very much would make his anxieties more justified and meaningful. Writer!Drew also originally wanted for Cynthia to be the one to go on the hang-glider and for her to successfully rescue the argentinosaurus herd as well as a flock of pteranodons on first try. Nathanoraptor vetoed this as well since he felt that the argentinosaurus being so swiftly rescued would have downplayed the planned sense of tension and drama that was planned by virtue of the team staying to protect the injured Lightning from the nearby pack of giganotosaurus and also because he felt that having Cynthia do all the awesome rescue work would only reinforce Leon's earlier status as TheLoad as well as make it look as if his anxieties in that regard were based entirely upon Cynthia instead of really being more of a general insecurity of his.

* Writer!Drew wanted there to be a blatant followup on the fate of the injured macrogryphosaurus from ''Age of Giants'' to be present in ''Feathered Dragons''. Nathanoraptor vetoed this idea due to both the macrogryphosaurus never being intended to play a major role as well as how, since the scene that writer!Drew had wanted it to appear in was in the context of an informal visit to the vets from Jack and Adrian to check on the already hospitalized Cirrus and Keehar, it wouldn't make sense for them to visit the macrogryphosaurus due to the dinosaur in question not having any personal connection to them that would justify their visiting it.

* Writer!Drew initially wanted the microraptor flock rescued in ''Feathered Dragons'' to be explicitly kept in the same enclosure as the borealosaurus. He later willingly chose to scrap this idea himself when he realized that, logically speaking, there was no way for an enclosure to be designed that would both allow the borealosaurus to have enough space to account for their massive size and still not allow the microraptor the chance to go flying right out of the exhibit.

* Writer!Drew initially wanted Red to start out as the runt of the Utahraptor pack and later become the alpha after a clash with the raptor that he himself wanted to be the alpha. For some reason or other, he ended up conceding to Nathanoraptor's wishes for Red to be the pack's alpha from the very beginning.
* Writer!Drew also initially wanted Koolasuchus to be present in a scene in which various herbivores and carnivores gathered together near the rescue team's campfire to keep warm from the cold during ''Spirits of the Silent Forest'', but allowed them to be replaced with steropodon instead after Nathanoraptor pointed out that, as amphibians, koolasuchus would be more likely to stick to moist environments and avoid the overly dry conditions that would result from the heat of the campfire.

* Writer!Drew initially wanted to wait until phase 3 before resolving the plot point of Balerion adopting the orphaned baby allosaurus hatchlings. Nathanoraptor, however, felt that [[FridgeLogic it made no sense for the park staff to wait so many months after their rescue to resolve the issue]], the fact that there was a six-month in-universe hiatus planned to unfold between ''Nightmare Labyrinthine'' and ''A Glorious Dawn'' would have only strengthened the FridgeLogic of the idea, and because he wanted Balerion to be able to do battle with Sharptooth during ''Nightmare Labyrinthine'' and felt that [[MamaBear parental aggression channeled for the sake of protecting offspring]] would be the perfect reason to allow such a fight to be capable of happening. And in the end, writer!Drew conceded to Nathanoraptor's wishes.
* The rescued mononykus were originally planned to live in Mesozoic Safaris alongside the various other herbivorous dinosaurs (that weren't the borealosaurus). This was changed when writer!Drew and Nathanoraptor realized both that the mononykus diet would potentially lead to complications regarding their living with the other herbivores in that area and that it would also be perfectly sensible for them to start living in the paddock that had originally belonged to the now adopted baby allosaurus group instead.
* The variation of a joke from ''WesternAnimation/{{Dinosaur}}'' that appears in ''Storm in the Desert'' was changed to the way it is in the final product as a result of how Nathanoraptor felt that the way writer!Drew initially wanted it to unfold resulting in a lame punchline that didn't quite fully make sense in context and also had a different line in mind for usage that he believed would be a lot funnier. That in mind, writer!Drew initially intended for the joke to go something like this:

* It had been Writer!Drew's idea to have Keehar accompany Adrian on every mission he was in - however, Nathanoraptor gave the ultimatum that Keehar would only accompany Adrian if he could play a meaningful role, rather than just "sitting in the background, squawking". In accordance with the ultimatum, Keehar does not accompany Adrian on any of the four missions he goes on in Phase Three.

* Writer!Drew initially wanted Cynthia to take charge while PE!Drew was marooned in the post KT Event Cretaceous landscape. Nathanoraptor had Jack fill this role instead since this particular moment in the story felt like the perfect point to have a natural conclusion to Jack's arc of [[TookALevelInBadass shifting from]] ButtMonkey to [[TheLancer competent second in command and occasional acting leader for the rescue team]].
* Writer!Drew also initially planned for one of the other team members (possibly Leon) to accompany PE!Drew to the t-rex nest and end up heroically pushed through the portal by him seconds before PE!Drew's ending up marooned. This was changed to PE!Drew going to the rex nest alone due to a mixture of writer!Drew realizing that the way he originally planned for the subsequent scenes to unfold was starting to over complicate matters and Nathanoraptor wanting PE!Drew's marooning to be entirely his own fault and have no heroic, brave, or self-sacrificial overtones to it for the sake of the planned arc he had for the character.

* The story in its current form very nearly didn't exist at all! In fact, due to initially only being able to access Fanfiction.net on his phone (on which he was unable to use the website's 'publishing' features), writer!Drew initially was willing to make do by posting the chapters in the review section of another pre-existing story. He managed to utilize this planned posting strategy for an early version of the prologue (which was entitled "More than Just a Couple Pandas" and seemingly described Theodore as a black man instead of the white man he became in the final product) before he later teamed up with Nathanoraptor. He also managed to get ahold of a computer (or similar device on which he could access the website's publishing features) in time for his later fanfiction work.
* The two instances where Nikolai is referred to (and annoyed) by the nickname 'Koli' by Kyle were originally intended to be the first two instances of a running gag that writer!Drew had come up with. Nathanoraptor, however, had it scrapped after only those two aforementioned instances since he [[ItMakesJustAsMuchSenseInContext had no idea why the nickname would be so annoying to Nikolai]] and also believed that Nikolai worked much better as the straight man reacting to the antics of the explicitly goofier characters than as the butt of a joke himself.

* During ''New Beginnings'', the initial plan for rescuing one of the anomalocaris involved PE!Drew blatantly ''pushing'' Leon into colliding against the anomalocaris, at which point he and the anomalocaris would have both ended up sent through the portal. Leon was also originally planned by writer!Drew to be TheVoiceless all the way until the very next mission, ''Devils of the Deep'' (with what was then intended to be his very first ever line in the whole story being designed to serve as a LampshadeHanging for this prior status). Nathanoraptor changed this to be the way it is in the final product since, in his eyes, writer!Drew's initial plans didn't really work that well or properly do Leon justice.

* Nathanoraptor also originally planned for [[CoolBoat the Ancient Mariner]] to have its introduction in ''Devils of the Deep''. If that had happened, then the scenes with the cameroceras would have involved the orthocones in question first finding the planned bait sent down from the boat in the middle of the water (complete with one of the tentacles getting caught on camera gripping the bait in a 'found footage style' scene) before then engaging in a kraken-style attack against the ship. But Nathan himself eventually chose to scrap the planned introduction of the ship when he realized how impractical its use would be in the Ordovician period due to the how unlivable the Earth's atmosphere was for anything above the water's surface during that time period.
* Writer!Drew initially wasn't entirely certain that Jack would be interesting enough to carry a story on his own. Nathanoraptor, on the other hand, had enough faith in the character's ability to carry a story to convince writer!Drew to give him a chance.
** To writer!Drew's credit though, Jack was also initially not planned to take the major role that he ended up taking. The initial 'leading trio' was originally intended to be PE!Drew, Leon, and Adrian (due to them being written as close friends). But later on, after Jack's dialogue in "The First Steps" was written, the authors soon came to realize that Jack was a lot more interesting than Adrian. And as a result, Jack ended up getting his prominence in the story significantly boosted while Adrian ended up becoming immensely OutOfFocus throughout multiple parts of the story.
** Furthermore, writer!Drew initially pushed for Cynthia to be made into a [[SpotlightStealingSquad secondary main character]], particularly for the sake of allowing her and PE!Drew to be people to view Jack and Leon's (respectively) storylines through due to his then low faith in the characters' (especially Jack's) ability to carry a story (mostly due to him viewing the other characters as 'just side characters'). Nathanoraptor was not amused by this on account of how he had much more faith in Leon and Jack being able to carry a story on their own than his co-author did (particularly since he planned for the story to have more of an EnsembleCast style focus instead of the clean-cut protagonist surrounded by side characters focus that writer!Drew had in mind), and in the end Nathanoraptor got his wish.
* As mentioned above, Jack wasn't originally planned to be the major character he ended up becoming. Rather, he and Alice were supposed to serve as supporting protagonists to work alongside the 'main trio' of PE!Drew, Leon, and Adrian. This was also intended to be highlighted with Jack serving as little more than a comedy sidekick with a penchant for [[LamePun lame puns]]. However, a mixture of both Nathan and writer!Drew noticing the unexpected level of depth they'd managed to give him alongside the planned penchant for puns, and difficulty in figuring out appropriate puns for Jack to have available for use in every subsequent mission led to them boosting his prominence as described above.

* Writer!Drew initially wanted Mia to be the one who ended up having to be rescued from the brontoscorpio, likely because this was intended to tie into his plan to have Nikolai release Hedetet into the tank to scare off the brontoscorpio in time for Leon to safely get her out to safety. Nathanoraptor, however, pointed out that it would make more sense for Yolanda to be the girl that Leon dove into the holding tank to save, as she was the one that he arguably had a much more personal connection with at that point, which would both increase the stakes and make Leon's subsequent first time [[TookALevelInBadass taking a level in badass]] more meaningful (not to mention the fact that it would also allow for a logical starting point for what would lead up to their planned RomanceArc later in the story). In the end, Drew realized that Nathan had brought up a valid point, and so they managed to [[TakeAThirdOption reach a compromise]] by having Yolanda be the one who fell into the tank and that Leon dove in to save, only for him and Mia both to end up needing help doing so via Nikolai releasing Hedetet into the tank with them right as they're about to be overwhelmed by the brontoscorpio swarm.
* Nikolai and Kyle were initially planned to have a brief rivalry during the earlier sections of the story. Due to how there ended up being [[FourLinesAllWaiting too many different arcs to juggle over the course of phase 2]], this idea ended up falling by the wayside (before eventually being [[RefittedForSequel repurposed for the subsequent reboot]] ''Fanfic/PrehistoricParkReimagined''.
* Theodore was also originally planned to physically appear at the park at the end of ''The First Steps'' (and potentially of EVERY mission entirely) for the sake of giving hints for every mission set to follow. For reasons unknown[[note]] although Nathanoraptor suspects that it was either a result of him and Drew considering it too repetitive to constantly have him appear at the end of every episode or them thinking it would ultimately prove [[ViewersAreMorons too insulting to the readers' intelligence]] [[/note]], this was scrapped.
* Alice and Adrian were also initially planned (likely by writer!Drew) to end up arriving in time to save PE!Drew while Leon and Adrian were still arguing during ''Life in Transition''. Nathanoraptor scrapped this because he felt the idea was stupid and because Leon and Jack needed a proper incident to incite their eventual reconciliation and fire forged friendship.

* Nathanoraptor wanted to call the mesothelae spider megalorachne, but he and Drew eventually decided to just call them mesothelus in this story for the sake of simplicity. On a similar note, Pumpkin was originally planned by Nathanoraptor to be named Neith (after the Egyptian goddess of the hunt) as suggested by Flameal15K when the spider was planned to be the animal partner for a character Flameal15K had suggested for inclusion in Prehistoric Earth. Drew, however, made her be named Pumpkin instead (after a character from one his favorite anime, ''Anime/AkameGaKill'').

* Speaking of Colette and Nikolai, the scene where Colette, Jack, and Leon get comically 'attacked' by Pumpkin was originally intended to both only involve Colette getting 'attacked' and be more karmic in nature against her. Specifically, writer!Drew had wanted her to blatantly startle a keeper handling the arthropods into accidentally getting himself cornered by them simply [[ItAmusedMe for shits and giggles]] before Nikolai stepped in and stared the arthropods down into submission as he does in the final product, followed by Pumpkin jumping upon Colette and sending her running out of the Carboniferous bug house screaming in fright. Nathanoraptor changed this to its current form in the final product because, in his eyes, this would have been a 2nd time that writer!Drew had tried to turn her into the resident bitch when she was explicitly supposed to be the resident ActionGirl instead (while also being a JerkWithAHeartOfGold at the very worst).
* Spiny the dimetrodon was originally intended to act like a dog for both RuleOfFunny and for the sake of promoting a separate fic. Nathanoraptor thought this would be too [[ItsTheSameNowItSucks cliche]] and unrealistic, and also believed that Spiny the way writer!Drew planned him to be was both a blatant ripoff of [[WesternAnimation/TheFlintstones Dino]] and an embodiment of the AllAnimalsAreDogs cliche (a major pet peeve of his), and had Spiny (alongside the other dimetrodons) altered to behave more like a cat or tegu lizard instead. Drew was [[CreatorBacklash not pleased]] with this change. Furthermore, Nathanoraptor also initially planned for the scenes with Spiny, Lubbock the petrolacosaurus, and Howler the hynerpeton to play out more similarly to a Tweety and Sylvester short (with Spiny chasing Lubbock around the park ala Tweety and Sylvester, only for Spiny to end up encountering and getting scared off by Howler similarly to how the bulldog in Looney Tunes tended to do the same to Sylvester). Nathanoraptor also even planned for multiple other such shorts of a similar nature involving different newly rescued animals to occur over the course of the story. Writer!Drew, however, vetoed this idea for unexplained reasons and chose to have the scenes with the three critters in ''The New Rulers'' instead play out more like a Wile-E Coyote style scenario; something that he has probably forever regretted since due to how Spiny ended up having no more reason to be a prominently featured character as a result of his short-sighted vetoing of Nathanoraptor's idea. Furthermore, Nathanoraptor himself came to develop a [[CreatorBacklash scathing hatred]] of Spiny, Lubbock, and Howler's subplot due to his arguably superior idea getting shot down.

* Furthermore, PE!Drew's angst over failing to save the mother dimetrodon that got killed would have been considerably more prominent, and he would have been cheered up and reassured by Cynthia in a way that would have led to a reportedly immensely unsubtle moment of ShipTease. Nathanoraptor, however, didn't like how {{Anvilicious}} the planned moment of ShipTease was and also felt that PE!Drew's angst as writer!Drew had planned it to be came across too much as {{Wangst}}, so the ShipTease was removed, the angst was downplayed, and more focus was placed on the injured mother dimetrodon's recovery and the dead mother dimetrodon's eggs hatching.
* Percival von Grimm initially didn't even exist in the story. More specifically, writer!Drew initially planned for ''Theodore'' ([[BigGood of all people]]) to turn out to be EvilAllAlong and [[EvilIsPetty end up cutting the funding for the park due to the staff falling behind schedule]]. To his credit though, writer!Drew eventually realized that this motive was too flimsy and stupid to justify Theodore pulling a FaceHeelTurn, and also that Theodore cutting the funding also felt more like a case of PokeThePoodle than a true act of villainy, and so he created Percival von Grimm to serve as the BigBad instead.
* Writer!Drew also originally planned for Cynthia to go so far as to [[MarshmallowHell get PE!Drew's head shoved in between her breasts]] over the course of their first meeting. For [[UnfortunateImplications obvious reasons]], Nathanoraptor had this part cut, due to being disturbed by how the scene was portrayed (basically [[DoubleStandardRapeFemaleOnMale portraying sexual assault as a funny thing when it's a girl doing it to a guy]]). [[HarsherinHindsight Given the #MeToo scandal several months later, this was probably a correct decision]].
* PE!Drew was initially planned to be a deconstruction/parody of characters like the ''Series/PrehistoricPark'' version of Nigel Marvin. Specifically, his reckless tendencies (which were present in Nigel and very common in all characters similar to him) were to be explicitly portrayed as capable of achieving desired results, but also immensely dangerous and capable of bringing great harm to himself and other people. Appropriately, he was also intended to have a very brave, charming, and charismatic, yet also abrasive, stubborn, and bull-headed personality that would chafe at being told no. And furthermore, the arc Nathanoraptor planned for him to have was to discover how his reckless tendencies were in fact ''not ok''. Unfortunately, when writer!Drew ended up first projecting some of his own real life personality traits (that didn't match up with PE!Drew's planned characterization) onto the character, and than later started trying to further change Drew into more of a straight equivalent of Nigel both before and after Cynthia's introduction, the subsequent clashes between the writers resulted in the character instead having a weird mishmash of both the deconstructive traits that Nathanoraptor had wanted as well as the more 'straight up Nigel' traits that writer!Drew had wanted.
* The original reason Cynthia was even created in the first place technically qualifies as this. Specifically, over the course of reading through the plans Nathanoraptor had in mind for the characters, writer!Drew ended up misinterpreting Nathanoraptor's attempts at having PE!Drew, Leon, and Jack form a [[Franchise/StarTrek Kirk-Spock-McCoy]] style trio as an attempt to have PE!Drew DemotedToExtra in favor of extra focus on Leon and Jack (whom writer!Drew personally considered 'just side characters'). Therefore, in an effort to ensure that PE!Drew (the supposed main protagonist) would still be able to have a decent amount of the spotlight focused on him via him having ''something'' to work with himself in regards to the plot and arcs, he created Cynthia with the plan for her to be a 'crazy girlfriend that would drive him insane in dealing with her'. Unfortunately, as described elsewhere on this page as well as under related entries on the main trivia and YMMV pages, these efforts both proved badly timed and ended up coming across as having less than ideal intentions in regards to other story elements that would have potentially suffered from the original plans involving Cynthia; which resulted in Nathanoraptor causing them to get heavily changed for the sake of salvaging the story.
* According to Nathanoraptor, if writer!Drew had had his way, just about all the other members of the rescue team would have potentially had their prominence downplayed and relevance reduced by virtue of PE!Drew and Cynthia assimilating several of the traits that had been previously assigned to Jack, Alice, and Leon.
* Writer!Drew initially never wanted Will and Matt to be included in the story at all and wanted their introduction scene at the beginning of "Passport to Hell" to be a scene that would have supposedly allowed for Cynthia's character to be better developed. In fact, writer!Drew's original plans for the chapter regarding Cynthia would have allowed this chapter to basically be her DayInTheLimeLight in which she got her personality and relationships with the other characters properly established after her introduction. Nathanoraptor swapped the intended character development for Cynthia (which he also claims to have been more of a case of CharacterShilling than of proper character development) out for introducing Will and Matt partially out of reader demand and partially out of their importance to Alice's character later in the story. Furthermore, as described below, the way writer!Drew tried to execute his plans ultimately proved problematic in regard to how other characters would have ended up getting treated.
* For further context on the Cynthia scene that got scrapped for the sake of Will and Matt's introduction, Cynthia was initially intended to be in the jeep with Jack during the scene where Jack is in a jeep for the sake of feeding the dimetrodons[[note]]in the final cut, the person in the jeep with Jack is just a random nameless keeper[[/note]]. In the version of the scene that would have included Cynthia, Jack would have said something along the lines of "I never knew you were this amazing!" immediately after they'd finished their work with the dimetrodons, to which she would have responded, "A lot of people say that about me." Writer!Drew's intentions for this scene were for both a chance to start work on establishing her personality and relationships/dynamic with the other characters, and also to show Cynthia as being, in his own words, 'another role model for Jack'. Unfortunately, as Nathanoraptor explains, writer!Drew's execution of this idea fell flat because of how the trait that Jack would have ended up expressing for the sake of establishing Cynthia as a new role model for himself[[note]]his tendency to latch onto any positive comment or action a person of higher authority than him sends his way and try desperately afterward to get himself in said person's good books[[/note]]was explicitly intended to be one of Jack's biggest character flaws[[note]]as this action was planned to be a result of his low self confidence[[/note]]. Therefore, the secondary reason behind Nathanoraptor changing this scene (the primary one being the one involving Will and Matt) was that he felt that it sent a bad message for allowing a display of one of Jack's flaws he needed to move past to be seemingly shown as a sign of Cynthia having a positive impact on him. Furthermore, he also felt that Cynthia needed to earn her prominence rather than immediately have it handed to her as well as that Jack's planned comment to her about 'being amazing' was (as described above) more of a case of CharacterShilling than of genuine CharacterDevelopment.
* On the continued subject of Cynthia, Nathanoraptor also initially considered having her actually be PE!Drew's girlfriend in the past prior to their work at Prehistoric Earth, which would have resulted in an explanation of their seemingly already knowing each other before Cynthia's introduction in ''The New Rulers'', as well as an info dumb on the fact that one of them broke the other's heart prior to their work at the park. Nathanoraptor, however, chose at the time not to include this idea because he felt it would be too much of a coincidence. [[CreatorBacklash He has since regretted putting too much thought in that idea and now considers the reason behind his decision not too include it as being too much of a nitpick]].

* The discussion in which Jack manages to get the idea on how to solve the dilemma involving the carnivore feedings was originally planned by writer!Drew to be between Jack and Cynthia. It was also planned by him for the comment that gets Jack to have his EurekaMoment be Cynthia very explicitly saying something about the jeep not having any people inside it. Nathanoraptor changed this in two ways to how it is in the final product. For starters, much like when writer!Drew had originally wanted Mia to be the one that Leon and Hedetet helped rescue from the brontoscorpio, he changed his mind and let Nathanoraptor have Jack's discussion be with Colette due to the two of them having an important RomanceArc between them in the future. Nathanoraptor also changed the comment that granted Jack his EurekaMoment to something that he felt would be more subtle.

* Furthermore, the ending of ''Passport to Hell'' was intended by writer!Drew to be much more focused on Cynthia. Nathanoraptor, however, felt it would be much more fair (and sensible) for it to be focused on Jack since he was the one who'd successfully helped solve the problem that had arisen at the park and he wanted Jack to be treated with all due credit and respect for as much.
* Writer!Drew originally wanted PE!Drew to blatantly explain to Jack about euparkeria being believed to be a direct evolutionary ancestor to dinosaurs during ''Life and Death Promised''. Nathanoraptor, changed it to have Jack mention the fact write as PE!Drew was working on mentioning it because Nathanoraptor felt that Jack would be in character to be smart enough to already know this information. Writer!Drew also originally wanted Jack's line before Leon's successfully distracting the therocephalians and leading them through the portal to be "[[WesternAnimation/TheLionKing What do you want us to do? Dress in drag and do the hula]]?'' Nathanoraptor changed this to "What do you want us to do? Douse ourselves in steak sauce and dress as a chew toy?" because he felt that this line would be much funnier (and more subtle), and the originally planned line was a little too much of a gratuitous (and pointless) ShoutOut.
* Writer!Drew initially wanted PE!Drew to kick Leon in the shins when Leon was about to correct him at the end about them having just done a mission in the Mesozoic Era at the end of Phase 1. Nathanoraptor changed it to Jack politely dragging him aside and whispering not to [[MomentKiller ruin the moment]] since he felt that would be funnier and also because it would have helped establish a planned character trait for Leon that ended up getting dropped.

* Writer!Drew initially wanted modern animals to be present in PE!Drew's office similarly to Nigel Marvin in the original ''Series/PrehistoricPark''. But then he changed his mind for reasons he chose not to disclose.
* There was originally going to be a line blatantly making clear the fact that someone had mysteriously deleted a message Drew had sent to Kyle and Nikolai during ''Degrees of Greatness''. Writer!Drew suggested that Nathanoraptor remove this line because it looked to unsubtle, and Nathanoraptor agreed that his co-writer had a point.
* For unexplained reasons, writer!Drew initially wanted Adrian to be seen speaking in what Nathanoraptor describes as a very weird street lingo over the course of this chapter. Nathanoraptor changed it so that Adrian would speak normally because he felt that writer!Drew's idea involving the 'street lingo' looked too weird.
* Writer!Drew also originally wanted the cymbospondylus to be much more obviously close in resemblance to [[DeviousDolphins dolphins]] (likely due to popular imagery of ichthyosaurs as resembling dolphins). Nathanoraptor, however, felt that cymbospondylus much more closely resemble [[NeverSmileAtACrocodile crocodiles]] and [[SlipperyAsAnEel eels]] than they do dolphins, and so he changed the cymbospondylus description accordingly.
* Writer!Drew initially planned for the attack against the cynodonts by the coelophysis to be relatively low key. Nathanoraptor chose to crank it up and make it more intense since he felt that would be a good way to remind the readers and characters that, despite their size, [[KillerRabbit coelophysis were still deadly predators in their own way]].
* Writer!Drew also didn't originally specify who was talking on the communicators to Nikolai and Kyle after they'd successfully gotten all the peteinosaurus in their aviary enclosure. Nathanoraptor chose to let Jack be explicitly the one talking to them at that time since he saw no reason not to do so.
* Writer!Drew initially planned to include a line of exposition that would have mentioned 'giant reptiles not being something that Linda would have been all that familiar with'. Nathanoraptor calmly told him that postosuchus were within the same size range as many modern-day large crocodiles (which, alongside komodo dragons, Linda would have logically been expected to have worked with in the past before being hired to work at Prehistoric Earth).

* It was initially going to be implied during ''All Great and Precious Things'' that the coelophysis had escaped a very large number of times. However, due to the context in which the escape in this chapter had occurred, writer!Drew felt that this idea would be too unsubtle a form of evidence of the sabotage going on behind the scenes. So Nathanoraptor deleted the line with the implication of multiple escapes and allowed the idea of multiple escapes from a group of small dinosaurs to be [[RefittedForSequel refitted for]] ''Fanfic/PrehistoricParkReimagined''[[note]]albeit, with compsognathus instead of coelophysis[[/note]].

* Nathanoraptor originally wanted the baby allosaurs found in ''All Great and Precious Things' to explicitly be Balerion's offspring. He and writer!Drew even ended up getting into some disagreements over the matter. Eventually, the baby allosaurs were made unrelated by blood to Balerion, and Balerion herself was made to instead adopt them rather than be their biological mother.
* It is also suspected by Nathanoraptor that writer!Drew initially wanted Cynthia to be Russian. Nathanoraptor, however, chose to write her as if she were British instead, and the new nationality for her ended up sticking.
* Leon was originally intended by Drew to not have a very good start in his allosaur training. Specifically, the very first day of his allosaur training efforts was supposed to [[HumiliationConga constantly go wrong]], as a homage to Tadashi and Baymax in ''WesternAnimation/BigHero6''. Nathanoraptor, however, thought it dragged out the story. As a result, Leon's training of the allosaurs went much more relatively smoothly from the very beginning and was played entirely seriously. On a similar note, writer!Drew also originally wanted all five of the young male allosaurus to be on the 'squad'. Nathanoraptor, however, felt that it would be more workable for only three of them to be on the squad, and so the squad was whittled down to [[Series/GameOfThrones Drogon, Viserion, and Rhaegal]].
* Speaking of the allosaur squad training, writer!Drew also originally planned for the initially planned hijinks to basically be the allosaurs chasing Leon around in a Yakety-Sax style sequence similarly to something from a Benny Hill comedy sequence due to believing that this would serve as AuthorAppeal for Nathanoraptor. Nathanoraptor, however, didn't think this worked due to both the pacing issues mentioned above and the fact that, despite Benny Hill being British, modern Brits [[OldShame actually feel embarrassed about being associated with him]] and largely prefer Monty Python style comedy over him (though to his credit, Nathanoraptor [[PetTheDog chose not to tell Drew about this latter detail]]).
* Drew also initially planned for Colette to be at the Allosaurus paddock watching Leon do the training instead of Nikolai (as he'd wanted for Colette and Leon to have a rivalry). Nathan, however, felt that this plot point would be too much of a repeat of Jack and Leon's rivalry from earlier in the story (though he wasn't necessarily opposed to the idea being given a shot in the subsequent reboot ''Fanfic/PrehistoricParkReimagined'').

* The 'instrumental theme tune' and narration similar to the kind featured in the original ''Series/PrehistoricPark'' series and the stories of the Extinction World mythos appeared in at least one of the earlier missions of phase 1 and were initially planned to be a staple of all future 'episodes'. Nathanoraptor, however, chose to scrap them since, unlike in the aforementioned material, there was neither a camera crew nor the premise of this story being the events of a TV-show. And without these elements around to provide an excuse, the 'instrumental theme tune' proved quite out of place and needless and the narration seemed too much like blatant attempts at breaking the fourth wall (which Nathanoraptor admits to not always feeling very comfortable with).

* Grumpy the megalograptis was initially planned to be amongst the massive swarm featured in the finale. Nathanoraptor chose to have him instead be a single solitary megalograptis that got rescued earlier in the mission due to both Grumpy's initially being planned to be amongst the larger swarm seeming like too much of a ContrivedCoincidence as well as Nathanoraptor's considering it much funnier for Kyle to have some experience with a single megalograptis prior to the arrival of an entire larger group.

* Nathanoraptor wanted to call the mesothelae spider megalorachne, but he and Drew eventually decided to just call them mesothelus in this story for the sake of simplicity. On a similar note, Pumpkin was originally planned by Nathanoraptor to be named Neith (after the Egyptian goddess of the hunt) as suggested by Flameal15K when the spider was planned to be the animal partner for a character Flameal15K had suggested for inclusion in Prehistoric Earth. Drew, however, made her be named Pumpkin instead (after a character from one his favorite anime, Akame ga Kill).

* Speaking of Colette and Nikolai, the scene where Colette, Jack, and Leon get comically 'attacked' by Pumpkin was originally intended to both only involve Colette getting 'attacked' and be more karmic in nature against her. Specifically, writer!Drew had wanted her to blatantly startle a keeper handling the arthropods into accidentally getting himself cornered by them simply [[ItAmusedMe for shits and giggles]] before Nikolai would have stepped in and stared the arthropods down into submission, followed by Pumpkin jumping upon Colette and sending her running out of the Carboniferous bug house screaming in fright. Nathanoraptor changed this to its current form in the final product because, in his eyes, this would have been a 2nd time that writer!Drew had tried to turn her into the resident bitch when she was explicitly supposed to be the resident ActionGirl instead (while also being a JerkWithAHeartOfGold at the very worst).
* Spiny the dimetrodon was originally intended to act like a dog for both RuleOfFunny and for the sake of promoting a separate fic. Nathanoraptor thought this would be too [[ItsTheSameNowItSucks cliche]] and unrealistic, and also believed that Spiny the way writer!Drew planned him to be was both a blatant ripoff of [[WesternAnimation/TheFlintstones Dino]] and an embodiment of the AllAnimalsAreDogs cliche (a major pet peeve of his), and had Spiny (alongside the other dimetrodons) altered to behave more like a cat or tegu lizard instead. Drew was [[CreatorBacklash not pleased]] with this change. Furthermore, Nathanoraptor also initially planned for the scenes with Spiny, Lubbock the petrolacosaurus, and Howler the hynerpeton to play out more similarly to a Tweety and Sylvester short (with Spiny chasing Lubbuck around the park ala Tweety and Sylvester, only for Spiny to end up encountering and getting scared off by Howler similarly to how the bulldog in Looney Tunes tended to do the same to Sylvester). Nathanoraptor also even planned for multiple other such shorts of a similar nature involving different newly rescued animals to occur over the course of the story. Writer!Drew, however, vetoed this idea for unexplained reasons and chose to have the scenes with the three critters in ''The New Rulers'' instead play out more like a Wile-E Coyote style scenario; something that he has probably forever regretted since due to how Spiny ended up having no more reason to be a prominently featured character as a result of his short-sighted vetoing of Nathanoraptor's idea. Furthermore, Nathanoraptor himself came to develop a [[CreatorBacklash scathing hatred]] of Spiny, Lubbock, and Howler's subplot due to his arguably superior idea getting shot down.
* Speaking of said subplot, Squishy the anomalocaris was initially intended to be in a tank in the back of the jeep that Spiny, Lubbock, and Howler ended up acccidentally hijacking, but the writers couldn't figure out a convincing reason for him to be there, so his involvement got scrapped. Considering how the fall off the cliff and crash that the jeep ended up taking in the final product could have likely killed Squishy[[note]] by virtue of either Squishy getting expelled from the tank and onto dry land, or the tank getting shattered[[/note]], this is probably for the best.

* Percival von Grimm initially didn't even exist in the story. More specifically, writer!Drew initially planned for ''Theodore'' ([[BigGood of all people]]) turn out to be EvilAllAlong and [[EvilIsPetty end up cutting the funding for the park due to the staff falling behind schedule]]. To his credit though, writer!Drew eventually realized that this motive was too flimsy and stupid to justify Theodore pulling a FaceHeelTurn, and also that Theodore cutting the funding also felt more like a case of PokeThePoodle than a true act of villainy, and so he created Percival von Grimm to serve as the BigBad instead.

* PE!Drew was initially planned to be a deconstruction/parody of characters like the ''Series/PrehistoricPark'' version of Nigel Marvin. Specifically, his reckless tendancies (which were present in Nigel and very common in all characters similar to him) were to be explicitly portrayed as capable of achieving desired results, but also immensely dangerous and capable of bringing great harm to himself and other people. Appropriately, he was also intended to have a very brave, charming, and charismatic, yet also abrasive, stubborn, and bull-headed personality that would chafe at being told no. And furthermore, the arc Nathanoraptor planned for him to have was to discover how his reckless tendancies were in fact ''not ok''. Unfortunately, when writer!Drew ended up first projecting some of his own real life personality traits (that didn't match up with PE!Drew's planned characterization) onto the character, and than later started trying to further change Drew into more of a straight equivalent of Nigel both before and after Cynthia's introduction, the subsequent clashes between the writers resulted in the character instead having a weird mishmash of both the deconstructive traits that Nathanoraptor had wanted as well as the more 'straight up Nigel' traits that writer!Drew had wanted.
* The original reason Cynthia was even created in the first place technically qualifies as this. Due to how writer!Drew had come to misinterpret Nathanoraptor's attempts at having PE!Drew, Leon, and Jack form a [[Franchise/StarTrek Kirk-Spock-Mccoy]] style trio as an attempt to have PE!Drew demoted to extra in favor of extra focus on Leon and Jack (whom writer!Drew personally considered 'just side characters'). Therefore, in an effort to ensure that PE!Drew (the supposed main protagonist) would still be able to have a decent amount of the spotlight focused on him via him having ''something'' to work with himself in regards to the plot and arcs, he created Cynthia with the plan for her to be a 'crazy girlfriend that would drive him insane in dealing with her'. Unfortunately, as described elsewhere on this page as well as under related entries on the main trivia and YMMV pages, these efforts both proved badly timed and ended up coming across as having less than ideal intentions in regards to other story elements that would have potentially suffered from the original plans involving Cynthia; which resulted in Nathanoraptor causing them to get heavily changed for the sake of salvaging the story.

* There was originally going to be a line blatantly making clear the fact that someone had mysteriously deleted a message Drew had sent to Kyle and Nikolai during ''Degrees of Greatness''. Writer!Drew suggested that Nathanoraptor remove this line because it looked to unsubtle, and Nathanoraptor agreed that his cowriter had a point.

* Writer!Drew originally wanted the male postosuchus to be named Kenge, after the male monitor lizard from ''WesternAnimation/TheLionGuard''. Nathanoraptor vetoed this idea due to it leaving no immediate corresponding appropriate name for the female, and so the two ended up named Rojo and Rosa instead.

* Nikolai was initially planned to end up heavily involved in the conspiracy thriller style plotline that unfolded later in the story involving the saboteurs and animal smugglers. His scenes in TheStinger of ''Spirits of the Silent Forest'' were even written as a means to foreshadow these plans. However, these plans in question were thought up long before Cynthia was created and introduced into the story. And while the plans were initially still considered for use, they ultimately got changed later to something different for the sake of pacing and better manageability of the multiple other plot points and arcs that had already taken form by that point[[note]]for what it's worth though, the stinger did still allow for reasonable grounds for Nikolai's later targeting by the black-ops squad during ''The Devils Here''[[/note]].

* The male pteranodon that stayed on the boat over the course of ''The Wavering Gulfs'' was originally planned to be a secondary animal partner for Adrian alongside Keehar the rhamphorhynchus. He was even originally considered to be named Nigel (as a tribute to Nigel Marven himself!). Furthermore, the scenes where the pteranodon interacted with Keehar were originally meant to lead into a meaningful moment that was planned at the time to occur later in the story. His planned bond with Adrian ended up cut for presumably pacing reasons or lack of room for inclusion alongside the various other plot points to be juggled around, and he was ultimately named Mert for unknown reasons.

* During ''New Beginnings'', the initial plan for rescuing one of the anomalocaris involved Leon blatantly ''pushing'' Leon into colliding against the anomalocaris, at which point he and the anomalocaris would have both ended up sent through the portal. Leon was also originally planned by writer!Drew to be TheVoiceless all the way until the very next mission, ''Devils of the Deep'' (with what was then intended to be his very first ever line in the whole story being designed to serve as a LampshadeHanging for this prior status). Nathanoraptor changed this to be the way it is in the final product since, in his eyes, writer!Drew's initial plans didn't really work that well or properly do Leon justice.

* Drew initially wasn't entirely certain that Jack would be interesting enough to carry a story on his own. Nathanoraptor, on the other hand, had enough faith in the character's ability to carry a story to convince Drew to give him a chance.
** To Drew's credit though, Jack was also initially not planned to take the major role that he ended up taking. The initial 'leading trio' was originally intended to be Drew, Leon, and Adrian (due to them being written as close friends). But later on, after Jack's dialogue in "The First Steps" was written, the authors soon came to realize that Jack was a lot more interesting than Adrian. And as a result, Jack ended up getting his prominence in the story significantly boosted while Adrian ended up becoming immensely OutOfFocus throughout multiple parts of the story.
** Furthermore, Drew initially pushed for Cynthia to be made into a [[SpotlightStealingSquad secondary main character]], particularly for the sake of allowing her and Drew to be people to view Jack and Leon's (respectively) storylines through due to his then low faith in the characters' (especially Jack's) ability to carry a story. Nathanoraptor was not amused by this on account of how he had much more faith in Leon and Jack being able to carry a story on their own than his co-author did, and in the end Nathanoraptor got his wish.
* As mentioned above, Jack wasn't originally planned to be the major character he ended up becoming. Rather, he and Alice were supposed to serve as supporting protagonists to work alongside the 'main trio' of Drew, Leon, and Adrian. This was also intended to be highlighted with Jack serving as little more than a comedy sidekick with a penchant for [[LamePun lame puns]]. However, a mixture of both Nathan and writer!Drew noticing the unexpected level of depth they'd managed to give him alongside the planned penchant for puns, and difficulty in figuring out appropriate puns for Jack to have available for use in every subsequent mission led to them boosting his prominence as described above.

* The original reason Cynthia was even created in the first place technically qualifies as this. Due to how writer!Drew had come to misinterpret Nathanoraptor's attempts at having PE!Drew, Leon, and Jack form a [[Franchise/StarTrek Kirk-Spock-Mccoy]] style trio as an attempt to have PE!Drew demoted to extra in favor of extra focus on Leon and Jack (whom writer!Drew personally considered 'just side characters'). Therefore, in an effort to ensure that PE!Drew (the supposed main protagonist) would still be able to have a decent amount of the spotlight focused on him via him having ''something'' to work with himself in regards to the plot and arcs, he created Cynthia with the plan for her to be a 'crazy girlfriend that would drive him insane in dealing with her'. Unfortunately, as described elsewhere on this page as well as under CreatorBacklash on the main trivia page, these efforts both proved badly timed and ended up coming across as having less than ideal intentions in regards to other story elements that would have potentially suffered from the original plans involving Cynthia; which resulted in Nathanoraptor causing them to get heavily changed for the sake of salvaging the story.

* Writer!Drew initially planned for the attack against the cynodonts by the coelophysis to be relatively lowkey. Nathanoraptor chose to crank it up and make it more intense since he felt that would be a good way to remind the readers and characters that, despite their size, [[KillerRabbit coelophysis were still deadly predators in their own way]].

* When the plan was still for Cynthia to accompany Jack and Alice, the Utahraptor pack was initially planned to outright attack the trio during their encounter before getting sent through the portal. But after the decision was made to have Cynthia and Adrian switch places (and for Jack himself to have one of the Utahraptors as an animal partner), the planned scenes and plot points that the attack against Cynthia, Jack, and Alice ended up pointless and discarded. Therefore, the planned Utahraptor attack was itself discarded along with the now obsolete scenes that were initially planned to follow it.

* Writer!Drew also initially planned for one of the other team members (possibly Leon) to accompany PE!Drew to the t-rex nest and end up heroically pushed through the portal by him seconds before PE!Drew's ending up marooned. This was changed to PE!Drew going to the rex nest alone due to a mixture of writer!Drew realizing that the way he originally planned for the subsequent scenes to unfold was starting to overcomplicate matters and Nathanoraptor wanting PE!Drew's marooning to be entirely his own fault and have no heroic, brave, or self-sacrificial overtones to it for the sake of the planned arc he had for the character.

** Writer!Drew initially planned for it all to just be relegated to a side plot during ''Ten to Midnight'', with von Grimm having several moles in the park, who would be killed and eaten by Sharptooth, Zira, and other carnivores while Percival himself would be crushed to death in a building trampled by the herbivores (the fate that ended up befalling Frank in the final product). And all without anyone even being aware of the smuggling operation or anything untoward at all. Nathanoraptor, however, felt it would be too anticlimactic to have the bad guys [[DroppedABridgeOnHim so abruptly killed off in one of the missions prior to the finale]] [[AntiClimaxBoss after having been so strongly built up prior]].

*** Subsequently, Jack was initially going to trick one of the more idiotic mooks into calling Keehar a dinosaur within earshot of the pterosaur (this was before the plan for this being Keehar's BerserkButton got scrapped), causing Keehar's resulting fit of rage to distract all the mooks long enough for Jack himself to get ahold of the remote that he then used to release the captive animals in the area the way he does in the final product, all of which would have killed the mooks while he himself, plus Colette and Adrian, would have then ganged up on and taken down the boat's captain. Alice, Will, and Raksha would have been saved from Scarface by Baloo once again (with help from Raksha). And Cynthia and Leon would have managed to escape from the animal holding chamber in time to come bursting into the scene with the allosaurs in time to save PE!Drew and Nikolai. From there, the allosaurs would have killed all but Frank, who would have willingly surrendered in these versions of the events, and Duncan, who would have escaped from the area, gotten into a jeep or boat, and tried to escape from the base with the inferior jury rigged portal. Unfortunately for him, Scarface would have ended up in the same jeep or boat as him, and would have then [[KilledOffscreen killed him offscreen]] in a GoryDiscretionShot before then leaving the subsequently crashed vehicle and gone rushing off into the wild.
