Nigel MarvenThe founder and owner of Prehistoric Park. He travels to the past in order to bring extinct prehistoric creatures back to life.
- Badass Bookworm: Knows all about the prehistoric creatures he's about to face and constantly tries to capture them. Most of the time, he succeeds.
- Expy: Think of him as a time-traveling Steve Irwin.
- Out of Focus: Downplayed: he's still in the spotlight, but the younger characters are starting to displace him.
BobThe Head Keeper of the park. In charge of cleaning, feeding, and taking care of the resident animals. Consequently, he often suffers the shenanigans that happened in the park.
- Adaptational Intelligence: Though he was by no means stupid in canon, he has a few moments of this. For example, in the original series, communication problems lead to him getting Nigel an ordinary birdcage when he wanted something very different (since he wanted to capture a terror bird). Here, he understands that Nigel's bird is much too big for a regular birdcage, and knowing that he's going to prehistoric South America, comes to the logical but incorrect conclusion that he wants a cage for a rhea ancestor. As a result, the only problem with the cage he builds is that it's half as big as it should be.
- Additionally, the cage would have been perfectly sized for several species of terror birds, it's just that Phorusrhacos is one of the larger ones.
- Butt-Monkey: Usually on the receiving end of the whatever bad things that the prehistoric creatures brought, mostly from the Titanosaurs. Gradually, this status has shifted to other characters.
- Cool Old Guy
- Only Sane Man: The one who usually complains to Nigel whenever he's planning to bring back the dangerous creatures back to the park or points out potential issues. He's still fond of them all, even the Titanosaurs, but he will still point out issues.
- OOC Is Serious Busniess: Actually joined the away team in Time of the Titans to rescue the giants of the Jurassic. Why? Stegosaurus is his favorite dinosaur, and he wanted to help bring some back.
- Out of Focus: See Nigel's entry for more details.
SuzanneThe head-vet of the park. Tasked with treating the injured animals and looking after their health.
- Hospital Hottie
- Out of Focus: Again, see Nigel's entry for more details.
- Team Mom: Especially in one episode where she had to nurse the baby Smilodon because his mother's milk has ran out.
Tristan SaurusOne of the park's newest recruits, and second in command of the away team.
- The Ace: Among his siblings.
- Conspiracy Theorist: A Downplayed example - he's apparently a believer in some types of cryptids.
- He also thinks it is possible that naturally occurring time portals could cause animals to travel through time, which would explain several cryptid legends. Later chapters indicate he is right on the money.
- Exact Words: Told Nigel way back in Bistahi Destroyer that he was familiar with the time portal because he was hit by a Frisbee his dad through backwards in time. The Untold Stories revealed that while this was his first experience with the time portal, this was not his first experience with time travel.
- The Leader: Of the younger recruits for the park.
- Number Two: To Nigel when on missions.
- Multi-Ethnic Name: He has a Welsh first name and a Greek last name.
- Nepotism: Downplayed - he was made a part of the away team per request of his dad (who helped build the park), but it's clear he takes the position seriously. Additionally, him being second in command isn't really official, everyone just treats him as such.
- Nice Guy
- Noodle Incident: Apparently, he learned about his father making the time-portal when he was hit by a Frisbee his dad launched backwards through time. However, this was not his first experience with time travel.
Tiberius SaurusCo-founder of Prehistoric Park.
- Crazy-Prepared: Made sure to arrange online classes for his children and his friends so that they would not be forced to go home when school started, as he knew they would likely be unwilling to leave the park after just arriving at it.
- Fiction 500: Implied, as he apparently developed the time portal out of his own pocket.
- The Ghost: Hasn't appeared yet, but his kids make up a good portion of the recurring cast.
- Good Parents: Implied, as the team hasn't said anything to indicate he was anything else.
- Multi-Ethnic Name: Latin first name, Greek surname. Downplayed, since Saurus is a Latinized spelling.
Vera CalderaOne of the other members of the away team, and a friend of Tristan.
- Kid with the Leash: Is well on her way to becoming this for Finn.
- The Medic: She's one of the people helping Suzanne teach the next set of veterinarians how to care for the park's various inhabitants.
- No Periods, Period: Averted - Finn's segment in the second part of Kaibab's Hunter makes it clear she had hers. Since it's from Finn's perspective, though, it can be hard to notice.
- Not So Above It All: While she does enjoy things that would probably scare most people, she still flinches in surprise when she watches a sundew eat a fly.
- Tomboy with a Girly Streak: Either this or its inverse, as while she's show to enjoy girly things, she doesn't really mind being around giant predatory dinosaurs. In fact, the resident she cares the most about is Finn, who is giant carnivorous dinosaur.
AliceAnother member of the park's away team.
- The Cheer Leader: Used to be one, but has graduated.
- Dumb Blonde: Averted heavily: she's very knowledgeable about Prehistoric Life.
- Not So Above It All: For all of her Tomboy traits, she Screams Like a Little Girl when confront with Michelle's driving.
- Shameless Fanservice Girl: When she learns Lucas is taking pictures of her, while she is rather angry at him, she has no problems with posing in some rather risqué ways for him She also lets him keep some of the pictures, so long as he gives her copies and doesn't show anyone else.
LucasYet another member of the parks away team.
- Conflicting Loyalty: Between his parents and the park. His parents are reporters and would love to find an amazing story to make them rich and famous, something the park would definitely count as, but he was required to keep quiet about it due to a contract he signed after his first mission. Notably, hes perfectly aware they would refuse to break the story (Tiberius, Tirstans father and owner of the park, is there friend, and they refuse to betray their friends), hes just annoyed he cant tell them about it at all.
- Groin Attack: He was subjected to this by Alice as punishment for his perverse antics as described in the trope entry after the next. Apparently, she did it to him the way Yang did to Junior.
- Intrepid Reporter: His parents are this.
- The Peeping Tom: A variation - he takes a bunch of pictures of Alice in a swimsuit without her consent. The minute he realizes that she knows he is doing this, he goes rigid, before deciding to continue taking photos, resigning himself to whatever punishment he receives.
- The Smart Guy: The Tristan's friends.
Elise SaurusTristan's eldest sister, and a member of the away team.
- Sixth Ranger: Share's this role with her brother Sean, as the two of them arrived a little late to the park due to having to finish up summer camp.
- Shout-Out: Word of God is that she is one to Elise Lowing.
Sean SaurusTirstan's eldest brother, and also a member of the away team.
- Crazy Cat Lady: Gender Inverted, Downplayed example in regards to birds - while he has a reason to possess them (he's a falconer), the shear number of birds he keeps with him (six, most of which are birds of prey) is rather absurd. And that is BEFORE he adds pterosaurs into the mix!
- Fluffy Tamer: He has this dynamic with all of his flying companions, which include at least one vulture, two falcons, a hawk, a buzzard, several flying foxes (fruit bats), and a rhamphorynchid pterosaur (which may or may not be a dimorphodont according to modern research).
- Noble Bird of Prey: Is an experienced falconer, to the point he surpasses his brother in the field.
TedOne of the park's newest recruits, he cares for the aquatic animals.
TerenceThe park's juvenile male Tyrannosaurus.
- Adaptation Expansion: Gets more scenes in this story, to the point he eclipses Matilda in number of appearances.
- Amazing Technicolor Wildlife: Based on the artwork the author has made, Terence is quite literally every color of the rainbow.
- Bioluminescence Is Cool: Has bioluminescent spots along his flanks. The author is well aware that tyrannosaurs probably didn't have them, but included them any ways because they look cool.
- Feathered Fiend: Is fully feathered.
- Gentle Giant: Surprisingly, he is one. Case in point - when he encounters a Cosgriffius (a marine temnospondyl amphibian) trying to run into the ocean (Cosgriffius is an oceanic amphibian), he actually helps it into the waves. Keep in mind that, while Terence wasn't going to eat the overgrown salamander (he thought it might be poisionous), he still had no reason to help it into the water.
- Hidden Depths: Is a surprisingly good swimmer and likes seafood (specifically, sharks and turtles). Word of God is that this is based off of something he read on DeviantArt, noting how there were plenty of giant fish and turtles in the rivers that occupied T. rex's home range, and it would be very unlikely for a carnivore (especially one of Terence's size) to ignore such a large amount of food.
- Odd Friendship: With Willow the Thescelosaurus and an unnamed alverezsaur, both of whom clean his teeth. He's docile enough to them that they frequently break out of their exhibits to spend time cleaning him.
- Stock Animal Diet: Defied: among the things Terence is shown eating are turtles, as well as a dead shark.
- Stock Dinosaurs: The stock dinosaur.
- Tyrannosaurus rex
WillowA Thescelosaurus and Terence's friend.
- Odd Friendship: With Terence - while Willow and Terence's relationship is analogous to that of a plover and a crocodile, respectively, both are surprisingly devoted to each other, as Willow chooses to stay near Terence when the later is in medical care following his fight with Matilda.
MatildaThe park's juvenile female Tyrannosaurus.
- Aww, Look! They Really Do Love Each Other: Inspite of her attempts to kill Terence, she has also brought him food from her travels around the park.
- Demoted to Extra: A side effect of Terence getting Adaptation Expansion.
- A Day in the Limelight: Kaibab's Hunter and The Double Crested Lizard focus on her when the narration returns to the park.
- Freudian Excuse: A Justified one, when taking the fact that she is an animal into account: her parents come from different populations of Tyrannosaurus that have different instincts on who holds a territory - her father comes from the South, where males hold land, but her mother comes from the North, where females defend territories. The conflicting instincts are what leads her to constantly attack Terence, either to evict him or force him to acknowledge her as pack leader. Terence's refusal to do so is due to the same instincts, and it's been implied the park's attempts to separate them are just making things worse.
- Shared Family Quirks: Interestingly, she has one with Terence - both befriend animals vastly smaller than they. Terence is friends with Willow and an unnamed Alverezsaur, while Matilda has bonded with a pair of Paleosaniwa.
SueThe park's adult female rex, and Terence and Matilda's mom.
- Meaningful Name: She's named after one of the most complete Tyrannosaurus skeletons ever found.
- Out of Focus: Doesn't get featured nearly as often as her kids. Somewhat Justified, though - she sustained severe injuries in the first chapter of the story and thus, probably needed some time to heal. She's also older than both of her kids, so she may simply not be as active.
- Spared by the Adaptation: Due to some quick thinking by Nigel and (apparently) having less severe injuries in canon, she is rescued and taken to Suzanne, who manages to heal her.
TheoOne of the park's male Triceratops.
- Last of His Kind: Nope - this time around, Nigel also rescued the juvenile female that Sue was trying to kill, so Theo is not the only one of his kind.
- In Spite of a Nail: However, as the female is the only other Triceratops of his species that was rescued (Nigel also rescued eight Triceratops prorsus), Bob still has to make the 'triceratops tractor' for him to fight... at least until Nigel and co. go back to rescue more Triceratops in Death of a Dynasty.
North and SouthA pair of Dakotaraptors.
- All There in the Manual: The explanation of why they were present to harass Nigel (and consequently get rescued) in the first chapter is only found in the epilogue of another of the author's stories, Walking With Dinosaurs The N Ext Chapter. It turned out they were following the Ornithomimus flock Sue had been chasing, and were trying to snatch one up when they first saw Nigel, who they thought would've made a better meal.
- Family Theme Naming: Are named after the two Dakotas.
- Feathered Fiend: Are both fully feathered.
- Raptor Attack: Averted - Word of God indicates they are fully feathered.
MarthaThe park's Wooly mammoth.
- Fish out of Water: Averted this time around, as the park has an actual tundra region in it. The narration notes how strange it is that a tropical island has a tundra on it.
- Honorary Aunt: To the park's elephant calf.
- Last of Her Kind: The only Wooly Mammoth left, as Nigel didn't rescue any others during his mission to Ice Age Europe and Siberia. She isn't the park's only prehistoric elephant relative, though, as Nigel rescued many others during the Great American Safari.
ZhaoOne of the park's Microraptor
- Amazing Technicolor Wildlife: Downplayed: She's got iridescent black feathers.
- Extreme Omnivore: Downplayed example: Zhao is briefly shown eating clay. Living birds (such as macaws) also do this, and Zhao only manages to find the clay because she was following the macaw that she share's Nigel's den with.
- Feathered Fiend: Subverted: she's fully feathered, but isn't a danger to anyone bigger than she is.
SabrinaThe park's female Smilodon populator.
- Spared by the Adaptation: Due to Nigel and Saba splitting off, they are able to save both Sabrina and her remaining cub.
- Stock Dinosaurs: Played With: While Smilodon is a stock genus, Sabrina is a member of the larger species S. populator, rather than the more famous S. fatalis.
PhilThe park's male Phorusrhacos.
- Feathered Fiend: Downplayed: While he is a giant carnivorous bird, he's rather tame, and is more of a nuisance than a threat to the staff.
BenThe park's Arthropleura.
- Big Creepy-Crawlies: The largest arthropod to ever walk on Earth. However, he's so large that he has lost his creepiness factor. It also helps that he prefers not to sneak up on people.
- Creepy Centipedes: Averted, see above. Additionally, he's a millipede, not a centipede.
- Gentle Giant: He may be a millipede that can stand up to look a human in the eyes, but he is surprisingly docile.
- Gilded Cage: His exhibit unintentionally amounts to this: while its very large and has plenty of food, due to his method of breathing, he can't actually leave it. Not that he seems to mind.
DianeThe park's female Deinosuchus.
- Boring, but Practical: Noted in her focus chapter of Inside Their World: Crocodiles have been around for so long because their bodies are the most efficiently built for surviving as riparian ambush predators. As a side effect, while most animals need a little while to adapt to the park, she does so almost instantly.
- Never Smile at a Crocodile: Averted
BistahiA male Bistahieversor.
- Androcles' Lion: Is somewhat docile towards Terence due to the latter saving his life.
- Odd Friendship: With Terence.
- Seldom-Seen Species: Bistahieversor is not one of the most well known tyrannosaurs.
- Tyrannosaurus rex: He's a close cousin.
BathosA male Bathornis fricki.
- Feathered Fiend: He's a giant, flightless, carnivorous bird. It comes with the territory. However, he isn't pointlessly aggressive.
- Seldom-Seen Species: Bathornids have never been portrayed in fiction before, as their role is usually filled by terror birds. Though, it is likely the two are related.
TerminatorA male Daeodon.
- Extreme Omnivore: Will eat anything short of animal waste.
- Scavengers Are Scum: Averted: he's intimidating, but not evil.
- Seldom-Seen Species
FinnA male Acrocanthosaurus.
- Amazing Technicolor Wildlife: His back is bright blue.
- Badass in Distress: Is on the verge of dying due to starvation when he's rescued.
- Big Eater: Comes with being a giant carnivorous dinosaur.
- Earn Your Happy Ending: He was half starved, dehydrated and sick when he found them, but his constant migrating in search of food was rewarded with him being rescued by the team and being sent to Prehistoric Park, ensure he won't ever go hungry again.
- Feathered Fiend: Has a few sparse feathers on him.
- Hidden Depths: Is implied to have seen the ocean at least once, as he's able to recognize a sponge for what it is when Vera uses one to clean him.
- Last of His Kind: Word of God is that he was the very last Acrocanthosaurus in existence when the team rescued him, as they were supposed to have disappeared several million years before the mission he's rescued in took place.
- Meaningful Name: Acrocanthosaurus is unique among carnosaurs for having large vertebral spines, which could have supported a sail/fin when the animal was alive. Alternatively, they could have supported a hump.
- The Nose Knows: Can recognize various traits about animals entirely from how they smell, including their gender and, if female, whether or not they are in heat. It also tells him when Vera undergoes her monthly periods, though he honestly has no idea what those are.
- Nothing but Skin and Bones: He was getting very close to this when the team rescued him, but now he's getting better.
- Odd Friendship: With Vera. Vera is noted to be a girl who loves nature and cute animals, yet Finn is a giant carnivorous dinosaur who tried to eat her.
- The issues she'd have with Finn attempting to eat her are mitigated by the fact that said attempt amounted to taking one step forward before collapsing from exhaustion.
- He's friendly enough with Vera that, after initially being unwilling to let her touch him, he lets her give him a bath.
- Reality Ensues:
- When the team first rescues him, he's practically on death's door and tires very quickly. Even after a few days of care, he still isn't back to full strength.
- Even if he trusts Vera, he still won't let her touch him. At least, not initially.
- Seldom-Seen Species: Acrocanthosaurus is not one of the most well known dinosaurs, though it has become increasingly popular in recent years.
Prehistoric DragonA male Prehistoric Dragon
- Breath Weapon: It's a dragon, what did you expect?
- Dynamic Entry: Lands on and pins down a hadrosaur as a pack of Dryptosaurus chases after the dinosaur.
- Giant Flyer: Unsurprisingly.
- Nice Job Fixing It, Villain!: While not a villain, the above mentioned Dynamic Entry ends up saving the duck-bill's life, as it is able to retreat into the present when the dragon becomes too distracted fighting the tyrannosaurs.
- Unexpected Character: Given that the series has so far only included animals that did or could have existed, the mere presence of an entirely fictitious animal is quite a surprise.
- Walking Spoiler: Given that it massively changes the nature of the story, this should come as no surprise. It is an entirely fictitious animal in a series that has, so far, only included creatures that did or reasonably could have existed in the past.
Big AlA male Allosaurus fragilis, known for the sheer number of injuries he suffered in life.
- Accidental Hero: Saves a trio of Dryosaurus when he knocks out the Ceratosaurus chasing them with a Tail Slap. He literally did not even know the predator was there until after the fact.
- Androcles' Lion: Saves Tirstan from a Saurophaganax as repayment for feeding him earlier in Time of the Titans.
- Adaptational Badass: Never won a fight in his original series, but manages to knockout over a Saurophaganax, defeat four Jurassic Park raptors, and still have the strength to knock out a Ceratosaurus using his tail entirely by accident.
- Handicapped Badass: Has a broken toe and a broken arm, not to mention several other injuries, but still manages to win every fight he gets into. The only time his injuries are brought up is when it is noted that his toe injury makes running painful.
- Mexican Standoff: Has one with a Columbian Mammoth. It ends when both are distracted by a deer.
- Spared by the Adaptation: Is rescued and sent to the present, where he is already receiving medical treatment.
- Taught by Experience: Having learned from his experiences in The Ballad of Big Al, when he finds another female of his kind, he offers her a gift before attempting to court her, and backs down when she wants her space.
- Walking Spoiler: Considering his rescue was not hinted at in any way, shape, or form, yes.
- The Worf Effect: Inflicts this on a Ceratosaurus without even trying.
SantoThe Protagonist of the second volume of Ricardo Delgado's Age of Reptiles.
- Arch-Enemy: A pack of Ceratosaurus nasicornis, for good reason.
- Walking Spoiler: About the same as the Prehistoric Dragon in that regard, as he was only given about one chapter of Foreshadowing.
AliciaA female Allosaurus fragilis with a damaged lower jaw.
- Body Horror: Her lower jaw pulverized by the dying blows of a Diplodocus, and while it eventually healed, it did so at an unnatural angle. I no way does this impair her ability to hunt.
- Canon Immigrant: Is from another of the author's stories, Walking With Dinosaurs: The Next Chapter.
- Ship Tease: With Big Al, as she is shown to be receptive to his courtship displays and considers him a suitable mate.
Jurassic Beetle QueenA large arthropod from the Jurassic Period.
- Animals Not to Scale: Type 2 - it was sized down because, per Word of God, the original size was ridiculously large for a Jurassic arthropod.
- Bizarre Sexual Dimorphism: Expected from a eusocial insect.
- Unexpected Character: Seriously, who expected her to show up?!
Small CrestA Rhamphinion that Sean has begun to train.
- Exactly What It Says on the Tin: He doesn't have a very large crest on his head.
- Ptero Soarer: Averted - he's depicted very accurately.
- Seldom-Seen Species: Rhamphinion has never been featured in fiction before.
- Small, Annoying Creature: At the moment - Sean hasn't really had much success training it.
Female Jurassic World BrachiosaurusExactly What It Says on the Tin
- Refugee from TV Land: The Jurassic Park franchise is explicitly confirmed to be fictitious in this story, making her appearance all the more surprising.
- Spared by the Adaptation: The team gets her off the island before she can be either choked out by the volcanic fumes or roasted by the heat, though it is made pretty clear that this was a close call.
- Unexpected Character: Up to Eleven - there was exactly one line of dialogue indicating she would appear, and that was more or less treated as a joke. Additionally, she's established as being fictitious In-Universe.
- Walking Spoiler: Up to Eleven - saying anything other than the fact that she is female will spoil a lot of important events for the latter parts of Time Of The Titans.
A set of hybrid animals unknowingly brought to the park during the unexpected mission to Jurassic World
