The first dinosaur to appear, and the most seen critter in this episode.
- Action Survivor: The one animal along with the cynodonts, Peteinosaurus and Plateosaurus that survived the trials and tribulations of the Triassic. Placerias and Postosuchus, to put it bluntly, weren't so lucky.
- Amazing Technicolor Wildlife: Perhaps one of the most brightly colored dinosaurs in the series.
- Eats Babies: Of their own kind! And the cynodonts...
- Fragile Speedster: It is more agile and faster than any other reptile of its era.
- The Swarm: At the end of the episode it gangs up to kill a dying Postosuchus.
- Villain Protagonist: Not exactly the most sympathetic main character of the series.
- Zerg Rush
A close relative of mammals.
- Action Survivor: Represents the future of the mammals.
- All Animals Are Dogs: They are decidedly dog-like in their behaviour.
- Ape Shall Never Kill Ape: Averted.
- Eats Babies: Their own babies.
- Mix-and-Match Critters: Like a mix between a lizard and a dog.
- Offing the Offspring: When they have to move out because of the Coelophysis.
- Papa Wolf: Until the Coelophysis discover the burrow and he decides the young aren't worth defending anymore at least.
- Ridiculously Cute Critter: The cubs. And then they had to die....
- Shoot the Dog: The narration acknowledges that the Cynodonts eating their babies was a necessary evil; if they are to move out and start anew, they won't be able to bring their young with them. It was likely a choice between killing the young quickly or leaving them to slowly starve to death...
The species chosen to represent the obsolete basal synapsids of the past.
- Butt Monkey: Representing all the species that can't survive the Triassic, and basically serves the episode simply as prey item for Postosuchus and Coelophysis. (However, it must be noted that no single species dominated the entire face of the Earth as they did, and none since save humans.)
- Dumb Muscle
- Mighty Glacier
The main large predator of the time period. A quasi-crocodilian creature.
- Adaptation Expansion: The cause of the Postosuchus' injury is never clearly explained; the narrator only said it was injured during its last hunt. In the book, however, it is stated the Postosuchus fights a Plateosaurus and was defeated and injured by it. Furthermore, it tries to give one last fight against the Coelophysis pack and manage to kill one before succumbing to its wound.
- Alas, Poor Villain: Technically it is no villain and just a predator, but its death nonetheless is one of the most depressing scenes in the series.
- Armor Is Useless: And no hindrance to the Coelophysis in the end.
- Badass in Distress: It was injured in the middle of the episode, the injury ultimately lead to it's agonizing death near the end of the episode
- Cool Versus Awesome: In the book it fights a Plateosaurus.
- Establishing Character Moment: Eating a Placerias alive.
- Never Smile at a Crocodile: Not a true crocodile, but still.
- Prehistoric Monster: Played With.
- Somewhere, a Palaeontologist Is Crying : Its marking behaviour is rather controversial and raised some critics from scientists, as no evidence suggest such behaviour. It was also far too slow and clumsy, and should have been at least facultatively bipedal.
Appearing only in the end, as a harbinger of the takeover of the dinosaurs.
A small pterosaur, appearing in a small role.
- Action Survivor: Implied, seeing as it represents the future success of the pterosaurs (who would one day rule the Mesozoic skies).
- Hero of Another Story: Has a lot of scenes, but never interacts with the other animals.
- Misplaced Wildlife: Actually came from Germany and Italy.
- Ptero Soarer: Not too inaccurate, but still suffers from several issues.
Time Of The Titans:
A large sauropod, and the main protagonist of the episode.
The main antagonist of the episode, and the largest predator in the episode.
A small carnivore, harassing the young early on.
- Disc One Final Boss: The antagonist in the early days of the Diplodocus' youth, but by the time they're grown, he's no longer a threat.
- Eats Babies : Kills a baby Diplodocus.
- Feathered Fiend: Oddly the only theropod besides Iberomesornis who has feathers.
- Fragile Speedster: Small and swift, but not very tough.
- Oh, Crap: When he sees that his former prey is too big for him to tackle.
Appearing in a minor role, confronting the Allosaurus
- Accidental Hero: Saves the young Diplodocus from the Allosaurus accidentally. On the other hand, it also kills one of them by accident.
- Bad Ass: The Allosaurus doesn't even dare to attack it, for a good reason...
- Beware My Stinger Tail: Its main weapon of defense
- Cool Versus Awesome: Almost happen between it and the Allosaurus, but the predator decide to retreat before fighting it.
- Dumb Muscle: Had the smallest brain of all the dinosaurs of its size. Still, it's not an easy target.
- Rule of Cool: The flushing of blood into its plates.
- Stock Dinosaurs
A small pterosaur, living among the Diplodocus
A small ichthyosaur, and the main protagonist of the episode.
A large sea reptile, and the main antagonist of this episode. Also appears in Sea Monsters
- Adaptational Badass: It wasn't really the biggest predator on the planet, though still a formidable marine carnivore.
- Alas, Poor Villain: As with the Postosuchus in the first episode.
- Bad Ass: The biggest predator on the planet (at least in the series); what else do you need to know?
- Big Bad: The main predator of the episode and thus the main antagonist.
- Death by Irony: It dies because of its one own massive size after it gets stranded, and later eaten by a group of Eustreptospondylus (note that it kills one of them in beginning of the episode).
- Downer Ending: Its death at the end of the episode is just as depressing as the death of the Postosuchus in the first episode.
- The Dreaded: It's the most feared creature of its environment, and the most powerful carnivore featured in the entire series. The series also contributed the fame and semi-mythical reputation earned by the Liopleurodon later in popular culture.
- Establishing Character Moment: Killing a Eustreptospondylus in the beginning of the episode is one of the most memorable scenes in the series.
- Lightning Bruiser: A fast swimmer despite its huge size.
- Prehistoric Monster
- Rule of Cool:
- Liopleurodon isn't known from remains as large as the animal depicted in the show.
- The entire introduction scene (epic as it may have been), wherein the Liopleurodon eats a Eustreptospondylus by leaping out of the water and grabbing it by the tail. Granted it's not impossible, but it has never been confirmed. Word of God states that it based on similar behavior done by orca whales.
- Sea Monster: Is actually depicted more or less as this.
- Slasher Smile: The way he's animated makes him look as though he's constantly sporting one of these. Taken even further, it fades when he ends up beached.
- Villain Protagonist: It's arguably the actual main character of the episode, and is the more memorable than the Ophtalmosaurus. Just look at how many more tropes have been listed for it! However, it is subverted by the fact that it's just a predator rather than actually evil.
A land-lubbing scavenger.
A small Jurassic shark, appearing again and again in the episode.
- Eats Babies
- The Nose Knows: They can smell blood. They're sharks. It comes with the territory.
- Threatening Shark: Mostly averted, as they are subservient to Liopleurodon, but they are threatening in their own right.
A seal-like plesiosaur.
A gull-like pterosaur.
Giant Of The Skies
The main protagonist of the episode, a large pterosaur.
- Babies Ever After: Implied in the book (and the documentary, albeit in a "blink-and-you-miss-it" sense) to show that his journey may not have been completely pointless:
Despite this ignominious end, the old male was a success. In his 40 years of life he probably sired several thousand offspring and it is likely that some of them were on this beach, competing and succeeding where he finally failed.
- Bad Ass Grandpa/Cool Old Guy: He flew halfway across the world and cheated death multiple times all because his sex drive was too much for him to ignore. The trip pretty much killed him, but you have to admit that doing something like that must have taken a lot of stamina. The book and "Prehistoric Planet" also imply that he's a literal example of the former (he may have had children and grandchildren).
- Bloodier and Gorier: His death is considerably more bloody and violent in the book (simply put, the rival males more or less try to tear him apart every time he attempts to land).
- Death by Sex: Inverted; he never gets the chance to mate and then he dies.
- The Determinator: He would've stopped at nothing to get to his mating grounds. And later, even when he's driven away and then slowly dying of starvation and heat stress, he's still calling for females to mate with him. He fails, but still. Possibly justified since he's being driven by instinct.
- Dying Alone: In the documentary. In the book, he's surrounded by other dead and dying Ornithocheiruses. Though granted that's not particularly good company.
- Early-Bird Cameo: The specimen the improbably giant size estimates were based on didn't get scientifically described until 2012.
- Foregone Conclusion: His death is shown right at the opening narration.
- Giant Flyer: 40 feet from wingtip to wingtip.
- How We Got Here: His dead body is shown in the opening narration and the Narrator announces to the viewers that we'll get to see the story of his last journey.
- Ptero Soarer: Though he's comparatively more accurate than the other pterosaurs in the series, he still skim-feeds and is far too clumsy in the air and on the ground.
- Rule of Cool: The producers chose the largest possible size estimate for this pterosaur to use in the show for this reason. In reality, a wingspan of 8 meters is more likely even for the large specimen the estimates were based on.
- Shoot the Shaggy Dog: Travels the whole world to mate, dies without mating a single time.
- Subverted in the book, which implies that his death wasn't completely in vain, as his offspring from past mating seasons were most likely on the beach as well.
- Spared by the Adaptation: He lives in the arena spectacular, though he does have a brief run in with some raptors.
- Starts with Their Funeral: The opening narration shows him dead.
A smaller pterosaur, appearing in the start of the episode.
- Early-Bird Cameo: The species of Tapejara (though now reassigned to Tupandactylus) used had not been published at the time the series aired.
- Giant Flyer: Smaller than the Ornithocheirus, but still large for a flying animal.
- Hero of Another Story
- Nice Hat: Well, its part of their head, but still....
- Noisy Nature: Justified, being a mating colony.
- Ptero Soarer: More so than most other depicted pterosaurs because it's proportions are utterly screwed, it's crest has weird ridges on it that make it look like some sort of fish fin, and it lives on the beach, eating fish, when even back then the idea that they were terrestrial omnivores with possible frugivore leanings was the most common interpretation.
- In the book, they're depicted as scavengers, being described as "combing the lagoons for carrion". This was unlikely in real life.
A herd-living dinosaur, appearing as the main large herbivore of the episode.
A large pliosaur, appearing for one scene, and having absolutely no effect on the plot whatsoever. We will include it anyway, because, well, you know.
A raptor, appearing for a small segment in Europe.
A small gregarious bird, shortly harassing the Ornithocheirus
A small armored dinosaur shown traveling alongside the Iguanodon
Spirits Of The Ice Forest
A small dinosaur, and the main protagonist of the episode.

A large amphibian living in Antarctica.
A large iguanodontian, appearing as summer guests to the territory.
Death of a Dynasty
- Action Mom: The mother.
- Bad Ass
- Battle Couple: Until the female drives the male away.
- Mama Bear: Woe betide the animal stupid enough to mess with her kids...
- More Deadly Than The Male: The female is larger and more aggressive than her mate.
- Scary Teeth: They're serrated and as big as steak knives, despite the fact T. rex didn't have serrated cutting teeth in Real Life.
- She Is the King: Tyrannosaurus rex translates to "tyrannical king of lizards", but the protagonist of the episode is a female Tyrannosaurus.
- Stock Dinosaurs
- Through His Stomach: Gender-flipped; the male courts the female by offering her a dead Triceratops. The narration indicates that the female will attack him if he doesn't do this. The meal pacifies her and makes her more willing to consider him a potential mate.
- Tyrannosaurus rex: Duh, who else would she be?
- The Unfavorite: One of the young is bullied by his siblings, and dies after a few weeks.
- Villain Protagonist: Averted. This is perhaps the most sympathetic, if not downright tragic T. rex ever put to film.
- The Worf Effect: The mother is killed by an Ankylosaurus.
A large herbivore, severely damaging the mother Tyrannosaurus
The main prey item of the Tyrannosaurus
Another main prey for the Tyrannosaurus
A tenacious mammal, and the only animal thriving in the harsh Cretaceous environment.
- Circling Vultures: Much of their behaviour borders on this.
- The Swarm: When there are enough of them.
- Science Marches On: Is depicted as a Tasmanian devil-like land dweller, when since then several studies have indicated that it was actually primarily semi-aquatic. Ironically, too, since it is used as an argument for mammal "opression" in the Mesozoic, when in reality it is an example of a higher diversity of mammal types in the Late Cretaceous.
- Swarm of Rats: In their behaviour.
- Zerg Rush: In a gag sequence in the Making Of special, against the Tyrannosaurus.
A large pterosaur, appearing shortly.
A large crocodilian, appearing shortly, but expanded in Prehistoric Park
and the book.

A small nocturnal carnivore, member of the group ancestral to both dogs and cats.
A large carnivorous whale, and the main protagonist of the episode.
A scavenger, appearing in a separate plotline of the episode.
A large, rhino-like animal, appearing along the Andrewsarchus
in the separate plotline
A basal relative to elephants, appearing as a potential prey item for the Basilosaurus
A small, early monkey, appearing in a small, plot-irrelevant role in the mangroves.
A small whale preyed on by the Basilosaurus
A small shark, referred to only as "shark" in the episode, and carrying only a minor role, mainly for The Worf Effect
Land Of Giants
A prehistoric rhino, though tall as a giraffe.
A predator, not closely related to hyenas, and the main antagonist of the episode.
- Angry Guard Dog: Has this appearance.
- Bad Ass : They are one of the biggest land carnivore of it's time and without doubt one of the fiercest.
- Butt Monkey: They never succeed at anything in this episode.
- Cool Versus Awesome: Their confrontation with the entelodonts. Hell, its so awesome, that it was actually the cover for the DVD release of Walking With Beasts. It seems as if it was the main point of the episode, and the indricotheres where just Supporting Protagonists.
- Dumb Muscle: reason for its extinction (not stated in-series)
- Hell Hound: They sure look like this.
- Meaningful Name : Hyaenodon literally means "Hyena tooth" though technically it isn't related to Hyenas.
- What an Idiot : It tries to defend it's prey from the entelodonts in a rather desperate act (pooping on it) in order to hide it's smell. Doesn't work at all. As weird as it is though it was based on real life fossil evidence.
- Who's Laughing Now?: One is shown chasing a lone young entelodont in the middle of the rain. It's not clear if it's the same Hyaenodon who was chased away by the entelodonts earlier. But then it slips on the mud.
A large relative to pigs, a scavenger in Mongolia.
The main prey item of the episode, a large relative of horses.
- Neck Snap: One of them is killed this way by a Hyaenodon.
- Fed to Pigs: The entelodonts take over a carcass of one.
- Mix-and-Match Critters: Walks like a gorilla, lives like a panda, has anteater claws on the front legs and hooves in the hind legs. Is related to horses and rhinos.
- Rule of Cool: Chalicotherium is not known from the place the episode is set in until later, so the show crew handwaves their chalicothere as a close relative of Chalicotherium that is yet to be discovered.
- Wolverine Claws: Though their main victims are trees. A chalicothere doesn't even use them when attacked by a Hyaenodon (it tries though).
A small carnivore.
- All Animals Are Dogs: Not much of a bear outside of its name.
- All There in the Manual: Referred to as a "bear-dog" in the episode, identified specifically as a member of Amphicyonidae (as more specifically as based on Cynodictis) on the show's website.
- Mama Bear: A mother charges face front against an indricothere to keep it away from her pups. While the indricothere is a baby, it's already several times the size of the mother bear-dog.
- Hero of Another Story: Its presence is entirely incidental.
Next Of Kin
Our earliest known direct ancestor, a bipedal ape living in Africa.
- Badass Grandpa / Handicapped Badass: Grey is grey-haired and blind in one eye, yet remains boss of the group for the better part of the episode. He's probably been on top for years, and the narration implies that he could have driven off the invading group if his own had not been recently depleted by malaria. He is also beaten by Hercules because the latter uses a branch as a weapon; Grey prevails in an earlier fight with their bare hands.
- Bad Boss: Grey is also quite the ass to his females and to Hercules, until the latter kicks his ass and takes over the group. Rather ironically, he is the only one to pay any attention to Blue before the ending, as well.
- Butt Monkey: Blue. Seriously, his mother dies of malaria, and he is nearly left behind when a rival Australopithecus gang takes the group's territory by force. Even the other australopithecine children don't want to play with him. Also, the group as a whole, to an extent.
- Chekhov's Skill: Hercules uses the skills used to drive an Ancylotherium away to chase away vultures later.
- Chekhov's Gun: Hercules also keeps in his hand the branch used to dig for tubers earlier while chasing off the vultures, and it becomes an effective weapon when he fights Grey over the carcass later.
- Cool Old Guy: Grey.
- Da Chief: Grey.
- The Dog Bites Back: To the Dinofelis, eventually. Also, Hercules to Grey at the dead zebra.
- Everything's Better with Monkeys: Though they are not technically monkeys.
- From Nobody to Nightmare: Mankind's origins were humble and far from the top of the food chain. Some might see the scenes where the australopithecines get a taste of meat and drive a Dinofelis away later as a Start of Darkness...
- Humans Are Special: Only episode starring hominids, only one where the main characters get "personal" names.
- Klingon Promotion: Hercules fights Grey to become the top male in the group.
- Mama Bear: Bubbles, after finding out her baby was accidentally left behind and is at the mercy of the Deinotherium, instantly goes back to rescue him. Granted, it doesn't work, but still...
- Mix-and-Match Critters: Of humans and chimpanzees.
- Rule of Cool: Praeanthropus may be the correct name for this species.
A saber-toothed cat, and the main antagonist of the episode.
- Bad Ass : It is basically a super sized leopard, with saber teeth, and more muscular body. Our ancestors learn who is the top predator of the savannah in a hard way.
- Cats Are Mean: Averted. It's presented as just a predator trying to feed itself, although still a constant danger to the Australopithecus clan.
- Hero Killer : It is the main predator of the Australopithecus.
- Panthera Awesome: Undeniably.
- Rule of Cool: The idea that Dinofelis was a specialized primate killer is merely conjectural.
A large elephant relative.
- Ax-Crazy: A musth-striken young male encountered by the australopithecines is one of the only creatures that can be described as this in the series.
- Bad Ass
- Dumb Muscle
- Honorable Elephant: Completely averted. They are not the least honorable.
- Rhino Rampage: It is an elephant relative, but its behaviour fits.
The last surviving chalicothere. It lacks the anteater-like claws of previous ones and serves a small role in the episode.
Smilodon (sabre-toothed cat)
The last and largest of the saber-toothed cats, and the main protagonist of the episode.
- Artistic License – Paleontology: Their behavior, which was bluntly copied from extant African lions. Most notably, the females are seen chasing down Macrauchenia, being able to do sharp turns while running. Smilodon was an ambush predator that could only run in short bursts of speed; its short tail would have made it very unbalanced in a high speed chase.
- Smilodon males and females were similar in size and built, making the lion harem-style pack even more unlikely (a wolf-like social life has been proposed based on remains from Rancho La Brea, but it is controversial still).
- Bad Ass : As expected from the biggest, baddest sabertooth cat that ever lived, even if the sabers were fragile compared to other big cat fangs. Special mention goes to Half-Tooth.
- Bad Ass Grandpa: Half-tooth.
- Bad Ass Crew : The pride/pack is the most efficient killing machine in the plain of its era. However it's later zig-zagged due to the fact it doesn't do much to defend their young from the brothers and quickly runs away without giving a fight when their leader is killed by a Megatherium.
- Eats Babies: Half-tooth eats a Macrauchenia baby.
- Earn Your Happy Ending : Half-Tooth gets one after fighting the two brothers.
- Downer Ending : For the brothers, both died in the end after their short violent reign.
- Not So Different: The "villain" brothers are just doing what Half-Tooth did years ago (and eventually does again, when they are reduced to one).
- Papa Wolf : In the beginning of the episode Half-Tooth chases away a pair of terror birds attempting to eat one of its babies.
- Panthera Awesome
- Spared by the Adaptation: The second brother in the book, who simply runs away after his brother is dead. In the show, he is mortally injured by Half Tooth and devoured by the terror birds.
- Siblings in Crime: The two brothers that drive Half-tooth from his pride.
- The Worf Effect: Half Tooth is driven away by the brothers. Later turned around when a Megatherium kills one of them.
- Would Hurt a Child: The brothers.
Phorusrhacos (terror bird)
A large flightless bird, and the previous top predator of South America. One of the most severely underrated predators of the entire series, being depicted as a cowardly scavenger instead of the lightening-fast apex predator capable of competing with any mammalian carnivore it really was.
- Artistic License – Paleontology: They are seen 700,000 years after their supossed extinction; this particular genus died out during the Miocene. And it would have had no trouble competing with sabretooths, as it was much faster and hunted faster prey.
- Bad Ass : It may have been dethroned as arch-predator maybe (not the case in Real Life), but as the Macrauchenia learns the hard way, their killing skill is still very effective.
- Carnivore Confusion: Depicting them as scavengers, making less sympathetic than the equally carnivorous Smilodon. This despite the fact it was not a scavenger (it couldn't be even if it tried) and was just as good a predator as its rival in-universe.
- Circling Vultures: The wounded brother is pursued by phorusrhacids after he is usurped. Guess how it ends for him....
- Feathered Fiend: And considerably more fiendish in Real Life.
- Lightning Bruiser: It appears out of no where to kill a young Macrauchenia.
- The Worf Effect: Most of their screentime involves them being chased off by Smilodon. Science Marches On, since it would have been more than capable of killing the adult, especially when having strength in numbers. They were also much faster than the slow-moving cats.
The standard prey animal of the episode. A large grass-eater.
- Butt Monkey : Serves the episode simply as prey for Smilodon and terror birds. (And possibly the Megatherium).
- Fragile Speedster: Speed is its main defense and it is well built for quick turns. Once it gets caught however, it has no way to fight back.
- Mix-and-Match Creatures: A llama-like animal with a tapir-like head. Ironically, while both existed in South America in this time and still do today, they are not related to South American native Macrauchenia, but are recent immigrants from North America instead.
- What Measure Is a Non-Cute?: The approach to keep the Smilodon sympathetic, is to make this completely dull, and hard to sympathize with.
A large sloth, very strong.
A giant armadillo relative.
Oh, come on, you know this one!
The main protagonist of the episode.
A giant deer with a set of equally giant antlers.
You ought to know this one as well. Appears in a minor role.

The main predator of the segment, a giant lobe-finned carnivorous fish.
Shown as one of the first reptiles and our first fully terrestrial ancestor.
A Giant Spider
, and the largest that ever lived. Note that this was probably the most severe case of Science Marches On
on behalf of the producers: They based this creature on the fossils of a creature called Megarachne
, but late in production, it was found that this was actually sea scorpion. The name of the spider in the show was changed to Mesothelae (a group of basal spiders), and they decided to leave it in, though evidence for such a creature doesn't exist.
A giant dragonfly and a secondary predator of the segment.
- Always a Bigger Fish: Steals the Petrolacosaurus from the Mesothelae spider. Then gets its eaten by the Proterogyrinus during the storm.
- Bad Ass : As the Narrator puts it they are "the Queen of the sky" of the carboniferous era
- Big Creepy-Crawlies : More like Big creepy flyers actually.

- Stock Dinosaurs: Of the non-dinosaur variety.
- Tear Jerker : It lose one of it's eye and starving to defend it's eggs and yet at the end of the story it tries to kill and eat the weak one due to it's hunger. As the narrator put it :
"One adult is driven by hunger and desparation...the mother."
A carnivorous amphibian harassing the Dimetrodon

A primitive ceratopsian
A famous little meat eater.
A small birdlike dinosaur.
The Asian answer to T.Rex.
A large, scavenging pterosaur.
- All There in the Manual: Only identified on the (now-removed) official website. There was a picture of it there, too. It looked like a recolored Pteranodon.
- Circling Vultures: Subverted; a flock of them circle over Nigel at one point, but nothing sinister comes of it.
- Palette Swap: Seems it suffered the same fate as its cousin Quetzalcoatlus.
The Land of Giants
The biggest plant eating dinosaur of all time.
- Badass: When we say "biggest land animal of all time", we mean it.
- Dumb Muscle: Like most sauropods.
A huge meat-eater.
- Badass: It certainly lives up to its name.
A famous flying reptile.
- Breakout Character: It managed to make it into "Sea Monsters" and is the only animal from "Chased by Dinosaurs" to do so.
- Giant Flyer: Not giant giant, but still big enough to qualify.
- Irony: Eats fish, almost gets eaten by a fish (Xiphactinis).
- Misplaced Wildlife: In "Chased by Dinosaurs", wherein it's seen in South America. Rectified in "Sea Monsters".
- Nice Hat: Its head crest is basically one of these.
- Ptero Soarer: Though to BBC's credit, this is the most accurate (for its time) pterosaur depicted in the series.
- Stock Dinosaurs: Having failed to appear in "Walking With Dinosaurs", it made its debut here.
- Team Pet: One becomes this for Nigel's boat crew in "Sea Monsters", where Nigel feeds it a fish and it sits on the boat with them. It seems to take a liking to the crew, seeing as it seems genuinely frightened when it seems that Nigel's going to be devoured.
A giant crocodile.
Walking With Dinosaurs 3 D
The protagonist, a Pachyrhinosaurus
- Adaptational Badass: In the video game, where he even wins against Scowler.
- Big Damn Heroes: He pulls this off in the end, leading the herd to save Scowler from the Gorgosaurus pack.

- Buffy Speak: Calls the Chirostenotes "skinny necked pecky things".
- Chekov's Gun: You see the hole in his frill the Troodon made eariler? He later uses it to break Gorgon's arm and finish him.

- Use Your Head: As expected from a ceratopsian.
- Victorious Childhood Friend: With Juniper.
The protagonist's friend, an Alexornis

- The Narrator: Of the movie. He often shares the narrating with Patchi, though.
- The Mentor: To Patchi.
- Running Gag: While talking about something, he'll see bugs flying and quickly eats them.
- Seldom Seen Species: Enantiornithes are rarely depicted on screen, let alone Alexornis
- Toothy Bird: Although somewhat realistic, since many similar birds had teeth and all, Alex's design is seemingly more oriented towards cartoony bird appearences, having a "beak" with teeth instead of the feathered snout of known enantiornithe snouts.
- Undying Loyalty: To Patchi.
- What the Hell, Hero?: He couldn't believe it when Patchi tells him to let him die, so he scolds him and says that if he's going to die...then he should die for something worth living for (his love for Juniper).
Patchi's Love Interest
Patchi's older brother.
- Big Brother Bully
- Big Brother Instinct: When he sees Patchi return after kicking him out of the herd, the first thing he does is warn his little brother to keep away from the attacking Gorgosaurus and get to safety.
- Break the Haughty: When he attempts to fight the Gorgosaurus at Ambush Alley, getting himself nearly killed as a result. Alex lampshades this and nicknames Ambush Alley "Scowler's Folly".
- Catch Phrase: "Eat my dust!"
- Death by Adaptation: In the video game, although he is not referred to by name. After getting beaten by Patchi, he gets killed by Gorgon.
- Dumb Muscle
- Drunk with Power: As bad as he is to start with, he gets worse after becoming leader of the herd.
- Hate Sink: Especially during his Kick the Dog moment towards Patchi. Seeing Gorgon tear him apart after that is somewhat satisfying.
- Heel-Face Turn
- Jerk Ass
- Jerk Jock
- I Have No Brother: He says this to justify his reason to not listen to Juniper when she begs him to help Patchi. But then immediately subverted when Gorgon is mauling him.
- Kick the Dog: After he mauls Patchi during their fight, he kicks him out of the herd and refuses to let Juniper help him.
- Use Your Head
. Supposedly the Big Bad
of the film.
- Badass: He snatches a freakin' pterosaur from the air. Not to mention he was able to handle both Bulldust and Scowler easily.
- Berserk Button: Apparently, due to his eyes narrowing, he does not like Patchi calling him "tiny arms".
- Gender-Blender Name: Sort of. The word "gorgon" generally applies to female monsters.
- Genius Bruiser: He is intelligent as he is powerful and fast.
- Kick the Son of a Bitch: Him attacking Scowler and nearly killing him at the climax of the film can be seen as this, especially considering how the latter had just left his own brother to die in a ditch.
- Lightning Bruiser
- Predators Are Mean: Subverted. He is never depicted evil or malicious, but rather just hungry and wanting to feed his pack.
An older Pachyrhinosaurus
and the leader of his herd. He's also Patchi and Scowler's father.
A trio of lesser antagonists.
- Circling Vultures: Serve this purpose at one point.
- Giant Flyers: Though the movie shows that they're just as competent on the ground as they are in the sky.
- Hates Being Touched: The one in the middle hates it when the one on the left sidles up to it and lets it know with a squawk.
- Ptero Soarer: They do have a level of accuracy to them (they were designed by pterosaur expert Mark Witton, after all), but there are still some mistakes here and there; they have pointy wing tipsnote , their wings bend the wrong way when on the groundnote and their diet is shown to include fish and carrionnote
- Quirky Mini Boss Squad
- Terrible Trio: Though they used to be a quartet before Gorgon got his jaws on one of them.
