History Characters / PrehistoricPark

* DemotedToExtra: While Terrance shares focus with his sister in the first episode, the later focus chiefly on the more active and troublesome Matilda while regalating Terrance to the background.

Nigel Marven returns to play as himself, this time as an owner of a prehistoric wildlife park. He travels to the past in order to bring extinct prehistoric creatures back to life.

* BadassBookworm: 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 [[TimeTravel time-traveling]] [[Series/CrocodileHunter Steve Irwin]].
* TheKirk: Plenty snarky, thought of a more jovial than sassing nature. He is prone to emotional and logical choices in equal measure.
* PragmaticHero: In the final episode he nearly sacrifices Matilda to the ''Deinosuchus'', the situation being that grave that even Nigel is willing to take the very likely chance Matilda will be eaten.

The 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.

* ButtMonkey: Usually on the receiving end of the whatever bad things that the prehistoric creatures brought, mostly from the Titanosaurs.
* CoolOldGuy: He is a wise adviser to Nigel.
* TheMcCoy: The most emotional of the main trio, especially when he has to deal with all the animals Nigel keeps bringing in.
* OnlySaneMan: 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.

The head-vet of the park. Tasked with treating the injured animals and looking after their health.

* HospitalHottie: Downplayed. She's a good-looking woman working as a veterinarian, but her attractiveness isn't in focus.
* TheSpock: The calmest of the main trio and the one working in a hard science the most.
* TeamMom: Especially in the sixth episode where she had to nurse the surviving baby ''Smilodons'' because their mother's milk had run out.

A Kenyan conservationist with a lot of expertise in big cats. She joins Nigel on the second trip to the early Holocene in South America to help him find potentially the last sabretoothed cats on Earth.

* FriendToAllLivingThings: Just as much as Nigel. All the more heartbreaking when they couldn't save the sabretooth cubs.
* GuestStarPartyMember: She joins in on the expedition to try and save the last ''Smilodon'' left in the world.
* PantheraAwesome: Some of her expertise, having done field work with lions, leopards, and cheetahs in Kenya.

A teenage ''Triceratops'' Nigel rescued from a ''Tyrannosaurus'' attack, becoming the park's very first animal.

* DemotedToExtra: Other than his introduction episode, he's had only minor cameos.
* PintSizedPowerhouse: Theo starts out as one of the smaller dinosaurs do to his young age. But he begins to grow rather quickly after his debut.
* TemperCeratops: A combination of territorial instincts and teenage hormones mean that Theo develops an aggression problem. The zookeepers deal with by using tires and PVC to disguise a tractor as another ''Triceratops'' and using it to stage fights with Theo; this way, he can blow off steam in a controlled manner by locking horns with and chasing off a rival and becomes less prone to taking out his nerves on scenery and zookeepers.

A large flock of man-sized ostrich-like dinosaurs from the Late Cretaceous that prove to adjust quite well to the present, even becoming the first animals to reproduce at the park.

* ArtisticLicensePaleontology: They're depicted as scaly and semiaquatic -- the real animals were feathered and fully terrestrial.

[[folder:Terence and Matilda]]

[[caption-width-right:1000:Terence on the left, Matilda on the right]]

A pair of ''T. rex'' siblings Nigel managed to bring back from the Cretaceous seconds before the asteroid collided. Brought back as juveniles, their fierce natures and rapid maturation make them difficult for the keepers to handle.

* ArtisticLicensePaleontology: They're significantly more slender as adults than ''Tyrannosaurus'' were in real life, barely changed from their juvenile forms.
* ADayInTheLimelight: Terence gets a whole subplot to himself in Episode 5, revolving around him being seriously injured after a fight with his sister.
* [[BigBrotherBully Big Sister Bully]]: Matilda is established as one since the end of the first episode, at first domineering over Terence and later outright trying to kill him. Even the narrator notes how Matilda's hostility towards her brother only seems to grow.
* ButtMonkey: Terence is the second biggest ButtMonkey in the series (the other being Bob), given how much abuse he takes from his sister, nearly getting killed at one point.
* CainAndAbel: A fight between the siblings ends with Matilda nearly killing Terrance. Nigel separates them afterward.
* DemotedToExtra: While Terence shares focus with his sister in the first episode, later ones focus chiefly on the more active and troublesome Matilda and relegate Terence to the background.
* {{Jerkass}}: Matilda, as much as an animal can realistically be one, given that she's far more ill-tempered and confrontational than her brother.
* FluffyTheTerrible: They're both ''Tyrannosaurus rex'', one of the most revered (and feared) dinosaurs in history. Nigel decides to give them the names... Terence and Matilda.
* SiblingRivalry: Constantly fight to the point that the park staff had to separate them. Culminates in Episode 5, in which Matilda seriously injures Terence in a fight.
* TeensAreMonsters: Taken very literally with Matilda, who is a raging teenage ''T. rex'' that tries to attack anyone that crosses her path, including her own brother.
* TerrifyingTyrannosaur: Matilda grows up to be a nasty ''T. rex'', attacking her brother in a dispute which leads to the ''T. rex'' siblings being separated. By the end of the series, she becomes the main antagonist when the titanosaurs break through her enclosure, allowing Matilda to go on a rampage through the park.

[[folder:Terence and Matilda's mother]]

An unnamed female ''Tyrannosaurus'' who is, of course, the mother of Terence and Matilda. Unlike her children however, she doesn't survive long enough for Nigel to rescue her.

* ArtisticLicensePaleontology: Just like her children and the other ''T.rexes'' in the show, she's a lot slenderer than the real thing.
* HandicappedBadass: ''After'' getting gored in the left thigh by a ''Triceratops'', she manages to hunt and kill an ''Ornithomimus'' (a species of dinosaur that usually runs too fast for even a ''healthy T.rex'' to catch) to feed to her young, and when a rival male ''T.rex'' attacks Terence and Matilda, the still-injured mother fights the male before he overpowers and kills her.
* MamaBear: She defends her young from a rival male despite being injured, but unfortunately she loses both the battle and her life.
* WorfHadTheFlu: She was killed by the male because of the leg injury she already had.

A lone female woolly mammoth Nigel discovered mourning its dead sister (killed by prehistoric human hunters) and seriously injured (by the same hunters). At the park, she is adopted into a herd of modern African elephants.

* ADayInTheLimelight: Aside from her debut, Episode 6 had her briefly go toe-to-toe with Matilda.
* GentleGiant: She's about as sensitive and sweet-natured as a giant hairy elephant-like creature can get.
* HonorableElephant: She's a GentleGiant and very calm around her keepers. She was found by Nigel wounded but refusing to leave the body of her dead sister and is given a lot of sympathy.
* MamaBear: She once rushed to defend a baby elephant from Matilda.
* TooUnhappyToBeHungry: Martha the mammoth loses her appetite after she's brought to the park. The zookeepers first assume they're feeding her the wrong kind of plants, but then they realize she's sad because she's a herd animal kept in solitary confinement. They introduce her to a herd of African elephants, which brings her appetite back.

A giant, hairy, one-horned Ice Age rhinoceros brought back by Nigel during a return trip to the Pleistocene.

* AnimalStampede: Is seen fleeing the approach of Matilda alongside the ''Ornithomimus'' flock.

[[folder:The ''Microraptor''s]]

A flock of crow-sized, four-winged raptor dinosaurs from Early Cretaceous China.

* RaptorAttack: Fossilized melanosomes in the feathers of a ''Microraptor'' fossil suggest it was completely black in color, instead of being largely white like in the show.

The park's resident sauropods, nine individuals of an unidentified species. Brought back alongside the ''Microraptor''s during a volcanic eruption, their massive size makes them a major source of headaches for Bob.

* GentleGiant: Despite their size, they're not really that dangerous. [[spoiler:Unless they are spooked]].
* TheMillstone: Due to their size, strength, and obliviousness, they frequently cause trouble for the park.
** Their first breakout prevents Bob from hearing what size cage Nigel needs for the terror birds.
** They also demolish part of the Bug House, setting Bob back a bit on his schedule.
** {{Averted}} in regards to the breakout, though: that was more the ''Troodon'''s fault. Instead, they fill the role of TheMillstone by knocking over the trees Bob is planting as future food for them.
* MundaneUtility: In one episode, one of them is used to tow a stalled truck through the time portal by leading it with potential gastroliths. Who needs a tow truck when you have a dinosaur?
* NoNameGiven: Their species is never stated in series, as at the time the series aired, no sauropods were known from their time and place. Since then, three species have been identified: ''Dongbeititan'', ''Liaoningotitan'', and ''Ruixinia'' (although none are true titanosaurs).

[[folder:The Sabertooths]]
Two individuals of the famous sabertooth cat ''Smilodon'' (specifically the South American variation, ''Smilodon populator''). One is an older female that recently lost its cub and the other is a young bachelor male.

A giant, flightless, carnivorous bird, likely of the species ''Phorusrhacos'', rescued by Nigel during his first trip to Pleistocene South America.

* EscapeArtist: At the park, it has a habit of managing to get out of its enclosure. You'd think a ten foot tall carnivorous bird would be a problem, but see below.
* FeatheredFiend: Subverted. It is a big and potentially dangerous predator, but its behavior is downright placid once it's taken to the park.
* OutOfFocus: Though "Saving the Sabretooth" is promoted as being about Nigel saving the two apex predators of prehistoric South America, the terror bird gets little screentime and is quickly caught while most of the episode focuses on Nigel and Saba tracking down the last of ''Smilodon''. It does get a bit more focus in the final episode though.

A ''Pulmonoscorpius'', ''Meganeura'', and ''Arthropleura'' brought back from the Carboniferous and kept in a special, climate-controlled bug house with a high-oxygen atmosphere. They're the most ancient creatures kept within the park.

* BigCreepyCrawlies: A scorpion the size of a cat, a dragonfly with the wingspan of an eagle, and a millipede about two meters long. Notably, the ''Arthropleura'' manages to win the sympathy of the insectophobic Bob simply because it was just that big that it loses its creepy factor.

A gigantic alligator capable of killing and eating dinosaurs. It is the last animal that Nigel intentionally retrieves.

* ArtisticLicensePaleontology: It's at least a third larger than the largest known real life specimen, and appears even bigger than that in the scene where it eats a ''Nyctosaurus''.
* NeverSmileAtACrocodile: An alligator ''big enough to eat dinosaurs''.

A small and highly intelligent theropod dinosaur that becomes a stowaway from the final mission.

* ArtisticLicensePaleontology: It's depicted with only a thin feathered coat. The real animals are believed to have had a full covering of complex feathers.
* HungryMenace: How did it get into the park? [[spoiler:It snuck on the jeep to eat the leftover ''Deinosuchus'' bait and was still in it when Nigel returned to the present]].
* RaptorAttack: Slit pupils, pronated hands and only sporting a very thin coating of fuzz (making it look practically scaly anyway).
* UnwittingInstigatorOfDoom: [[spoiler:It's the reason the mass breakout in the final episode happens: after stowing away on Nigel's jeep (it was eating the leftover bait meat), it attacks Bob, almost causing him to collide with a titanosaur. The spooked sauropod promptly runs off, smashing open every exhibit it comes by]].

* FeatheredFiend: Subverted. It is a big and potentially dangerous predator, but its behavior is downright placid once its taken to the park.
