Animals

A predatory tyrannosaur. Instead of building dinosaur nests, it lays its eggs in trios, allowing for three young ones instead of one to hatch at a time. Its young can hunt in packs. Be warned, as adults may resort to cannibalism out of desperation if their hunger reaches an extreme threshold.

A ceratopsian. Its babies hatch extremely small and use different enrichment items from their parents due to their small size. They are also much easier to contain.

The largest turtle known to have existed. Exceptionally long-lived, it will take quite some time to die of old age in your zoos.

A theropod from north Africa, it exceeded even the mighty Tyrannosaurus Rex in length. It lived in mangrove-dominated tidal flats, making it compatible with the Wetlands and Coastal biomes.

A large extinct shark that develops quickly. It grows to sizes exceeding those of the great white shark. Cretoxyrhina mantelli is also known by its common name, the Ginsu shark. 

A massive basal alligatoroid. It has an intense rivalry with the Albertosaurus. If they are placed in the same exhibit, they may even duel each other! It can also rampage, and it can crossbreed with Zoo Tycoon 2: Extinct Animals' Deinosuchus hatcheri.

A brainy troodontid. Despite its small size, it is capable of rampaging, so be careful not to draw its ire.
