Reptiles

Reptiles are a cold-blooded vertebrate animal class that regularly sheds their outer layer of skin, yet are also very similar to birds (in fact, the crocodile is more closely related to a bird than to a lizard). Reptiles are not as old as fish, with the earliest reptile on record emerging 315 million years ago, but they were the dominant class during the Mesozoic age until the extinction of the dinosaurs. Like birds, reptiles are an air-breathing class with many of its species laying eggs instead of giving birth to live young. In fact, out of all the reptiles, the only species to give birth to live young are boas and pythons. Being cold-blooded without the ability to regulate their internal temperature, Reptiles become inactive during the cooler times of the year.

Stegosaurus
Size comparison drawing with dimensions of a Stegosaurus and an average human

Stegosaurus was a Late Jurassic (155-150 Mya) herbivorous quadrupedal dinosaur known for its array of upright plates on its back and strong spiked tail. Heavily built with short limbs, a small head, and large body, Stegosaurus was a defensive dinosaur that likely foraged for twigs and low hanging fruits.

Spinosaurus
Comparison drawing of a Spinosaurus and a human with dimensions for height and length

Spinosaurus was a large carnivorous Cretaceous period (112-93.5 Mya) dinosaur characterized by its large thin back spikes. A giant predator on both land and water, similar to the present day crocodile, fossils prove that the Spinosaurus was as larger or larger than the Tyrannosaurus Rex.

Triceratops
Illustration comparing the size of a Triceratops to a human with dimensions for height and length

Triceratops were three-horned herbivorous dinosaurs that roamed western North America in the late Cretaceous period (68-66 Mya). Combined with a shield-like head plate, the horns of the Triceratops were likely used to protect them from predators and may have also been used for mating rituals. The Triceratops had a length between 26’-29.5’ | 7.9-9 m and stood 9.5’-10’ | 2.9-3 m tall.
