Common Dinosaur Types

Tyrannosaurus rex was one of the largest meat-eating dinosaurs that ever lived. Everything about this ferocious predator, from its thick, heavy skull to its 4-foot-long (1.2-meter-long) jaw, was designed for maximum bone-crushing action.

The Triceratops is easily recognized thanks to the three horns found on its face as well as its large body and the unique frill around its head. The name ‘Triceratops’ comes from the Greek language, with ‘tri’ meaning three and ‘keratops’ meaning horned face.

Stegosaurus was a large, plant-eating dinosaur that was about the size of a bus and carried around two rows of bony plates along its back that made it appear even bigger.

Velociraptor comes from the Latin words "velox" (swift) and "raptor" (robber or plunderer). A member of the Dromaeosauridae family of small- to medium-sized birdlike dinosaurs, Velociraptor was roughly the size of a small turkey and smaller than others in this family of dinosaurs.

Plesiosaurs were large, marine reptiles from the Mesozoic Era that ranged in size from 8-46 feet long (2.5-14 m). They had four flippers, sharp teeth in strong jaws, and short, pointed tails. Plesiosaurs may have evolved from the Nothosaurs or Pistosaurus, a mid-Triassic reptile.

Pachycephalosaurus; (meaning "thick-headed lizard," from Greek pachys "thick", kephale "head" and sauros "lizard") is a genus of pachycephalosaurid dinosaurs. It lived during the Late Cretaceous Period (Maastrichtian stage) of what is now North America. It was an herbivorous creature which is primarily known for its thick skull which was believed to be used in intra-species combat.
