Carnotaurus
Carnotaurus was an unusual meat-eating dinosaur that lived during the mid-Cretaceous period, 113 to 91 million years ago. It had knobby horns over its eyebrows, which were used for head butting and mating rituals, and four-fingered “hands” with a backward-pointing spike. While most dinosaur fossils have been found in North America, Carnotaurus was discovered in Argentina, South America and quite recently (1984) by José F. Bonaparte. He found only a single fossil, but it was so well preserved that rough bumps were visible on its skin.

Styracosaurus
Styracosaurus was a plant-eating dinosaur that lived during the early Cretaceous Period, 65 million years ago. It was an ancestor of Triceratops, with one large horn on its snout, a small horn above each eye, and a spiked neck frill for protection from predators such as T. rex. Like Triceratops, Styracosaurus used its sharp beak to cut leaves from low-growing foliage, such as cycads, and its powerful jaws to chew the tough leaves. A large bone bed with approximately 100 Styracosaurus fossils indicates that Styracosaurus traveled in herds. |

Triceratops
Triceratops was a plant-eating dinosaur that lived during the late Cretaceous Period, 65 million years ago. It was a descendant of Styracosaurus, with horns on its snout and eyes, and a spiked neck frill. Triceratops could open its jaws sideways to gather foliage by rotating the joint between its head and neck. Fossil evidence indicates that the underside of the neck frill contained a dense network of blood vessels that was used to cool the dinosaur in much the same way elephants transport blood to their ears to radiate heat. |

Tyrannosaurus rex
Tyrannosaurus rex was a large, two-legged, meat-eating dinosaur that lived in the late Cretaceous Period, 65 million years ago. Scientists know more about Tyrannosaurus than any other predatory dinosaur. Tyrannosaurus had a bone-crushing bite and often preyed upon plant-eating dinosaurs, and its stomach could hold more than half a metric ton of meat. The frill of a Triceratops was found in the fossilized dung of a Tyrannosaurus.
