Buitreraptor


Unable to catch dinosaurs because of teeth with no grooves buitreraptor probably ate insects or small mammals, maybe even eggs. Its feathers were probably used to keep it warm, like the feathers on troodon.

Dromaeosaurus


Like all other raptors dromaeosaurus was quick, and had a curved claw on his foot. Its sharp little teeth were used for slicing through prey while its claws kicked the large herbivore it attacked.

Gigonotosaurus


A smaller relative of gigonotosaurus was carcharadontosaurus who was not smaller by much, they were almost the same size! Gigonotosaurus hunted the second largest animal that ever lived, ARGENTINOSAURUS! for breakfast.

Carcharadontosaurus


The teeth of carcharadontosaurus reminded the scientist who found it of shark teeth. Its relatives maupusaurus and gigonotosaurus were i little larger, but not by much.

Syntarsus


Syntarsus looked a lot like coelophysis. It was probably about the same size as a chicken. It lived in the Triassic in Zimbabwe. It ate meat, probably small lizards and insects, like composognathus who lived in the Jurassic.

Coelophysis


It was a small dinosaur, only the size of a chicken. It lived in the Triassic, in New York and Arizona. This little dinosaur surprisingly ate crocodiles! Scientists found crocodile fossils in the stomach remains of some Coelophysis.

Herrerasaurus


One of the earliest dinosaurs, herrerasaurus was a carnivore witha hip that resembled both lizard hipped dinosaurs and bird hiped dinosaurs. (Saurischians and ornithschians). Its name means Herrera's lizard.

Eoraptor


A strange early dinosaur, it didn't have the same hips as other dinosaurs. This early carnivore would have preyed on insects and other small animals. It lived around the mid-triassic. So far it is the earliest dinosaur we know about.
