The First Dinosaur - Eoraptor

Some time during the middle Triassic period, about 230 million years ago, the very first dinosaurs evolved from their archosaur ancestors.

Befitting its early place on the dinosaur family tree, Eoraptor was only about two feet long from head to tail and weighed five pounds soaking wet, but it compensated for its puny size with sharp teeth and grasping, five-fingered hands.
