Join Ken McKeighen and Ken Boorman as they discuss what was likely one of the first dinosaurs.About 230 million years ago–give or take a few million years–the first dinosaurs evolved from a population of Archosaurs the “ruling lizards” that shared the earth with a host of other reptiles, including therapsids and pelycosaurs. As a group, dinosaurs were defined by a set of (mostly obscure) anatomical features, but to simplify matters a bit, the main thing that distinguished them from their archosaur forebears was their erect posture (either bipedal or quadrupedal), as evidenced by the shape and arrangement of their hip and leg bones.
