The Coelurosaurs tracks are estimated to be 170 million years old. They were found in 1950 in the eastern Mojave by James Evans. He identified some of the impressions in the sandstone as the footprints left by small bipedal dinosaurs called coelurosaurs and took photographs of the site.

The coelurosaurs tracks are estimated to be 170 million years old. They were found in 1950 in the eastern Mojave by James Evans. He identified some of the impressions in the sandstone as the footprints left by small bipedal dinosaurs called coelurosaurs and took photographs of the site.

Coelurosauria from Greek, meaning “hollow-tailed lizards” is the clade containing all theropod dinosaurs more closely related to birds than to carnosaurs.

The studying of anatomical traits in coelurosaurs indicates that the last common ancestor had evolved the ability to eat and digest plant matter, adapting to an omnivorous diet, an ability that could be a major contributor to the clade’s success.

Fossil evidence shows that the skin of even the most primitive coelurosaurs was covered primarily in feathers. Fossil traces of feathers, though rare, have been found in members of most major coelurosaurian lineages.

Most coelurosaurs also retained scales and scutes on some portion of their bodies, particularly the feet, though some primitive coelurosaurian species are known to have had scales on the upper legs and portions of the tail as well.
