Euparkeria capensis

Middle Triassic of South Africa (245-230Ma). Discovered in early 1900s, described in 1913. The hindlimbs were slightly longer than the forelimbs, so some reconstructions have depicted it as facultatively bipedal, although this is uncertain and will be tested in this project.

It was more “primitive” than the split between the dinosaur and crocodile lineages, so it was not an archosaur, but an archosauriform; widely considered to be close to the anatomy of the common ancestor of Archosauria.
