about the prosauropod/sauropodomorph...

The classification of Herrerasaurus was unclear because it was known from very fragmentary remains. It washypothesized to be a basal theropod, a basal sauropodomorph, a basal saurischian, or not a dinosaur at all but another type ofarchosaur. However, with the discovery of an almost complete skeleton and skull in 1988,[3] [4]  Herrerasaurus has been classified as either an early theropod or an early saurischian in at least five recent reviews of theropod evolution, with many researchers treating it at least tentatively as the most primitive member of Theropoda.[5]

It is a member of the Herrerasauridae, a family of similar genera that were among the earliest of the dinosaurian evolutionary radiation.
