et al. (2004) noted that theropod tracks and fossils of an unnamed herrerasaur genus are known from the Lower Stubensandstein. Procompsognathus appears...

bauplan, Cau (2018) found in the parsimony analysis a polytomy between herrerasaur-grade taxa, Sauropodomorpha and the controversial Ornithoscelida. The...

It dates back to the middle Norian. Theropod tracks and an unnamed herrerasaur genus are known from the Lower Stubensandstein. Cyclotosaurus Metoposaurus...

(lizard-hipped) dinosaur, a more advanced theropod, and a close relative of the herrerasaurs, but its taxonomy has been in dispute because only fragmentary remains...

Cau (2018) and Novas et al. (2021) considered Tawa a non-herrerasaurid herrerasaur, although the first study placed Herrerasauria outside Dinosauria and...
