Unaysauridae
Unaysauridae is a clade of basal sauropodomorphs from the Late Triassic of India and Brazil. Diagnosis and systematics. Unaysauridae was defined by Müller "et al." (2018) as the most inclusive clade including "Unaysaurus tolentinoi", but not "Plateosaurus engelhardti" nor "Saltasaurus loricatus". Members of Unaysauridae are diagnosed by a substantially expanded cranial part of the medial condyle of the astragalus, as well as a promaxillary fenestra. Unaysauridae is sister to Plateosauria, more derived than "Nambalia", "Thecodontosaurus" ISI R277, "Pantydraco", and "Efraasia". "Unaysaurus" and "Jaklapallisaurus" had previously been assigned to Plateosauridae by prior authors.
