Descripción
Some of the oldest known dinosaurs and the first faunas numerically dominated by them are documented in the Upper Triassic-Lower Jurassic-aged Gondwana formations exposed in the Pranhita-Godavari Valley of south-central and east-central India. The Upper Maleri Formation of the Pranhita-Godavari Basin preserves an early-middle Norian dinosaur assemblage numerically dominated by sauropodomorph dinosaurs, including at least two nominal species. However, the preliminary report of a herrerasaurian dinosaur specimen indicates that this assemblage of south-central Gondwana was more taxonomically diverse. Here, we describe and compare in detail the anatomy and assess the taxonomy and phylogenetic relationships of the Upper Maleri herrerasaurian specimen. A unique combination of character states present in this specimen allows the erection of the new genus and species Maleriraptor kuttyi. Updated quantitative phylogenetic analyses focused on early dinosauriforms recovered Maleriraptor kuttyi as a member of Herrerasauria outside of the South American clade Herrerasauridae. Maleriraptor kuttyi fills a temporal gap between the Carnian South American herrerasaurids and the younger middle Norian-Rhaetian herrerasaurs of North America. Maleriraptor kuttyi shows the first evidence that herrerasaurs survived also in Gondwana the early Norian tetrapod turnover that resulted in the global extinction of the rhynchosaurs.
