Dravidosaurus

drah-VID-oh-SORE-us /drɑˌvɪdoʊˈsɔːrəs/

Nomen dubium

Dravida lizard

  • Dravida · Sanskrit/Latin · relating to the Dravidian people / southern India
  • saurus · Greek · lizard

The name combines "Dravida," a Sanskrit term referring to the Dravidian-speaking peoples and lands of southern India, with the Greek word "sauros" meaning lizard. It was named in reference to the region of India where the fossils were discovered — the Trichinopoly (Tiruchirappalli) district of Tamil Nadu, a heartland of Dravidian culture. The name thus means "Dravida lizard" or "lizard from Dravidian India."

Originally described as a stegosaur — which would make it the last-known stegosaur and the only one from the Late Cretaceous — but subsequent studies have cast serious doubt on this identification. The fragmentary material (partial skull, some postcranial elements) has been reinterpreted by several researchers as belonging to a plesiosaur, not a dinosaur at all. It is now widely regarded as a nomen dubium, and the stegosaur assignment is considered almost certainly erroneous. If the plesiosaur reinterpretation is correct, it is not a dinosaur.
