Classification: Chordata,‭ ‬Reptilia,‭ ‬Sauropterygia,‭ ‬Pistosauria,‭ ‬Plesiosauria.
Species: D.‭ ‬blanfordi‭ (‬type‭)‬.

Time period: Coniacian of the Cretaceous.
Fossil representation: Partial remains.

       When first named in‭ ‬1979,‭ ‬Dravidosaurus was described as a stegosaurid dinosaur,‭ ‬and given that the holotype was in a Coniacian of the late Cretaceous aged deposit,‭ ‬possibly the last stegosaur to exist.‭ ‬However,‭ ‬this claim seems to have been made prematurely,‭ ‬as in‭ ‬1991‭ ‬a palaeontologist named Sanker Chatterjee visited the site fossil site and identified the remains as being those of not a stegosaur,‭ ‬or even a dinosaur,‭ ‬but instead a partial pelvis and hind‭ ‬limb of a plesiosaur.‭ ‬Chatterjee followed this up in a‭ ‬1996‭ ‬paper co-authored with Rudra,‭ ‬and in‭ ‬2011‭ ‬another study,‭ ‬this time by Wilson,‭ ‬Barrett and Carrano confirmed that the holotype remains of Dravidosaurus are indeed from a plesiosaur.
