Rebbanasaurus is an extinct sphenodontian reptile known from remains found in the Early-Middle Jurassic Kota Formation of India.[1] The type specimen is a partial jawbone which has acrodont teeth, with other known remains including fragments of the premaxilla, maxilla, and palatine. It was relatively small, with a skull estimated at 1.5–2.5 centimetres (0.59–0.98 in) long.[1] It is generally considered to be a relatively basal sphenodontian that lies outside Eusphenodontia.[2]
