Konkasaurus (lit. 'very old lizard') is an extinct genus of plated lizard (family Gerrhosauridae), known from the Late Cretaceous (Maastrichtian age) Maevarano Formation of Madagascar. The genus contains a single species, Konkasaurus mahalana, known from a partial skeleton and several osteoderms. Konkasaurus was named and first described in 2003, at which point it was tentatively identified as a member of the family Cordylidae (girdled lizards). A more detailed analysis in 2026 using micro-CT scans of the available fossils instead suggested affinities with the cordylid sister group, Gerrhosauridae. Konkasaurus was the first lizard fossil identified from the Late Cretaceous of Africa, and is the oldest known lizard taxon from Madagascar.
