Tympanocryptis pinguicolla, also known as Victorian grassland earless dragon, is a critically endangered species of lizard in the family Agamidae.

[4] The animal seeks cover in small holes or beneath rocks, and the diet consists of invertebrates.

Intensive land use and conversion of the basalt grasslands surrounding the highly populated city of Melbourne were seen as the main contributors to the species' decline.

Though later searches found nothing,[3] not all of the remaining grasslands in the area were intensively surveyed and the species is small and hard to detect.

[8][7] Colossal Biosciences and Zoos Victoria began a conservation project in October 2023 to preserve the species as well as sequence its genome.
