Elephantosaurus is an extinct genus of dicynodont from the Middle Triassic (Ladinian) Bukobay Formation. The holotype and only known specimen, catalogued as PIN 525/25, is a fragment of the skull that includes portions of the left interorbital region and nasal bones, and suggests a very large animal with a skull at least 30 centimetres (12 in) wide[1] (although it may have been smaller than Stahleckeria). The bones of the skull roof are also unusually thick. While usually considered a member of the Stahleckeriidae, generally due to its size, it probably falls just outside the group due to its frontal bone contributing substantially to the margin of the eye socket.[2]
