Basutodon was a genus of suchian archosaur from the late Carnian-early Norian-age Upper Triassic Lower Elliot Formation of Lesotho.[1] The type species is B. ferox.

Discovery and naming

edit

The holotype is a single tooth that was discovered alongside the remains of Euskelosaurus browni in the Lower Elliot Formation, Lesotho. The species Basutodon ferox was named and described by von Huene (1932).[1]

"Likhoelesaurus ingens", an undescribed archosauriform from the Lower Elliot Formation of South Africa,[2] may have been the same animal as Basutodon ferox.[3][4]

Description

edit

Basutodon was once classified as a prosauropod, as with Teratosaurus. Because of this, it is sometimes listed in older dinosaur books as an early theropod,[5] or as a synonym of Euskelosaurus. It was probably neither of these things, though, and is much more likely to be a dubious non-dinosaur.[6]

Basutodon is currently listed as a basal member of Suchia,[3] although Tolchard et al. (2019) suggested that Basutodon may belong to Rauisuchia.[7]
