Plateosauravus cullingworthi

Plateosauravus ("grandfather of Plateosaurus") is a basal sauropodomorph of uncertain affinities from the Late Triassic Elliot Formation of South Africa.

Sidney Haughton named Plateosaurus cullingworthi in 1924 from a partial skeleton,[1] type specimen SAM 3341, 3345, 3347, 3350-51, 3603, 3607. The specific name honoured collector T.L. Cullingworth. Friedrich von Huene reassessed it in 1932 as belonging to a new genus, which he named Plateosauravus.[2] Jacques van Heerden reassigned it to Euskelosaurus in 1976, and this has been how it was usually considered.[3] However, recent study indicates that Euskelosaurus is based on undiagnostic material and thus a nomen dubium; in his series of sauropodomorph and basal sauropod papers, Adam Yates has recommended no longer using Euskelosaurus and has suggested the use of Plateosauravus instead.[4][5][6]

More than a dozen additional partial skeletons have been found in the Kruger National Park after a discovery by game warden Adriaan Louw on 27 March 1995. These include juvenile individuals.[7]
