Knoll 2010

Ignavusaurus is an extinct monospecific genus of basal sauropodomorph dinosaur that lived during the Early Jurassic in what is now Lesotho. Its fossils were found in the Upper Elliot Formation which is probably Hettangian in age around 200 million years ago. It was described on the basis of a partial, well preserved articulated skeleton. The type species, Ignavusaurus rachelis, was described in 2010 by Spanish palaeontologist F. Knoll.
