Aardonyx (Afrikaans aard, “earth” + Greek , “nail, claw”) is a genus of basal sauropodomorph dinosaur. It is known from the type species Aardonyx celestae found from the Early Jurassic Elliot Formation of South Africa. A. celestae was named after Celeste Yates, who prepared much of the first known fossil material of the species. It has arm features that are intermediate between basal sauropodomorphs and more derived sauropods.
Based on the structure of the hind limbs and pelvic girdle of Aardonyx, the dinosaur normally moved bipedally but could drop to quadrupedal movement similar to Iguanodon. It shares some attributes with giant quadrupedal sauropods like Apatosaurus. Australian paleontologist Adam Yates and his team’s discovery of the genus was published online before print in Proceedings of the Royal Society B in November 2009, and was scheduled to appear in the March 2010 issue.
