Gigantoscelus ("giant shin") is a dubious genus of basal sauropodomorph dinosaur from the Early Jurassic of South Africa.

Classification

It was first described by van Hoepen in 1916 on the basis of TrM 65, a distal femur from the Bushveld Sandstone Formation of South Africa.^[1] It was later synonymized with Euskelosaurus by van Heerden (1979),^[2] but was subsequently treated as a nomen dubium in the 2nd edition of the Dinosauria.^[3]

Stratigraphy

The type horizon of Gigantoscelus, the Bushveld Sandstone, was thought to be Late Triassic, but is now considered Early Jurassic (Hettangian-Sinemurian) in age.^[4]
