Eocursor or “dawn runner” was a primitive genus of dinosaur which lived during the Late Triassic Period (210 mya). It lived in what is now South Africa. Its remains have been discovered in the Lower Elliot Formation and are the most complete known fossils of Triassic ornithischian. Though collected in 1993, the remains were not formally described until 2007 by Richard J. Butler, Roger M. H. Smith, and David B. Norman. The type species described was E. parvus.
Eocursor was a light bipedal dinosaur with a body length of nearly 3 feet. It had relatively large hands for its body size. It is thought that Eocursor was partially herbivorous due to its triangular teeth. The tibia was much longer than the femur, indicating Eocursor was a swift runner.
