Eocursor (meaning "dawn runner") was a primitive genus of dinosaur which lived during the Late Triassic (Norian age), around 210 million years ago. It was an ornithischian which lived in what is now South Africa. Remains of this animal have been found in the Lower Elliot Formation and are the most complete known from a Triassic ornithischian, shedding new light on the origin of this group.
