Commonly known as the dawn runner, the Eocursor is a primitive genus of ornithischian dinosaurs that were found in the Early Jurassic Age which spanned from 201.3-174.1 million years ago. The epoch begins immediately after the Triassic-Jurassic extinction event. During that period, the dinosaur must have roamed several parts of the African continent.

The word Eocursor is a combination of two words, eos, and cursor. The word eos generally means the deity of dawn in Greek mythology while the word cursor means runner in Latin.

Fossils have been discovered from the Upper Elliot Formation, South Africa which suggests that the dinosaur was one of the early members of the Ornithischia order, the fossils also provide details about the early evolution.

The remains also interpreted that the dinosaur lived during the Late Triassic Period around 210 million years ago but this notion was rejected lately. In 1993, the discovery of the fossils took place but it took around 14 years to formally describe the dinosaur.

A group of paleontologists which consisted of Richard J. Buttler, David B. Norman, and Roger Smith described the type species, Eocursor parvus in 2008.

It was a small bipedal dinosaur while an average length was around 3 ft (1 m), the average weight is said to be around 44.09-55.11 lb (20-25 kg). The dinosaur highly resembled other Early Jurassic Ornithischia species such as Scutellosaurus and Lesothosaurus.

The large hands of the species were very much similar to those of Heterodontosauridae, a group of primitive ornithischians.

The structure of the triangular teeth suggests that the species must have been an omnivore. While talking about the leg bones, the legs were short while the shinbone was quite longer than the thighbone, suggesting the dinosaur was a swift runner.

Let's read more fun facts about the Eocursor, and if you find this article interesting, don't forget to check out exciting facts about different animals like Notoceratops and Marginocephalians.

Competition among dinosaurs can also be regarded as one of the major causes of extinction.

Where did Eocursor live?

In 1993, the remains were discovered in the Upper Elliot Formation, currently a part of the Free State Province of South Africa. The fossils were discovered by paleontologists of the Natural History Museum, the University of Cambridge, the Iziko South African Museum.
