One of the earilest ornithomimids (ostrich dinosaurs), Elaphrosaurus was a relative of Dromiceiomimus, Gallimimus, Ornithomimus, and Struthiomimus. It was probably one of the the earliest members of that family and fossil bones have been found that date back to the late Jurassic period. Most "ostrich dinosaurs" are found from the Cretaceous period. A distant relative is Ornitholestes, a small dinosaur only half the size of Elaphrosaurus.

With long, slender legs and a stiff tail, Elaphrosaurus would have easily sprinted from danger. It had keen eyes and a quick brain. Its diet probably depended on where it lived. Near the sea it might have grubbed around for shellfish or shoveled sand for tiny creatures. Some lived far inland and others foraged among woods and forests. Since it had no teeth, Elaphrosaurus could not have eaten meat.
