Elaphrosaurus (meaning "lightweight lizard") is a genus of theropod dinosaur from the Kimmeridgian stage of the Late Jurassic of Tanzania. Elaphrosaurus was probably a ceratosaur about 6 meters (20 ft) long. Suggestions that it is a late surviving coelophysoid have been entertained but are generally dismissed. It was first described as a coelurid. At the time, Coeluridae was a wastebasket taxon for small theropods. Later, it was thought that Elaphrosaurus was related to ornithomimids, but this has also lost favor in preference to a ceratosaurian identity.
