Elaphrosaurus 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.
Jurassic Park Series
Elaphrosaurus never appears in the original novels or movies. However, a silhouette of Elaphrosaurus is shown on the Holoscape screen in the Innovation Center of Jurassic World, though it is currently unknown if any reside within the park itself.
It does appear, however, in Topps comics (the head of which is entirely speculative, as no skull has been preserved for this genus).
