Spinostropheus is a genus of small ceratosaurian dinosaur that lived in the early Cretaceous period of Niger. Once thought to be a species closely related to the abelisaurs (Sereno et al. 2002), subsequent studies have confirmed the original interpretation as a basal ceratosaur closely related to Elaphrosaurus (Carrano & Sampson, 2008).
Etymology
The name Spinostropheus is derived from the Greek spinos, meaning "spine" and strophe, meaning "vertebra", and refers to the epipophyseal processes of the cervical vertebrae, which are prominent and dorso-ventrally flattened.[1] The species, named decades before the genus as a species of Elaphrosaurus, refers to the discoverer of the type locality, F. Gautier.[1]
