Spinostropheus is a genus of small ceratosaurian dinosaur that lived in the late Jurassic 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).
