About Spinostropheus
What it was like
Spinostropheus was a lightly built, two-legged predator known from parts of the backbone and limbs. It was first thought to be a species of Elaphrosaurus. Later studies placed it among the early ceratosaurs.

It lived in the Jurassic in what is now Niger. Its bones come from the Tiourarén Formation, a land of rivers shared with the long-necked Jobaria and the predator Afrovenator.
How it was found
Sereno and colleagues gave it its own genus in 2004.
