DESCRIPTION:
Afrovenator ("African hunter") is a genus of megalosaurid theropod dinosaur from the Middle Jurassic Period of northern Africa. The remains of Afrovenator were discovered in 1993 in the Tiourarén Formation of the department of Agadez in Niger.
The Tiourarén Formation is a geological formation in the Agadez Region of Niger whose strata were originally thought to be Early Cretaceous. However, re-interpretation of the sediments showed that they are probably Middle Jurassic (Bathonian) in age. It is the uppermost unit of the Irhazer Group. Dinosaur remains are among the fossils that have been recovered from the formation.
