The Afrovenator was discovered in Tiouraren Formation located in Nigar, Abaka, Africa. There has been only one almost complete skeleton fossil ever found. This includes most of the skull (except the mandible, or lower jaw), parts of the spinal column, hands, and forelimbs, a nearly complete pelvis, and complete hind limbs.

This carnivore moved on two hind legs with a lot of teeth and three claws on each hand. This dinosaur was about 9 meters long.

Originally the Afrovenator is in the Megalosauridae family. This is a family of theropods that are very hard to classify. In 2002 the dinosaur was defined into a different family called Sponosauridae although still it is formally classified in the Megalosauridae family.
