Afrovenator

Afrovenator was a theropod dinosaur from the Middle Jurassic of northern Africa. It was a bipedal meat-eating predator with long bladelike teeth. Fossils have been found in Abaka, Niger in the southern Sahara desert. A nearly complete "Afrovenator" was found in 1993. It is one of the most complete dinosaurs found in Africa so far. 
The rocks where it was found were redescribed as "mid-Jurassic" after the discovery had been announced.
It is in a group of theropods which are known as the Megalosaurs.
