The genus Sharktooth currently includes two species, namely Sahara Sharktooth and Igidi Sharktooth. Shark toothed dinosaurs lived in North Africa during the late Cretaceous Cenomanian period. Shark toothed dragon has a very close genetic relationship with other members of the Allosaurus class, such as Kuizhoulong, Mapulong, and Southern Megalosaurus. The body size of the Shark toothed Dragon is extremely large, similar to that of the Tyrannosaurus Rex, and may even be larger. Shark toothed dinosaurs lived in an era of rampant giant beasts, including 15 meter long spiny dragons, 9-meter long wrinkled dragons, and over 30 meter long sauropod tidal dragons. There were also 12 meter long emperor crocodiles lurking in the water. Shark toothed dinosaurs are likely to have fed on giant sauropods of their time.
