Description: Hybodus is an extinct genus of shark that appeared at the end of the Permian, and disappeared at the beginning of the Late Cretaceous. During the Triassic, Jurassic, and Cretaceous periods, members of this genus were very successful.


The beds of Kem Kem are located along the border of Morocco with Algeria. These are continental deposits belonging to the Cretaceous period, specifically the Cenomanian stage (100.5 - 93.9 million years). The area is made up of a spectacular stone cliff that stretches 250 kilometers in length and comprises a mighty 150-200m sequence of fluvial siltstones and sandstones. Several species of vertebrates, including elasmobranchs, bony fishes, coelacanths, turtles, crocodiles, pterosaurs, dinosaurs, and birds have been found in this area. It is for this reason that various researchers from the most prestigious universities have referred to this site as "an area where the danger lurks by land, sea and air". They all agree that this site "constitutes a window to the Age of the Dinosaurs in Africa". It is precisely here, in Kem Kem, where the fossil remains of three of the largest predatory dinosaurs ever known.
