 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.
