A good fossil crocodile tooth 21mm discovered in the Late Cretaceous Kem Kem Beds of North Africa. It is challenging to determine specific species based on a single tooth. Prehistoric crocodile dentition is varied making identification almost impossible in some cases. Four crocodilian species have been identified to have been present during the Cretaceous: Elosuchus cherifiensis, a Trematochampsid, Araripesuchus rattoides and Laganosuchus maghrebensis.
Condition report; Superb glossy enamel of dark mahogany colour is the redeeming factor of this unique fossil tooth until upon close inspection one finds it is completely unbroken. The crown complete with carina cutting edges. the tip is complete with life wear and enamel loss at the apex, affirming use in the jaw of the predator. An excellent representative fossil croc tooth from the location.
The Kem Kem Beds (also referred to by various names including the Continental Red Beds and Continental intercalaire) is a geological formation along the border between Morocco and Algeria in southeastern Morocco, whose strata date back to the Late Cretaceous. Crocodylomorpha is a group of archosaurs that includes the crocodilians and their extinct relatives. During Mesozoic and early Cenozoic times, crocodylomorphs were far more diverse than they are now. Triassic animals were smaller, lightly built very active terrestrial animals. Modern crocodilians do not appear in the fossil record until the Late Cretaceous.
Vertebrate fossils including the dinosaurs and crocodilians are found in three of the formations of the Kem Kem Beds. The Aoufous Formation is a geological deposit that contains some of the vertebrate assemblages of the Kem Kem Beds, of Late Cretaceous date. Two other formations comprise the Kem Kem beds: the Ifezouane Formation (below the Aoufous Formation) and the Akrabou Formation (above the Aoufous). The Aoufous Formation of Morocco produces similar fauna to that found in the Bahariya Formation of Egypt. In both formations, Carcharodontosaurus saharicus and Spinosaurus aegyptiacus are to be found. As are species of crocodilians and fishes.
The two formations appear to be closely associated by the fauna; this leads to extrapolate a theory that the whole North African region was a tidal floodplain, rich in all forms of Cretaceous aquatic and semi-aquatic animals including the predator crocodiles.
