Serrated, 3.35" Fossil Carcharodontosaurus Tooth - Morocco

This is a serrated 3.35" long Carcharodontosaurus tooth from the from the Kem Kem Basin, Morocco. This tooth has good enamel with areas of serration missing. Other serrations are worn but visible. There are a couple of repairs with thin gap fills in the repaired cracks.

Carcharodontosaurus was a massive theropod often compared to T-Rex. It is now thought to have been larger.


Carcharodontosaurus comprised a genus of dinosaurs that dominated the land between 100-93 million years ago, during the mid-Cretaceous Period. This genus is currently known to include two gigantic species, which were among the largest known predatory dinosaurs. There were immense as the genera Tyrannosaurus and Giganotosaurus, but not as colossal as Spinosaurus.

Along with the spinosaurids, carcharodontosaurids were the largest predators in the early and middle Cretaceous throughout Gondwana, with species also present in North America (Acrocanthosaurus), and Asia (Shaochilong). Various scientists submit length estimates for C. saharicus ranging between 12 and 13 m (39-43.5 ft) and weight estimates between 6 and 15 metric tons.





Carcharodontosaurids were a scourge of the land as giant, shark-toothed terrors in a world of monsters. Though spinosaurids would have been a formidable enemy, they may have occupied a semi-aquatic niche which reduced competition. Both giant hunters also shared their world with menacing, 30 foot ancient crocodiles that had a taste for dinosaur.

Past the Turonian (93.9-89.8 mya), Carcharodontosaurus might have been replaced by the smaller abelisaurids in Gondwana and by tyrannosaurids in North America and Asia. The disappearance of carcharodontosaurids, spinosaurids and other fauna in Gondwana and across the world, suggests a global replacement event. Despite the event, fossils discovered in Brazil which appear to be carcharodontosaurids, indicate some survivors of this group until the latest stage of the Cretaceous.

The Kem Kem Beds are famous for yielding a diverse, Late Cretaceous, vertebrate assemblage including fish, reptiles and dinosaurs such as Spinosaurus. These fossils are found in a thin bed that outcrops around the edge of a large plateau near Taouz, Morocco. Local miners collect these fossils by digging narrow tunnels by hand into this plateau following the layer.
