5.23" Serrated, Carcharodontosaurus Tooth - Huge Tooth!

This is a huge, 5.23" long Carcharodontosaurus tooth from the Kem Kem Beds of Morocco. It's rare that you get Carch teeth of this size in this nice of condition. Most of the large teeth you see on the market are heavily restored or composites.

The tooth has a wide, knife-like blade with visible serrations on both edges. The tooth has minor glue stabilization where it was fractured/crushed by geological forces while in the ground in addition to some natural fracturing. There is only minimal gap fill restoration through the repairs and at the proximal end near the partial root. The enamel is a bit spotty in some areas and a few of the serrations are missing, though this doesn't take away from the appeal of this phenomenal tooth. There may be some compositing along the distal edge of the crown, particularly near the tip.


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Past the Turonian (93.9-89.8 mya), Carcharodontosaurus might have been replaced by the smaller abelisaurids in Gondwana and by tyrannosaurids in North America and Asia.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 Group is 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.
