Description

Imposing, with a broad base and well-mineralized apical surface, this fossil tooth of Spinosaurus aegyptiacus embodies the power and evolutionary uniqueness of one of the most controversial dinosaurs in modern paleontology. The visibly more massive section suggests a posterior mandibular position, functional for gripping and holding large prey. The arrangement of Spinosaurus teeth in rosettes, combined with the total absence of serrations, indicates a diet specialized in aquatic animals, though not exclusively so. The species in fact shows ambivalent adaptations: proven swimming abilities but also potential terrestrial mobility, fueling debate about its actual lifestyle. This specimen, with deep radial striations, offers a fascinating window into a Cretaceous predator whose traits challenge traditional classifications.

Origin: Kem Kem Formation (Moroccan Sahara)
Period: Late Cretaceous, about 95 million years ago (Cenomanian)
