Description

This exceptional fossil tooth comes from a specimen of Spinosaurus aegyptiacus, one of the most enigmatic and studied theropod dinosaur species of the Cretaceous. Its dentition, unique among large Mesozoic predators, was perfectly adapted to a piscivorous diet, as demonstrated by the smooth, conical tooth morphology, lacking serrations and featuring a sharp, curved apex. These characteristics indicate a hunting strategy based on gripping and holding slippery prey such as fish and aquatic reptiles.
The tooth stands out for its excellent state of preservation, with a portion of the root still present. The well-visible vertical striations are growth structures that provide valuable information about the animal's development and age at the time of tooth replacement.

Species: Spinosaurus aegyptiacus
Family: Spinosauridae
Period: Late Cretaceous, about 95 million years ago (Cenomanian)
Location: Kem Kem Formation, Morocco
Environment: Tropical river and deltaic systems

Spinosaurus is known to have evolved extraordinary characteristics: very tall dorsal vertebrae supporting a "sail", relatively short hind limbs and strong forelimbs with large claws, indicating adaptation to an amphibious lifestyle. Recent paleontological discoveries have even hypothesized the presence of a laterally flattened tail, used as a propeller in water, a unique trait among theropods.
This tooth is therefore concrete evidence of the evolution of a highly specialized predator capable of dominating a complex river ecosystem. A collectible item of great scientific and paleontological value.
