Geological Provenance – Kem Kem Beds, Tegana Formation
This fossil originates from the Tegana Formation within the Kem Kem Basin of southeastern Morocco, one of the most famous fossil-bearing regions in the world. These deposits date to the Upper Cretaceous period, specifically the Cenomanian stage, approximately 95 to 100 million years ago. The Kem Kem Beds consist primarily of fluvial sandstones and siltstones, formed within ancient river systems, floodplains, and deltaic environments. This dynamic landscape supported a rich diversity of life, including large theropod dinosaurs, crocodyliforms, and aquatic fauna.

Species Identification – Spinosaurus aegyptiacus
This tooth is attributed to Spinosaurus aegyptiacus, a member of the family Spinosauridae within the order Theropoda. First described by Ernst Stromer in 1915, Spinosaurus is widely regarded as one of the largest carnivorous dinosaurs ever discovered. Unlike most theropods, it exhibited semi-aquatic adaptations, allowing it to thrive in water-rich environments. Its distinctive conical teeth are among its most recognisable features and are frequently recovered from the Kem Kem Beds.

Morphology and Diagnostic Features
The tooth displays classic Spinosaurid morphology, with a long, conical crown designed for gripping prey. Unlike many carnivorous dinosaur teeth, it lacks serrations and instead features a smooth enamel surface with fine longitudinal fluting. The gentle curvature enhances its ability to secure slippery prey such as fish. The fully preserved root is a key highlight, providing insight into how the tooth was anchored within the jaw and greatly increasing both its rarity and scientific value. The enamel surface shows natural wear and mineralisation, resulting in rich earthy tones that enhance its aesthetic appeal.

Depositional Environment and Fossilisation
During the Cenomanian stage, the Kem Kem region was a lush and water-dominated ecosystem with extensive river channels and floodplains. Spinosaurus occupied a top predator niche within this environment, feeding on both aquatic and terrestrial prey. Teeth were naturally shed throughout the dinosaur’s life or lost during feeding. Once deposited in sediment, rapid burial protected them from erosion and decay. Over millions of years, mineral-rich groundwater replaced the original organic material, preserving the fossil in remarkable detail.

Condition, Size, and Display Value
At approximately 5.5 inches in length, this tooth is a large and visually striking specimen, ideal as a centrepiece in any fossil collection. The combination of size, intact root, and well-preserved enamel makes it highly desirable. Natural textures and colour variations reflect its geological history, enhancing both authenticity and display appeal. This specimen offers a tangible connection to one of the most fascinating predators of the prehistoric world.
