Description
Rare Fully Rooted Spinosaurus Tooth – Genuine Dinosaur Fossil
This exceptional 4-inch Spinosaurus tooth is a rare, fully rooted fossil specimen from one of the most iconic predatory dinosaurs of the Cretaceous period. Carefully selected for its completeness, preservation, and visual appeal, this tooth stands out as a highly desirable collector’s piece. Fully rooted examples are significantly less common than isolated crowns, making this specimen particularly valuable. The fossil shown in the photographs is the exact piece you will receive, ensuring authenticity and uniqueness. It is accompanied by a fully hand-signed Premium Certificate of Authenticity, confirming its genuine origin and provenance.
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 productive dinosaur fossil 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 are composed of fluvial sandstones and siltstones formed in ancient river channels, floodplains, and deltaic systems. These environments supported a rich ecosystem of large theropods, crocodyliforms, fish, and other aquatic and terrestrial life.
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 considered one of the largest carnivorous dinosaurs ever discovered. Unlike most theropods, it is believed to have been semi-aquatic, adapted for hunting in riverine environments. Its distinctive conical teeth are among the most recognisable features of the species and are frequently found within the Kem Kem Beds.
Morphology and Diagnostic Features
The tooth displays classic Spinosaurid characteristics, including an elongated, conical crown with a smooth enamel surface and fine longitudinal fluting. Unlike many carnivorous dinosaur teeth, it lacks serrations, reflecting its specialised function for gripping rather than slicing prey. The gentle curvature of the crown enhances its effectiveness for catching slippery prey such as fish. The fully preserved root is a standout feature, providing insight into how the tooth was anchored within the jaw and significantly increasing both its rarity and scientific value. Natural mineralisation has preserved the tooth in rich, earthy tones, highlighting its authenticity.
Depositional Environment and Fossilisation
During the Cenomanian stage, the Kem Kem region was a lush and water-dominated landscape with extensive river systems and floodplains. Spinosaurus thrived in this environment, occupying a top predator role and feeding on both aquatic and terrestrial prey. Teeth were naturally shed throughout the animal’s life or lost during feeding. Once buried in sediment, rapid deposition protected them from erosion and scavenging. Over millions of years, mineral-rich groundwater replaced the original organic material, resulting in the fossil preserved today.
Condition, Size, and Display Appeal
At approximately 4 inches in length, this fully rooted tooth is an impressive and visually striking specimen. Its completeness, including the intact root, makes it highly desirable among collectors and enthusiasts. The natural texture, colouration, and preservation create a powerful display piece that captures the essence of prehistoric life. It is ideal as a centrepiece in any fossil collection or as an educational specimen.
Authenticity and Certification
This fossil is 100% genuine and includes a fully hand-signed Premium Certificate of Authenticity. The specimen has been carefully curated to ensure quality, authenticity, and presentation. All photographs accurately represent the exact fossil you will receive, providing complete confidence in your purchase and its provenance.
