4.5″ Genuine Spinosaurus Dinosaur Tooth Fossil – Kem Kem Beds, Tegana Formation, Aptian Stage, Cretaceous: Kem Kem Basin, Morocco

This magnificent 4.5-inch fossilised tooth belonged to Spinosaurus aegyptiacus, one of the most unique and largest theropod dinosaurs ever discovered. Unearthed from the famous Kem Kem Beds within the Tegana Formation of the Kem Kem Basin in southeastern Morocco, this specimen originates from the Aptian stage of the Early Cretaceous, dating back approximately 113 to 100 million years.

Fossil Type & Species:

  • Type: Vertebrate Fossil (Tooth – crown specimen)
  • Species: Spinosaurus aegyptiacus
  • Order: Theropoda
  • Superfamily: Megalosauroidea
  • Family: Spinosauridae
  • Formally Identified By: German palaeontologist Ernst Stromer in 1915

Geological Details:

  • Formation: Tegana Formation
  • Beds: Kem Kem Beds
  • Geological Stage: Aptian (Early Cretaceous)
  • Biozone: Kem Kem Compound Assemblage Zone
  • Depositional Environment: Fluvial to deltaic ecosystem — characterized by ancient river channels, seasonal floodplains, and coastal lakes, ideal for preserving dinosaur remains in fine-grained sediments

Description

Genuine 4.5 Inch Spinosaurus Tooth – Authentic Dinosaur Fossil Specimen
This impressive 4.5-inch Spinosaurus tooth is a genuine fossil from one of the most iconic predators of the prehistoric world. Carefully selected for its size, preservation, and natural character, this specimen offers a striking example of theropod dentition from the Upper Cretaceous. The fossil shown in the photographs is the exact piece you will receive, ensuring complete confidence and individuality. It is accompanied by a fully hand-signed Premium Certificate of Authenticity, confirming its genuine origin and making it a highly desirable addition to any fossil collection.

Geological Provenance – Kem Kem Beds, Tegana Formation
This fossil originates from the Tegana Formation within the Kem Kem Basin of southeastern Morocco, a globally renowned fossil locality. 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 primarily of fluvial sandstones and siltstones, representing ancient river systems, floodplains, and deltaic environments. This region has produced an extraordinary diversity of vertebrate fossils, including 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 widely regarded as one of the largest carnivorous dinosaurs ever discovered. Unlike most theropods, it is believed to have been semi-aquatic, adapted to hunting within riverine and coastal environments. Its distinctive teeth are among the most recognisable features of the species and are commonly found within the Kem Kem Beds.

Morphology and Diagnostic Features
The tooth displays classic Spinosaurid characteristics, including 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 running along its length. The gentle curvature enhances its ability to capture and hold slippery prey such as fish. Subtle wear patterns may be visible, reflecting feeding activity during the animal’s lifetime. The enamel has been well preserved, with natural mineralisation producing rich earthy tones that enhance its visual appeal.

Depositional Environment and Fossilisation
During the Cenomanian stage, the Kem Kem region was a lush and dynamic ecosystem dominated by extensive river channels, floodplains, and wetlands. Spinosaurus occupied a top predator niche within this environment, feeding on both aquatic and terrestrial prey. Teeth were regularly shed throughout the animal’s life and became incorporated into sediment. Rapid burial protected these remains from erosion and scavenging. Over millions of years, mineral-rich groundwater replaced the original organic material, preserving the tooth in fossil form.

Condition, Size, and Display Value
At approximately 4.5 inches in length, this tooth is a substantial and visually striking specimen, ideal for display or as a centrepiece in any fossil collection. Its natural texture, colouration, and preservation highlight its geological history and authenticity. The size and overall condition make it highly desirable among collectors, educators, and enthusiasts of prehistoric life.

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 and presentation. All images accurately represent the exact fossil you will receive, providing complete confidence in your purchase and its provenance.

Cretaceous Information

The Cretaceous Period (145–66 million years ago) was the final era of the Mesozoic, marked by the dominance of dinosaurs and the rise of flowering plants. It had a warm, greenhouse climate, with high sea levels that created vast shallow inland seas. Marine life flourished, including mosasaurs, ammonites, and rudist reefs, while the land was ruled by iconic dinosaurs like Tyrannosaurus rex, Triceratops, and Spinosaurus. Mammals and birds diversified, and insects thrived. The period ended with the mass extinction event, likely caused by an asteroid impact, wiping out the dinosaurs and paving the way for the rise of mammals in the Cenozoic.
