Geological and Paleontological Information

This fossil bivalve originates from marine deposits formed during the Lower Cretaceous, a time when Madagascar was part of the southern supercontinent Gondwana. These ancient seas supported a diverse array of molluscs, including bivalves like this example. While the exact genus and species are not specified, bivalves from this region and period are often linked to families such as Trigoniidae, Inoceramidae, or Ostreidae, common in Cretaceous marine strata.

6" FULLY ROOTED Genuine Spinosaurus Dinosaur Tooth Fossil, Kem Kem Beds, Cretaceous Morocco | Rare Authentic Specimen + COA

6" FULLY ROOTED Genuine Spinosaurus Dinosaur Tooth Fossil – Kem Kem Beds, Tegana Formation, Aptian Stage, Cretaceous: Kem Kem Basin, Morocco

An incredibly rare opportunity to own a fully rooted and beautifully preserved 6-inch fossil tooth from the infamous Spinosaurus aegyptiacus. This extraordinary fossil comes from the Kem Kem Beds within the Tegana Formation, part of the Kem Kem Basin, southeastern Morocco. It is from the Aptian stage of the Early Cretaceous, dating back approximately 113 to 100 million years ago.

Fossil Type & Species:

Type: Vertebrate Fossil (Tooth – Complete with Crown and Root)

Species: Spinosaurus aegyptiacus

Order: Theropoda

Superfamily: Megalosauroidea

Family: Spinosauridae

First Described By: Ernst Stromer, German palaeontologist, in 1915

Geological Details:

Formation: Tegana Formation

Beds: Kem Kem Beds

Geological Stage: Aptian (Early Cretaceous)

Age: ~113–100 million years ago

Biozone: Kem Kem Compound Assemblage Zone

Depositional Environment: Highly dynamic fluvial-deltaic system comprising seasonal rivers, floodplains, and shallow lakes. Ideal conditions for fossil preservation in iron-rich, fine-grained sediments.

Morphology & Features: This fossil tooth exhibits the classic features of Spinosaurid dentition with the rare inclusion of the root:

Complete structure with intact root and crown — exceptionally uncommon

Conical, slightly compressed form designed for grasping fish and aquatic prey

Vertical ridges along the enamel and a smooth surface lacking serrations

Earth-toned coloration from mineral-rich fossilisation (ochres, reds, browns)

Natural tip wear and preserved enamel integrity make this a scientific and visual standout

Notable: Fully rooted Spinosaurus teeth of this size are rarely found due to the fragility of the root during fossilisation and excavation. A complete specimen like this is highly valued by collectors and researchers alike.

Spinosaurus aegyptiacus is widely considered the largest known theropod dinosaur. Its crocodile-like snout, sail-backed posture, and aquatic lifestyle make it one of the most scientifically significant dinosaurs ever discovered.

Specimen Details:

Origin: Kem Kem Basin, near Taouz, Morocco

Formation: Tegana Formation, Kem Kem Beds

Species: Spinosaurus aegyptiacus

Fossil Type: Fully Rooted Tooth (Crown + Root)
