Spinosaurus

Authentic Fossil Teeth from a Legendary Predator

Explore genuine fossil teeth from one of the most unusual predatory dinosaurs ever discovered. These striking specimens show rich natural colors, glossy enamel, and impressive preservation. Many pieces remain complete, with only minimal stabilization to ensure long-term durability. Fossil hunters recover these teeth from the Sahara Desert in North Africa, where ancient river systems once supported diverse wildlife. Each tooth represents a real piece of deep time and makes a standout addition to any serious fossil collection.

Collectors value these fossils for their elongated, conical shape and smooth enamel texture — features that helped this animal grip slippery prey. Their condition and visual appeal make them ideal for collectors, educators, and natural history enthusiasts who want authentic prehistoric material.

About the Animal Behind the Teeth

This massive North African theropod ranks among the largest meat-eating dinosaurs scientists have identified. Researchers estimate it reached lengths of 41–59 feet (12.5–18 meters) and weighed well over 7 tons. Unlike most other large predatory dinosaurs, it shows clear adaptations for a semi-aquatic lifestyle and likely spent much of its time in rivers and coastal environments.

Its long, narrow snout resembled a crocodile’s and held straight, conical teeth that gripped fish and other aquatic prey. Bone structure and fossil evidence indicate dense bones that improved buoyancy control, and recent studies suggest the tail helped power it through the water.

The Famous Sail-Backed Giant

Tall neural spines formed the distinctive sail along its back and gave this dinosaur its dramatic profile. Scientists still debate the sail’s exact role, but many propose display, temperature control, or energy storage as possible functions.

This predator lived roughly 112 to 97 million years ago during the Cretaceous Period in what is now North Africa. Fossils from this region continue to help researchers understand how large predators adapted to river and coastal ecosystems.
