Physical properties
Mohs hardness: 5 (Enamel); Color: Brown to tan; Luster: Dull to sub-vitreous; Structure: Conical, non-serrated, straight or slightly curved
Formation & geological history
Formed via permineralization during the Cretaceous period (approx. 95-112 million years ago) specifically within the Kem Kem Group river systems of North Africa.
Uses & applications
Paleontological study, educational exhibits, and private specimen collecting.
Geological facts
Spinosaurus was one of the largest carnivorous dinosaurs, longer than T-Rex. Its teeth were conical specifically for gripping slippery aquatic prey like giant fish.
Field identification & locations
Identified by the absence of serrations and a vertical fluting texture. Commonly found in the Kem Kem Basin of Morocco. Field identification involves looking for the 'striations' along the length of the tooth.
