Physical properties

Hardness: 5 (Mohs scale); Color: Dark brown to reddish-tan due to iron mineralization; Luster: Sub-vitreous to dull; Structure: Conical, non-serrated, with fine longitudinal fluting.

Formation & geological history

Formed in fluvial (river) systems during the Late Cretaceous period (approx. 95-100 million years ago), specifically within the Kem Kem Beds of Morocco.

Uses & applications

Commercial fossil trade, education, paleontology research, and high-end private collections.

Geological facts

Spinosaurus was the largest known carnivorous dinosaur, even bigger than T-Rex. Unlike most theropods, its teeth were smooth and conical, specialized for catching slippery fish and aquatic prey.

Field identification & locations

Identify in the field by its distinct tapered cone shape and lack of serrations (serrations are common in T-Rex or Carcharodontosaurus teeth). Found primarily in North Africa, specifically Morocco and Egypt.
