Physical properties
Hardness: 5 (Mohs), Color: Orange-brown with beige root, Luster: Vitreous to dull, Structure: Conical with slight curvature and fluting, Specific Gravity: ~3.0
Formation & geological history
Formed through permineralization where minerals replaced organic matter in marine environments. These fossils primarily date to the Late Cretaceous period (approx. 66-100 million years ago).
Uses & applications
Paleontological study, education, and highly popular as display specimens for fossil collectors.
Geological facts
Mosasaurs were apex marine predators, not dinosaurs. They could reach lengths of 50 feet and had an extra row of teeth on the roof of their mouths to hold onto slippery prey.
Field identification & locations
Identify by its conical, nonserrated shape and a distinct 'root' bulb at the base. Commonly found in the phosphate mines of Morocco (Oulad Abdoun Basin).
