Mosasaur - Fossil mandible bone - Globidens SP

Globidens sp. jaw — Durophagous mosasaur of the Cretaceous

Sidi Chennane phosphate mines, Oulad Abdoun Basin, Morocco

Exceptional pair of fossil mandible ramus belonging to Globidens, one of the most distinctive mosasaurs of the Late Cretaceous (Maastrichtian, ~66-70 million years). Unlike other mosasaurs with sharp teeth, Globidens developed a highly specialized globular and hemispherical dentition to crush mollusks, ammonites and other hard-shelled invertebrates — a relatively uncommon durophagous adaptation among marine reptiles.

Features of the specimen:
• Length of each mandibular ramus: 33 cm

• Dentary series practically complete, with teeth in different stages of eruption and replacement, showing the natural growth pattern of the animal
• Rounded and bulbous crowns perfectly preserved, with original enamel visible
• Natural phosphate mineralization, with the typical cream-ivory color of bone and brown tones in the dental enamel
• Authentic piece, with no restoration or reconstruction added
