07780 - Top Huge 4.89 Inch Mosasaur (Prognathodon anceps) Tooth in Jaw Bone Cretaceous Cyphaspis ("Devil Horned") Acanthopyge is an extinct genusThis enormous Prognathodon tooth is preserved in exceptional way, inside his own jaw bone. This partial jaw was broken in small sector near the tip of the tooth tip during the initial collecting efforts but all parts were put back together and there is no restoration and no fabrication. The size corresponds without doubt to an adult individual. The tip of the tooth is perfectly preserved and tremendously pointed. The quality of the enamel is very high
