Stunning Enormous Prognathodon Curii (Mosasaur) Rooted Tooth - Late Cretaceous Rare Mosasaur Species - Fossil tooth (No Reserve Price)

Scientific name: †Prognathodon currii, sp. nov. 2002 - Mosasaur tooth

Location: Oued Zem, Morocco

Geological Formation: Ouled Abdoun Basin (Phosphate beds)

Age: Upper Cretaceous, Maastrichtian stage, (~66 Million Years)

Size: 14,8cm long

Ref: S248

Observations: This enormous Prognathodon tooth is quite stunning, not only for its size and preservation, but also because it belongs to a rather rare Prognathodon species. Many mosasaur species have been described from the late Cretaceous Phosphate Beds of the Ouled Abdoun Basin, some more common than others. In this case, Prognathodon currii is quite unusual.

This tooth is fully rooted. However, during its excavation, the crown broke and separated from the root. Therefore, this specimen was subsequently restored by gluing and filling the tooth and reattaching the crown to the root. Apart from that, there is no more restorations on it.

Another very interesting aspect of this specimen is that a germ-emerging replacement tooth is visible within the root. Mosasaurs, like sharks or terrestrial dinosaurs, continuously replace their teeth throughout their lives. When a tooth begins to wear down, a new one starts to grow underneath and replaces it. Here is a magnificent example.

Very rare mosasaur in Morocco, most of the specimens belonging from the level 3 in Sidi-chenan locality more rare in Khouribga in upper level 3. Never founded a complete skull until now. There seem to be 1 more specie in Couche IV- in sidi chenane , a currii-like species with slender teeth.

Diagnose:

Teeth heavy with smooth enamel surfaces, tooth crowns nearly straight, conical with blunt apices, with bicarinate, occasionally serrated, carinae. 11 maxillary teeth, set on heavy, weakly striated pedicles. Dentary with nearly horizontal alveolar margin, 12 dentary teeth. Posterior horizontal inflection on mandibular retroarticular process.
