Mosasaur - Fossil tooth - 13 cm (No reserve price)

Mosasaurus teeth from Morocco with root and part of the mandibular bone, partially restored bone, still showing natural bone porosity. Discovery in the northwestern Sahara area. This Cretaceous animal was one of the largest marine predators.
Mosasaurus was one of the last mosasaurids, as well as one of the largest. Like most mosasaurids, its limbs had evolved into short but efficient fins, with the front fins being larger than the rear fins. The largest known species, M. hoffmannii, could reach a length of 17-18 meters (56 feet), slightly longer than its closest relatives Tylosaurus and Hainosaurus. Additionally, Mosasaurus was also the most robust among mosasaurids, reaching an impressive weight of 25-30 tons in the most developed specimens, especially the skull, which had a jaw closely connected to the skull. The body was long, thick, and barrel-shaped. The eyes were relatively large but provided poor binocular vision, and the olfactory bulbs were underdeveloped; therefore, experts believe that Mosasaurus lived near the surface.
