Bidspirit auction | Fossilized jaw of a Mosasaur

Fossilized jaw of a Mosasaur - a giant marine predator from the Late Cretaceous period. - The item dates back 48-55 million years. Dimensions: 11x9 cm, thickness 16 mm, weight 110 g. Mosasaur teeth from Morocco with root and part of the jawbone, partially restored bone, still showing the 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 mosasaurs and also one of the largest. Like most mosasaurs, its limbs had evolved into short but efficient flippers, and the front flippers were larger than the hind flippers. The largest known species, M. hoffmannii, could reach lengths of 17-18 meters (56 feet), slightly longer than its closest relatives Tylosaurus and Hainosaurus. Moreover, Mosasaurus was also the most robust among the mosasaurs, reaching a remarkable weight of 25-30 tons in the most developed specimens, especially with a skull that 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.”
