滄龍 - 牙齒化石 - Mosasaur jaw from Morocco (沒有保留價)

来自摩洛哥的美丽 Mosasaurus 颚骨，牙齿带有根部，部分颌骨也可见。该骨骼已被部分修复，但化石原有的多孔性仍清晰可见。它在 Khouribga 的磷酸盐矿床中被发现。这种白垩纪海生爬行动物是当时海洋中最大的掠食者之一。
Mosasaurus was among the last mosasaurs and also one of the largest. Like most mosasaurs, its limbs had evolved into short but efficient flippers, with the front flippers larger than the rear ones. The largest known species, Mosasaurus hoffmannii, could reach lengths of 17–18 meters (56 feet), slightly longer than close relatives such as Tylosaurus and Hainosaurus. It was also one of the most robust mosasaurs, with some of the largest individuals estimated to weigh between 25 and 30 tons. Its body was long, thick, and barrel-shaped, with a massive skull and a powerful, tightly connected jaw. The eyes were relatively large but likely provided limited binocular vision, and the olfactory bulbs were not well developed, leading experts to believe that Mosasaurus lived primarily near the water’s surface.
