化石拍賣（海洋生物）

来自摩洛哥的美丽莫拉萨龙颚骨，牙齿带根，并含有下颌骨的一部分。该骨骼已被部分修复，但化石的天然多孔性仍然清晰可见。它是在哈里布加的磷酸盐矿床中发现的。这种白垩纪海生爬行动物曾是当时最大的海洋掠食者之一。
莫拉萨龙（Mosasaurus）是最后一批摩拉萨龙之一，也是其中最庞大的之一。与大多数摩拉萨龙一样，它的四肢演化成短而高效的鳍肢，前鳍比后鳍大。已知最大种群，Mosasaurus hoffmannii，体长可达17–18米（56英尺），略长于近缘种如提洛萨龙（Tylosaurus）和海诺萨龙（Hainosaurus）。它也是最强健的摩拉萨龙之一，一些最大个体估计体重在25到30吨之间。它的身体修长、筒状，头骨庞大，颚部强健且紧密相连。眼睛相对较大，但可能提供的立体视野有限，嗅球发育不充分，专家因此认为莫拉萨龙主要生活在水面附近。

Beautiful Mosasaur jaw from Morocco, featuring teeth with roots and part of the mandibular bone. The bone has been partially restored, but the natural porosity of the fossil is still clearly visible. It was discovered in the phosphate deposits of Khouribga. This Cretaceous marine reptile was one of the largest ocean predators of its time.
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.
