来自摩洛哥的美丽莫萨斯龙颚骨，带有牙根和部分下颌骨。该骨骼已部分修复，但化石的天然多孔性仍然清晰可见。它是在 Khouribga 的磷矿沉积物中发现的。这只白垩纪海洋爬行动物当时是最大的海洋捕食者之一。 
Mosasaurus 是最末期的莫萨斯龙之一，也是体型最大的之一。像大多数莫萨斯龙一样，其四肢进化为短而高效的鳍肢，前鳍大于后鳍。已知最大的物种 Mosasaurus hoffmannii 可达到 17–18 米（56 英尺）长，略长于近亲如 Tylosaurus 与 Hainosaurus。它也是最健壮的莫萨斯龙之一，部分个体估计体重介于 25 到 30 吨之间。身体长而厚实，呈桶状，头骨庞大，颚部强大且紧密连接。眼睛相对较大，但很可能提供的立体视野有限，嗅球发育也不充分，因此专家们认为 Mosasaurus 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.
