化石拍卖（史前巨人）

来自摩洛哥的美丽摩斯角龙颚骨，牙齿带着牙根，包含下颌骨的一部分。骨骼已部分修复，但化石的自然多孔性仍清晰可见。它是在 Khouribga 磷酸盐矿床中发现的。这种白垩纪海生爬行动物是当时最大的海洋掠食者之一。

Mosasaurus 是晚期摩萨龙中的代表之一，也是体型最大的之一。像大多数摩萨龙一样，它的四肢进化为短而高效的鳍肢，前鳍比后鳍更大。已知的最大物种 Mosasaurus hoffmannii 的长度可达 17–18 米（56 英尺），略长于近缘种如 Tylosaurus 和 Hainosaurus。它也是最健壮的摩萨龙之一，一些个体的体重估计在 25 到 30 吨之间。它的身体修长、粗壮、呈桶状，头部巨大，颚部强大且紧密相连。眼睛相对较大，但很可能提供的双眼视觉有限，嗅球发育也不充分，专家因此认为 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.
