案例简介：照片由摩洛哥 @ paoloverzone Taouz提供。卡萨布兰卡哈桑二世大学古生物学教授Samir Zouhri拥有一颗大棘龙牙齿。棘龙是有史以来最大的掠食性恐龙之一。它以细长的背脊命名，支撑着巨大的皮肤 “帆”。与其他恐龙 (主要是陆生恐龙) 相比，一长串的解剖学特征表明，棘龙适合生活在淡水中，如鳄鱼和河马。关注我 @ paoloverzone以获得更多照片和故事。查看Nat Geo在bio中的链接以了解有关此故事的更多信息。

案例简介：Photo by @paoloverzone Taouz, Morocco. Samir Zouhri, professor of paleontology at Hassan II University of Casablanca, holds a large Spinosaurus tooth. Spinosaurus was one of the largest predatory dinosaurs of all time. It is named after the elongated dorsal spines that supported an enormous “sail” of skin. In contrast with other dinosaurs–predominantly terrestrial–a long list of anatomical features indicates that Spinosaurus was adapted to live in freshwater, like crocodiles and hippopotamuses.
