植龙目![]() ![]() ![]() 植龙目(学名:Phytosauria)是群大型半水生掠食动物,身长2到12公尺,繁盛于晚三叠纪。植龙目属于主龙类,只有一科植龙科(Phytosauridae)或称副鳄科(Parasuchidae)。植龙目具有长口鼻部与厚重鳞甲,在体型、外表、以及生活方式等方面与现代鳄鱼类似,这是一个平行演化或趋同演化的例子。植龙目的名称 「Phytosauria」意为「植物蜥蜴」,容易被人误解为草食性动物,但牠们用来猛咬的颌部显示出牠们是掠食动物。但首次叙述植龙目的人,误以为他所研究的标本是草食性动物。 虽然植龙目并非真正的鳄鱼,牠们与鳄鱼有接近亲缘关系,因为植龙目与原始鳄鱼拥有共同的镶嵌踝类主龙祖先。但广为大众所知的鳄鱼首次出现在侏㑩纪早期,而植龙目已在数百万年前的三叠纪末灭亡了。

Phytosaur 植龙目![]() ![]() ![]() ![]() Phytosaurs are an extinct group of large semi-aquatic Late Triassic archosauriform reptiles. Phytosaurs belong to the family Phytosauridae and the order Phytosauria. Phytosauria and Phytosauridae are often considered to be equivalent groupings containing the same species, but some studies have identified non-phytosaurid phytosaurians. Phytosaurs were long-snouted and heavily armoured, bearing a remarkable resemblance to modern crocodilians in size, appearance, and lifestyle, as an example of convergence or parallel evolution. The name "phytosaur" means "plant reptile", as the first fossils of phytosaurs were mistakenly thought to belong to plant eaters. The name is misleading because the sharp teeth in phytosaur jaws clearly show that they were predators. |
