Abstract

Early archosaurs included a range of ecological types—from predators to herbivores and from terrestrial to semi-aquatic forms. Members of the family Ornithosuchidae, traditionally considered active predators, occupy a special position. Their characteristic jaw apparatus structure and the morphology of their postcranial skeleton suggest the development of a unique ecological type among archosaurs, namely, a medium-sized hyperanisodont macrophagous predator. At the same time, some analogs can be noted between ornithosuchids, saber-toothed therapsids, and mammals.

鸟喙龙--具有超特化下颌装置的早期古龙

摘要早期的古龙包括一系列生态类型--从食肉动物到食草动物，从陆生形式到半水生形式。鸟喙龙科（Ornithosuchidae）的成员历来被认为是活跃的食肉动物，它们占据着特殊的地位。它们特有的颌器结构和颅后骨骼的形态表明，它们是一种独特的生态型古龙，即一种中型的超猿齿巨型食肉动物。同时，在鸟龙类、剑齿龙类和哺乳动物之间也可以发现一些相似之处。
