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.

鸟鳄科——具有超特化下颌装置的早期主龙

摘要

早期的主龙包括一系列生态类型——从掠食动物到食草动物，从陆生到半水生。鸟鳄科的成员传统上被认为是活跃的掠食者，占据着特殊的地位。它们特征性的下颌器官结构和颅后骨骼的形态表明，祖龙类中形成了一种独特的生态类型，即中型超异齿巨食性捕食者。同时，在鸟鳄科、剑齿兽类和哺乳动物之间也可以发现一些类似物。
