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.
期刊介绍：
Paleontological Journal (Paleontologicheskii zhurnal) is the principal Russian periodical in paleontology. The journal publishes original work on the anatomy, morphology, and taxonomy of fossil organisms, as well as their distribution, ecology, and origin. It also publishes studies on the evolution of organisms, ecosystems, and the biosphere and provides invaluable information on global biostratigraphy with an emphasis on Eastern Europe and Asia.
