Chroniosuchidae
Chroniosuchidae is a family of semi-aquatic tetrapods found in sediments from the upper Permian and the upper Triassic periods, most in Russia. They were generally rather large animals, with long jaws similar to those found in modern crocodiles, and probably lived a similar lifestyle as riverside piscivores and ambush predators. Like all chroniosuchians, they bore extensive osteoderm armour on their backs, possibly as protection against terrestrial predators such as the Permian therapsids and the Triassic rauisuchians.
Chroniosuchia
Chroniosuchia is a group of tetrapods that lived from the Middle Permian to Late Triassic in northern Pangaea in what is now Eurasia, including Laos, Kyrgyzstan, China, Germany and Russia. Chroniosuchians are often thought to be reptiliomorphs, but some recent phylogenetic analyses suggest instead that they are stem-tetrapods. They were all rather short limbed with a strong tail and elongated snout, somewhat resembling modern crocodiles. The group is traditionally considered to be a suborder or order of labyrinthodonts. Chroniosuchians likely had ecological niches as riverside predators, and m
