The Chroniosuchia are a suborder or order of labyrinthodonts that lived in the middle Permian and the upper Triassic periods of Eastern Europe, Kyrgyzstan,^[1] China and Germany.^[2] They were all rather short limbed with a strong tail and elongated snout, somewhat resembling modern crocodiles. They likely had ecological niches as riverside predators, and may have been competed out with the advent of real crocodiles in the late Triassic. Most forms bore a heavy armour of scutes along the back, possibly for protection against land born predators like therapsids.
