Arganasaurus is a temnospondyl amphibian of the Family Metoposauridae, the members of which are more commonly referred to as metoposaurs.  Their rather flat skulls bear intricate ornamentation (pits, ridges, and grooves) on the dorsal surfaces.  These animals are found in lake and river deposits and likely fed on fishes and other animals they could swallow whole.
