Anaschisma ("ripped up") is an extinct genus of large temnospondyls. These animals were part of the family called Metoposauridae, which filled the crocodile-like predatory niches in the late Triassic.[1] It had a large skull about 62 centimetres (24 in) long,[2] and possibly reached 3 metres (9.8 ft) long.[3] It was an ambush hunter, snapping up anything small enough to fit in its huge jaws.[3] It was very common during the Late Triassic (Norian age) in what is now the American Southwest.[4]
