Laosuchus naga (Arbez, Sidor and Steyer 2018; Permian-Triassic boundary) is known from a long-snouted, flat skull with raised posterior orbits. Originally it was considered a chroniosuchid. Here Laosuchus nests with Sahrastega and Nigerpeton.

Saharastega moradiensis (Sidor et al. 2005, Damiani 2006; Late Permian, 250 mya) is a large, flat-headed, temnospondyl basal tetrapod. According to the original reconstruction it is the only temnospondyl in the large reptile tree in which the jugal has no posterior process and the quadratojugal contacts the postorbital. A new identification of those bones is shown above that remove those autapomorphies and locate a pair of nares at mid rostrum. Which means the anterior openings are fang holes, as in Nigerpeton (below).

Nigerpeton ricqlesi (Sidor et al. 2005; Late Permian, 250 mya) is a late-surviving temnospondyl with displaced nares at mid rostrum, fang holes at the rostrum tip and a very short cranium.
