Faunal lists of taxa from the continental Permian and Triassic vertebrate localities from Algeria (Zarzaitine Series) and Morocco (Argana Group) are reported and their stratigraphical implications discussed. The nectridean Diplocaulus minimus and a captorhinid moradisaurine support a Permian age (Ufimian-Kazanian) for the top of Member T2 of the Argana Group. The base of the Lower Sandstones of the Zarzaitine Series is considered Late Spathian-Lower Anisian on the basis of capitosaurid, trematosaurid, benthosuchid and brachyopoid amphibians. Both these localities have yielded Upper Triassic vertebrates. The aetosaurs ( Paratypothorax, Desmatosuchus ) support a Late Carnian age for the top of the Lower Sandstones, whereas metoposaurs, parasuchians, an aetosaur and a Placerias -like form are indicative of Middle to early Late Carnian age for Member T5 of the Argana Group.

Three incomplete dorsal lateral scutes from the Irohalene member of the Timesgadiouine Formation, Argana Group in the Essaouira basin of Morocco can be assigned to Longosuchus meadei (Sawin). This supports correlation of the vertebrate fossil assemblage of the Irohalene Member, which also includes Paleorhinus, Angistorhinus and Placerias, to the Otischalkian and Sanfordian land-vertebrate faunachrons of the North American Late Triassic. The Irohalene Member, therefore, is of Late Carnian (late Tuvalian) age.
