The lower Gara Sbaa Formation primarily consists of fine and medium grained sandstone, while the Douira Formation consists of fining-upward, coarse-to-fine grained sandstones intercalated with siltstones, variegated mudstones, and occasional thin gypsiferous evaporites.

[3] Recent fossil evidence in the form of isolated large abelisaurid bones and comparisons with other similarly aged deposits elsewhere in Africa indicates that the fauna of the Kem Kem Group (specifically in regard to the numerous predatory theropod dinosaurs) may have been mixed together due to the harsh and changing geology of the region, when in reality they would likely have preferred separate habitats and likely would have been separated by millions of years.

An iguanian belonging to the group Acrodonta, possibly a relative of the uromastycine agamids.

Argued by Vullo et al. (2022) to actually come from Quaternary beds, and to be based on a fossil material of a member of the genus Uromastyx.

[31] Indeterminate lithostrotian remains once misattributed to the Titanosauridae are present in the province of Ksar-es-Souk, Morocco.

[34] The ischium is not identifiable beyond Somphospondyli; it preserves numerous grooves and pits which might be feeding traces left by a very large non-avian theropod.

[34] Titanosauria[35][1] Indeterminate Isolated teeth, caudal vertebrae, a partial humerus, a tarsal bone and the proximal end of an ulna.

Some fossils are indicative of large body size comparable to Paralititan stromeri.

Hendrickx et al. (2024) reinterpreted this fossil material as teeth of abelisauroid theropods, including noasaurids and juvenile abelisaurids.

Sauroniops[45] S. pachytholus "An isolated and almost complete left frontal,[46] and a possible tooth and neural arch from two other specimens.

Originally believed to belong to either the family Thalassodromidae[51] or an additional specimen of Alanqa saharica.

[58] Nicorhynchus[57] N. fluviferox[59][57] Possibly Aferdou N’Chaft, Hassi El Begaa[57] An anterior portion of the rostrum.
