Carcharodontosauridae Stromer 1931

Carcharodontosauridae At least two species are known from the Kem Kem Group (although some studies consider only one species— Ibrahim et al. 2020a). A nearly complete skull and some vertebral elements of Carcharodontosaurus saharicus were described by Sereno et al. (1996), in which a neotype was designated, recovered from the Douira Formation, south-eastern Morocco (Sereno et al. 1996, Ibrahim et al. 2020a). An isolated and fragmentary portion of a dentary [originally referred to an abelisaurid by Russell (1996) —see Ibrahim et al. (2020a)] can also be assigned to C. saharicus. A second carcharodontosaurid species, Sauroniops pachytholus, was erected by Cau et al. (2013) based on an almost complete frontal. Later on, Paterna and Cau (2023) also referred additional materials (a partial maxilla and a jugal) to Carcharodontosauridae, discussing the status of both— Carcharodontosaurus and Sauroniops. A probably indeterminate carcharodontosaurids manual ungual [Ibrahim et al. (2020a), originally described as Theropoda indet. by Russell (1996)] adds to the fossil record of this clade. Here we also provided the description of an isolated ischium we identify as an indeterminate carcharodontosaurid (NHMUK PV R 16437), adding to the fossil record of this clade from the Kem Kem Group.
