Abelisauridae, Bonaparte & Novas, 1985

Abelisauridae

The fossil record of abelisaurids is one of the most abundant in the Kem Kem Group, being less abundant only than spinosaurids. Russell (1996) described several bone fragments, including two partial right dentaries, in addition to two partial cervical vertebrae that were attributed to an undetermined theropod, but recently were assigned to abelisaurids ( Souza-Júnior et al. 2023). Although the locality from which these materials were derived is unknown, they were probably recovered from the Cenomanian of southern Morocco ( Souza-Júnior et al. 2023). A partially preserved maxilla that probably comes from Erfoud was described by Mahler (2005). Novas et al. (2005) related a ungual pedal to Abelisauroidea from the Tafilalt region. A partially preserved left maxilla that derives from a region near Taouz was described by Porchetti et al. (2011). The proximal part of a femur was described by Chiarenza and Cau (2016). In addition to these, an axis vertebra described by Smyth et al. (2020a) was also attributed to Abelisauridae .
