Kem Kem Beds nebo Kem Kem Group ("skupina Kem Kem") je název geologické skupiny sestávající ze dvou souvrství, jejichž výchozy se nacházejí na území Maroka a Alžíru. Tato geologická formace je známá objevy fosilií dinosaurů a dalších křídových živočichů. Stáří sedimentů činí asi 98 až 92 milionů let, pocházejí tedy z období geologických věků cenoman a turon. Jednalo se o prostředí se značnou biodiverzitou, významným taxonem byl například obří teropod Spinosaurus.

(ar) The Kem Kem Group (commonly known as the Kem Kem beds) is a geological group in the Kem Kem region of eastern Morocco, whose strata date back to the Cenomanian stage of the Late Cretaceous. Its strata are subdivided into two geological formations, the lower and the upper . It is exposed on an escarpment along the Algeria–Morocco border. The unit unconformably overlies Paleozoic marine units of Cambrian, Silurian and Devonian age, and is itself capped by limestone platform rock of Cenomanian-Turonian age. It primarily consists of deltaic deposits. The lower Gara Sbaa Formation primarily consists of fine and medium grained sandstone, while the Douira Formation consists of fining-upwards, coarse-to-fine grained sandstones intercalated with siltstones, variegated mudstones, and occasional thin gypsiferous evaporites. Dinosaur remains are among the fossils that have been recovered from the group. 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 be separated by millions of years. (en) Les Kem Kem sont un vaste plateau rocheux tabulaire semi-désertique (ou hamada) et un site paléontologique situé sur la frontière marocco-algérienne. Il ne se délimite clairement que d’un point de vue géologique. (fr) I Kem Kem Beds (indicato anche come, Continental Red Beds e Continental intercalaire) è una formazione geologica situata lungo il confine tra il Marocco e l'Algeria, i cui strati risalgono al Cretaceo superiore. Nella formazione sono stati raccolti molti resti fossili di vertebrati, tra cui: dinosauri, coccodrilli, pterosauri e una grande varietà di pesci e creature acquatiche. Recenti prove fossili sotto forma di grandi esemplari fossili di abelisauridi isolati, e confronti con altre formazioni di età simile, sempre in Africa indicano che la fauna del Kem Kem Beds (in particolare per quanto riguarda i numerosi dinosauri teropodi predatori) potrebbero essere stata mescolata insieme a causa della geologia mutevole della regione, quando in realtà una così vasta concentrazione di teropodi predatori avrebbero probabilmente preferito habitat separati e oltre che essere separati tra loro da milioni di anni.
