Carcass acquisition and consumption by carnivores and hominins in Middle Pleistocene sites of Casablanca (Morocco)
Résumé
Study of faunal series resulting from recent excavations in two caves in North Atlantic Morocco (Grotte à Hominidés - GH - and Grotte des Rhinocéros - GDR - at Thomas I and Oulad Hamida 1 quarries, Casablanca) has yielded new evidence concerning the gathering and processing of ungulates carcasses during the Middle Pleistocene in this part of North Africa. Preliminary taphonomic analysis of the macrofauna indicates that the carcasses were mainly introduced in the caves by carnivores. Additionally, marks generated by porcupines also occur. Dimensions and morphologies of tooth-marks and coprolites suggest that carnivores of different sizes (mainly middle-sized canids, hyenids and felids), as well as porcupines, used the cave. Cut-marks on the bones are absent at GH and scarce at GDR, despite their association with lithic artefacts and human fossils. This raises the question of the relationship between hominins and other competitors in these caves. The recurring question is to determine the modalities of niche partitioning by the various predators and/or carrion-eaters as well as the mode of introduction of artefacts and human remains.
