New lithostratigraphic and chronostratigraphic data for the fossil human skull-bearing eolianite of Rabat-Kebibat (Morocco)

Abstract

The Kebibat quarry locates on the coastal area of Rabat. It is also known as ''The Rabat Human deposit'' due to the presence of human cranial bones in the quarry deposit. These remains of Hominines are related to the archaic Homo sapiens.The revision of the geological and geochronological context of Kebibat and its surroundings allowed clarifying the morpholitho-stratigraphic aspects of the different formations that constitute it, as well as their evolution during the Middle-Upper Pleistocene. The sedimentary unit that fossilized the human remains corresponds to a dune deposit (eolianite), which is part of a high-resolution sedimentary sequence (parasequence). Luminescence and U-Th dating indicate that this sequence was deposited between the end of the marine isotopic stage 7 (MIS 7) until the end of MIS 6.

The relevance of late MSA mandibles on the emergence of modern morphology in Northern Africa

“…The geologic provenance of this so-called “Rabat Man” could be tracked via an imprint of the palate and its molars in the calcarenite limestone. The associated sedimentary unit 2 from sequence 2 was dated by Infrared Stimulated Luminescence (IRSL) to 137 ± 7 ka BP 32 , which is in line with previous dating attempts of an underlying marine shell layer 33 . The Kébibat human remains (Fig.…”
