Hominid Cave at Thomas Quarry I (Casablanca, Morocco): recent findings and their context.

Abstract : The Thomas Quarry I, first investigated by P. Biberson (1961a and b), was made famous in 1969 with the discovery by Ph. Beriro of a half-mandible, first attributed to Atlanthropus mauritanicus by Ennouchi (1969), but more recently considered as a representative of Homo rhodesiensis (Hublin, 2001). Four teeth of Homo have been recovered in stratigraphic unit 4 between 1994 and 2005. The first right upper premolar discovered in 1994 has been dated using laser ablation ICP-MS. Combining the ESR and U-series data for the modelling of the U-uptake (Grün et al. 1988), an US/ESR age of 501+94 -76 ka is obtained (with associated p-values of 1.43 ± 0.59 and 0.75 ± 0.45 for enamel and dentine, respectively).
