Abstract

The Singa (Sudan) calvaria has been interpreted previously as a terminal Pleistocene modem human fossil, perhaps related to the Bushman of Southern Africa. Here we report new mass-spectrometric U-Th dates for the calcrete deposit enclosing the fossil teeth and the calvaria itself and new electron spin resonance (ESR) dates for associated dental materials. The new data constrain the age of the hominid to at least 133 +/- 2 ka. Together with the preferred linear uptake (LU) ESR dates, the U-Th data confirm that the intriguing mixture of modern and archaic characteristics in the Singa specimen date from isotope stage 6. Far from being a modern human fossil, it represents a rare example of an archaic African population which may have been ancestral to all modern Homo sapiens. (C) 1996 Academic Press Limited
