Abstract
We tried in the present study to apply the electron spin resonance method ESR combined with uranium-series method US for dating fossilized human teeth and found valuable archaeological sites such as Karain Cave in Anatolia. Karain Cave is a crucial site in a region that has yielded remains of Neanderthals and Homo sapiens our direct ancestors. The dating of these remains allowed us to trace the history since the presence of man on earth. Indeed Anatolia in Turkey is an important region of the world because it represents a passage between Africa the Middle East and Europe. Our study was conducted on faunal teeth found near human remains. The combination of ESR and US data on the teeth provides an understanding of their complex geochemical evolution and get better estimated results. Our samples were taken from the central cutting where geological layers are divided into archaeological horizons each 10 cm. The AH4 horizon of I.3 layer which represents the boundary between the Middle Paleolithic and Upper Paleolithic is dated to 29 4 ka by the ESR-US model. Below two horizons AH6 and AH8 in the same layer I.4 are dated respectively 40 6 and 45 7 ka using the ESR-US model. In layer II where a stalagmite floor was taken we made two U-Th dating at the base and on the top ages oscillated around 120 ka. Since human remains were collected from AH3 horizon for Homo sapiens and AH5 and AH7 horizons for the Neanderthal man so the dates obtained in AH4 AH6 and AH8 represent maximum ages. Thus they provide the disappearance of Neanderthal man between 45 and 40 ka and the appearance of Homo sapiens in 29 ka in Anatolia region. Undoubtedly there is a chronological gap between the Middle and Upper Paleolithic represented by the disappearance of Neanderthals and the appearance of sapiens and none of our results confirm the contemporaneity of these two species in this region.
