Electron spin resonance dating of vertebrate remains from the Pestera cu Oase
To provide an additional radiometric dating window on the ages of the cave bear and other vertebrate remains and their contexts, electron spin resonance (ESR) analysis was undertaken for nineteen samples. These samples came from the surfaces of the Galeria celor Trei Cranii, the Galeria Lunga, and the Galeria Culcu§urilor, from the surface and within the bone bed of the Panta Stdimo§ilor, and from within the stratigraphy of the Putul. In each case the samples were of permanent teeth associated with bone and adherent sediment. A total of 17 of the samples were of Ursus spelaeus remains, and the last two derived one each from Cervus elaphus and Canis lupus.
