Description :
This paper reports AMS C 14 ages of 10 bones and teeth of 3 species of large mammals from the Dutchess Quarry Caves, New York. Together with the Holocene conventional C 14 dates of charcoal and the varied stratigraphic proveniences of the fluted points and the dated bones, the new AMS C 14 dates argue that most strata at the Dutchess Quarry Caves contain a mixture of late Pleistocene and Holocene materials. This mixing probably resulted from post-depositional bioturbation (by humans, rodents, carnivores, and scavengers) and cryoturbation (annual freeze-thaw cycles).
