Big Bone Lick in northern Kentucky has been a critical site in the historical development of North American Quaternary vertebrate paleontology and archaeology since the 1700s. Solid-sediment cores, stream profile excavations, vertebrate paleontology, archaeology, accelerator mass spectrometry radiocarbon and optically stimulated luminescence dating, and stable carbon and nitrogen isotope analyses were undertaken to address the lack of a modern study of the Quaternary chronostratigraphy and to...

In pond sediments in Ohio, Indiana, and New York, Sporormiella (dung-fungus) spore declines at ca. 14,000 cal BP are followed first by charcoal particle peaks, and then dramatic shifts in tree pollen percentages. This sequence has been interpreted as the outcome of initial human predation on megafauna. New dates push "classic" Clovis back to ca. 13,500 cal BP, but this still leaves a 500-yr gap between the ecological signals and the earliest Paleoindian artifacts. How can this gap be...
