The Spore Conundrum: Does a Dung Fungus Decline Signal Humans’ Arrival in the Eastern US?
Author(s): Stuart Fiedel
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 explained?
