POLLEN AND PHYTOLITH ANALYSIS OF COPROLITE SAMPLES FROM YAKUTIA, RUSSIA AND THE PONTATOC RIDGE SHELTER, ARIZONA, USA (2018)

DOCUMENT Full-Text Linda Scott Cummings.

Dung from locations in Arizona and Russia were submitted for pollen and phytolith analysis. Pontatoc Ridge Shelter exhibited a surface mat dating approximately 14,000 yr BP. Dung recovered from a pica nest in permafrost in association with Pleistocene-age mammals such as mammoth and rhino. Analysis of microscopic remains (pollen and phytoliths) was undertaken to identify local vegetation at the time each of these dung deposits accumulated.
