The 14,200-Year-Old Human DNA Found In Ancient Feces — And The Oregon Cave Discovery That Challenged Clovis
The multi-period occupation documented in the Paisley sediment record is consistent with a pattern of regular, repeated use of a known, valued location — not a random encounter with an unknown cave, but a deliberate visit to a place that had been part of the community’s knowledge for generations.
The dietary content of the Paisley coprolites contributes to understanding what these people were eating and how they were exploiting the resources of the lake basin.
The plant remains identifiable in the coprolites include species consistent with the Great Basin flora of the late Pleistocene.
The presence of specific seed types and plant parts that require processing — grinding, soaking, or heating to be digestible — indicates that the Paisley people were not simply consuming raw plant foods but were applying the processing knowledge necessary to make otherwise indigestible or toxic plant materials edible.
This processing knowledge is another form of technological sophistication that is easy to overlook in discussions focused on stone tools.
