The preservation of fiber artifacts at Paisley Caves is exceptional precisely because of the same conditions that preserved the coprolites.

Dry alkaline caves in arid environments are among the most favorable contexts for the preservation of organic materials, and the archaeological record of the Great Basin and surrounding regions has produced some of the best-preserved examples of early fiber technology anywhere in the Western Hemisphere.

The age of the Paisley fiber evidence — whether it clearly predates Clovis or falls within the Clovis age range — is a question that requires careful stratigraphic attribution and dating.

The materials reported in the Jenkins research program have been dated as part of the broader radiocarbon chronological framework for the site, and their relationship to the pre-Clovis layers has been part of the overall argument for early occupation.
