AMS RADIOCARBON DATING AND ORGANIC RESIDUE (FTIR) ANALYSIS OF SAMPLES FROM SITE 14OT5-H2, OTTAWA COUNTY, KANSAS (2013)
DOCUMENT Full-Text Linda Scott Cummings. Peter Kováčik.

A possible bison bone fragment was recovered from House 2 of the Minneapolis site, 14OT5, situated in Ottawa County, Kansas. An AMS radiocarbon date of 1070 ± 15 RCYBP had been obtained on ceramic residue from this site, but was not a credible age for this context. Therefore, a fragment from the long bone shaft was submitted for AMS radiocarbon dating to obtain a context date to corroborate or refute the residue date; however, no collagen was present. As a result, charred residue from a ceramic...
