A bone fragment from the Folsom layer at the MacHaffie site (24JF4) was submitted for collagen recovery and an AMS radiocarbon date. After this analysis an additional bison bone fragment was submitted for subsequent collagen recovery and an AMS radiocarbon date. The MacHaffie site is situated on the western slopes of the Elkhorn Mountains in west-central Montana. Paleoindian sequences contained within floodplain alluvium include a Folsom deposit with an estimated age of 10,425 radiocarbon years...

This dataset contains information for 104 AMS radiocarbon dates from nine Attiwandaron and Tionontate sites in southern Ontario, Canada. Contextual information and information regarding how samples are related to one another is included. This same dataset will be uploaded to CARD (the Canadian Archaeological Radiocarbon Database) after a 2-year data embargo (in 2025).

Sheep Rock Spring (24JF292) is a deeply stratified Middle to Early Precontact occupation site located northeast of Whitehall in Jefferson County, Montana. This stratified alluvial/colluvial locality is situated on the southeast-facing slope of Bull Mountain near Sheep Rock Spring in the Sheep Creek Valley. The spring is currently used as a water source for cattle. The existing radiocarbon chronology on bone indicates that the zone of fluctuating water table has introduced contaminants (Wilson...

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...

Five charred Zea mays (corn) cob fragments and one charred Phaseolus vulgaris (bean) fragment recovered from two room blocks and a kiva at the Pigg Site (5MT4802) in Montezuma County, Colorado, were submitted for identification verification and AMS radiocarbon dating. Also submitted for organic residue analysis were several painted ceramic mug fragments that were used to line a sipapu in the same kiva from which the corn and bean samples were recovered. Organic residue analysis on select sherds...

A Besant phase potsherd with visible residue from site 24LT505 was submitted for AMS radiocarbon dating and phytolith and starch grain analysis. Radiocarbon dating the charred residue provides information on when the vessel represented by this sherd was primarily in use. Phytolith and starch grain analysis provides information on some of the foods prepared or stored within the vessel.

Charcoal recovered from an intact midden deposit at site DcRu-63 on southern Vancouver Island, British Columbia, was submitted for identification and AMS radiocarbon dating. Site DcRu-63 is a large shell midden occupation site. AMS radiocarbon dating was undertaken because the age of the site is currently unknown.

Two pieces of bone from site 25FT376 were submitted for AMS radiocarbon dating. This site reflects a remnant of a Holocene terrace on an island in Hugh Butler Lake (Red Willow Lake) in Frontier County, Nebraska. This island is usually under water in the reservoir, but has been exposed during draw-down of the reservoir for repairs to Red Willow Dam. The island surface contains a scatter of bison bone, chipped stone tools, and lithic debitage. Site 25FT376 is believed to reflect an Early Archaic,...

Three bone fragments from Site CA-SDI-1313/14791 were submitted for AMS radiocarbon dating. This site is located on Marine Corps Base Camp Pendleton in northern San Diego County, southern California. These bone fragments are expected to date between 6800-3000 BP. Sufficient collagen was recovered from only one of the bone fragments; therefore, an additional three bone samples were submitted. A total of four dates were obtained.
