The carbon and clay cores of two sculptures were submitted for AMS radiocarbon dating. A bronze Brahmanic sculpture of Vishnu was purportedly made during the Sukhothai era in Thailand. These pieces are noted to have been produced from the 1300s until the first quarter of the 1500s. A bronze sitting Buddha from Bhutan was supposedly cast during the 1400s. Radiocarbon dating of samples from both statues was completed to verify the dates.

Fragments of Thuja plicata (western red cedar) bark from the High Bar Cache, site 10IH3488, in Hells Canyon, Idaho, were submitted for AMS radiocarbon dating. This cache consists of a greenstone pestle, a wooden tool, and textiles stored under a cairn in a boulder overhang, which is believed to represent a cache of a woman’s equipment and possessions. AMS radiocarbon dates were obtained on fragments of inner cedar bark from a woven mat and from a large bundle of bark.

A stone pipe stem recovered from the Hurdy Gurdy Bridge Site (CA-DNO-1028) in Del Norte County, northwestern California, was examined for pollen, phytolith, and starch evidence of use. In addition, the organic residue signature was examined using Fourier transform infrared spectroscopy (FTIR). An AMS radiocarbon date was obtained on organic compounds (humates) that had penetrated the ceramic matrix of the pipe.

During field excavations in February 2016, numerous stratigraphic sediment samples were collected. Three of these were selected for AMS radiocarbon analysis to include dates on both shell and organics in the form of humates (soil organic matter or SOM) or charcoal, if any could be recovered. Sufficient quantities of sediments were collected from each location to allow pollen and/or phytolith analysis, either as part of the first batch of samples examined or for examination at a later date. In...

The Topliff Fault is a north-trending fault zone in the Rush Valley of Tooele County, Utah. Geological research along the fault at the Topliff Hill Site aims to better understand prehistoric earthquakes. In association with ongoing research, samples were submitted for bulk sediment analysis and AMS radiocarbon age determination, with the goal of providing a timeline of earthquakes at the fault.

The Warm Springs Valley Fault is a strike-slip fault in the northern Walker Lane, Washoe County, Nevada. In the autumn of 2018, a team from the University of Nevada, Reno (UNR) opened a trench across the Warm Springs Valley Fault. The objectives of the UNR geologists is to better understand the timing and recurrences of earthquakes related to the fault. Three sediment samples (Samples WSV_C14#11, WSV_C14#10, and WSV_C14#9) were submitted to PaleoResearch Institute by UNR to recover charcoal for...

Three ceramic sherds, 29-88-5, 29-88-6, and 29-92-1, were submitted for ceramic analysis. The Promontory Gray sherds, samples 29-88-5 and 29-88-6, were fragments of a Promontory gray globular-shaped jar that would have measured roughly 18 to 20 cm in diameter and roughly 15 cm in height when intact. This vessel was presumed to have been used as a bone grease rendering vessel and dated between A.D. 1450 and 1650. Both sherds (29-88-5 and 29-88-6) were treated as a single sherd sample. The third...

Three ceramic sherds with visible charred residue were submitted for phytolith, starch, and AMS radiocarbon dating analyses. These items were recovered from site 8BY1347, a shell midden site located on the Tyndall Air Force Base near Panama City, Florida. These analyses are used to determine the age of the artifacts and to identify some of the foods that might have been cooked or stored using the vessels represented by these sherds.

Site 34MC1149 is located on U.S. Army Corps of Engineers fee-owned lands at Pine Creek Lake, 21 km northeast of the town of Fort Towson, Oklahoma. When the site was occupied in the Late Sanders (ca. AD 1200–1300) and McCurtain phases (ca. AD 1300–1700), it was situated on an upland landform overlooking the Little River Valley (Shannon R. Ryan, personal communication, January 21, 2019). R. Christopher Goodwin & Associates (RCG&A) submitted a nearly complete ceramic vessel (Sample 1) to...

The River Farm site (18AN881) exhibits Early Archaic through Late Woodland components, as well as historic use. It is situated on the eastern bank of the Patuxent River in Anne Arundel County, Maryland. Several features were observed, two of which were sampled for analysis. Two ceramic sherds exhibiting charred food crust and two closely associated charred botanic fragments were submitted for AMS radiocarbon analysis. Microscopic analysis of the contents of the charred food crust from both...

Two ceramic sherds from pot busts at site 8PB6, the Boca Raton Inlet Midden 3 site, in southeast Florida were submitted for analysis of residue and radiocarbon dating. Analysis of the residue for pollen, starch, and phytoliths provides an opportunity to record visual, microscopic evidence of food processing. Examination of the residue with Fourier Transform infrared spectrometry (FTIR) to obtain an infra-red spectrum provides information on the presence of lipids and di- and tri-glycerides,...

A total of nineteen bulk soil samples, fourteen detrital charcoal samples, and one wood sample from along the San Joaquin River near Fresno, California, were examined to recover organic fragments suitable for radiocarbon dating. These samples were recovered from Holocene alluvium in soil pits downstream of Friant Dam and from auger holes in slackwater deposits upstream of the dam. Botanic components and detrital charcoal were identified, and potentially radiocarbon-datable material was...
