RADIOCARBON DATES FOR 24PH2976, LAKE FORT PECK, PHILLIPS COUNTY, MONTANA (2009)
Charcoal from one feature and a suspected processing area at 24PH2976, a suspected Late Prehistoric communal bison kill site in the Missouri River breaks area north of Lake Fort Peck in Montana, were identified and AMS radiocarbon dated.
RADIOCARBON DATES FOR MARSH DEPOSITS FROM GC 21 AND GC 23, TOLAY CREEK, CALIFORNIA (2010)
Three samples from cores in a marshy area adjacent to Tolay Creek, California, were submitted for radiocarbon dating. Botanic components of the peat and marsh deposits were separated, then submitted for AMS dating. Three radiocarbon dates were obtained.
RADIOCARBON DATES FOR SITES 23LE174 & 23CK302, MISSOURI (2007)
One botanic sample and four sediment samples from site 23CK302 were submitted for AMS radiocarbon dating. A single botanic sample from 23LE174 also was submitted for dating. Although the original intent was to recover microscopic charcoal from all four sediment samples, visual examination of the screened portion of two of the samples revealed the presence of small pieces of coal. Coal cannot be removed from the microscopic charcoal fraction and would have caused the determination of the...
RADIOCARBON DATES ON SAMPLES FROM THE CARBON AND CLAY CORES OF A BUDDHA STATUE AND ASSOCIATED NAGA THRONE, SRI VIJAYA PERIOD STATUARY (2009)
A large, bronze Thai sculpture of a Buddha and Naga, thought to be from the Sri Vijaya Empire in southern Thailand contained carbon and clay cores, which yielded sufficient carbon for radiocarbon dating. This statuary, cast in two pieces, is reputed to be from the Sri Vijaya Empire in the late 12th to mid 13th century. Radiocarbon dating of samples from both portions of this statuary was completed to verify the dates.
RADIOCARBON DATING EARLY TRADE AND WORLD SYSTEM EXPANSION IN IROQUOIAN SOUTHERN ONTARIO, CANADA, AD 1550-1650
This dissertation establishes a new timeframe for Indigenous participation in world-system expansion in southern Ontario, Canada ca. AD 1550–1650, by investigating how and when people living in three different Indigenous Nations in southern Ontario engaged with the expanding European world-system. This will be accomplished by: 1- Establishing an absolute timeframe for the initiation and development of Indigenous-European interaction through Bayesian chronological modeling of high-precision AMS...
Radiocarbon Dating Early Trade and World System Expansion in Iroquoian Southern Ontario, Canada, AD 1550-1650 (2022)
This dissertation establishes a new timeframe for Indigenous participation in world-system expansion in southern Ontario, Canada ca.

STARCH, ORGANIC RESIDUE (FTIR) ANALYSIS, AND AMS RADIOCARBON DATING OF A CERAMIC SHERD FROM CANYON FERRY LAKE, LEWIS AND CLARK COUNTY, MONTANA (2010)
A ceramic vessel rim sherd recovered from Canyon Ferry Lake in Lewis and Clark County, Montana was submitted for starch, organic residue analysis, and AMS radiocarbon dating. The ceramic was tested for organic residues using Fourier Transform Infrared Spectroscopy (FTIR).
STARCH, PROTEIN RESIDUE, ORGANIC RESIDUE (FTIR), MACROFLORAL ANALYSIS, CHARCOAL IDENTIFICATION, AND AMS RADIOCARBON DATING OF SAMPLES FROM SITES 42JB1732, 42JB1739, 42JB1749, 42JB1760, 42JB1764, KEG MOUNTAIN RANCH, AND 42TO3974, UTAH (2011)
Lithic tools, groundstone, fire-cracked rock, charcoal, and sediment samples from sites 42JB1732, 42JB1739, 42JB1749, 42JB1760, 42JB1764, and Keg Mountain Ranch, in the Old River Bed Valley, western Utah, were submitted for starch, protein residue, organic residue, and macrofloral analyses, as well as charcoal identification and AMS radiocarbon dating. The samples were tested for organic residues using Fourier Transform Infrared Spectroscopy (FTIR). A basalt chopper from Clovis site 42TO3794,...
STRATIGRAPHIC POLLEN ANALYSIS AND AMS RADIOCARBON DATING FOR A CORE, POLLEN AND STARCH ANALYSIS OF GROUNDSTONE AND A SOIL SAMPLE, AND AMS RADIOCARBON DATING OF CHARCOAL SAMPLES FROM THE BLACKFOOT CAVE (SITE 5DA2358), COLORADO (2014)
Sixteen pollen samples were examined from a core taken at the Blackfoot Cave site, 5DA2358, in southeast Douglas County, Colorado. This rock shelter is unusual in that it has a permanent spring flowing from it, making it a very desirable location for extensive prehistoric and historic use. In 1859, the first house was built at the site. Artifacts attest to Archaic through Historic occupations. The core was taken from a small wetland area in the catch basin of the spring below the cave and...

Fieldwork from the 1989-90 seasons at La Quemada
WOOD AND CHARCOAL IDENTIFICATION AND AMS RADIOCARBON DATING OF SAMPLES FROM B. F. SISK DAM, CALIFORNIA (2009)
Two wood samples and eight charcoal samples were submitted for identification and AMS radiocarbon dating. These samples were collected from Bench 5 and Bench 4 at the B. F. Sisk Dam in central California. Samples were identified, and radiocarbon dates were obtained on nine samples.
XAD PURIFICATION AND RADIOCARBON DATING OF BONE FROM CUNCAICHA ROCKSHELTER, PERUXAD PURIFICATION AND RADIOCARBON DATING OF BONE FROM CUNCAICHA ROCKSHELTER, PERU (2012)
Three samples of bone collected from Cuncaicha Rockshelter in Peru were pulverized at the University of Arizona and received for XAD purification and AMS radiocarbon dating. These samples represent three unique specimens identified as vicuña (Vicuna mensalis) or Andean deer (Hippocamelus antisensis).
