America's Oldest Basketry
We have determined the earliest calibrated dates on three types of basketry from the Great Basin of western North America. The oldest twined basketry dates to 10,380–10,918 cal bp, reed duck decoys to 2355–2773 cal bp, and wooden sandals of sagebrush bark or twined tule to 9247–10,375 cal bp and 9242–9836 cal bp, respectively
Studies on Selected Proteins of Bone in Archaeology
With the advent of AMS radiocarbon dating of very small samples, a much greater opportunity now exists for research into specialized materials. Investigations of the proteins of bone and teeth for archaeological purposes suggest that much more information might be obtained by appropriate study of individual proteins in these tissues. Although present research seems limited to 14 C dating, racemization and dietary selection, conditions of the envi…
Radiocarbon Ages of Lacustrine Deposits in Volcanic Sequences of the Lomas Coloradas Area, Socorro Island, Mexico
Extensive eruptions of alkalic basalt from low-elevation fissures and vents on the southern flank of the dormant volcano, Cerro Evermann, accompanied the most recent phase of volcanic activity on Socorro Island, and created the Lomas Coloradas, a broad, gently sloping terrain comprising the southern part of the island. We obtained 14 C ages of 4690 ± 270 BP (5000–5700 cal BP) and 5040 ± 460 BP (5300–6300 cal BP) from lacustrine deposits that occu…
Radiocarbon Dating of Anodonta in the Mojave River Basin
A 450-year correction is required to make Anodonta 14 C dates comparable to 14 C dates on other materials in the Mojave River basin. The internal stratigraphic consistency of 34 conventional 14 C dates on Anodonta in this drainage basin indicates that such dates are usually reliable. The validity of most conventional 14 C dates in the Mojave River basin may be a product of the basin's crystalline bedrock in a region usually typified by thick Pale…
C Dating Mortar in Ireland
I have developed a method of dating early medieval Irish buildings using charcoal encased in mortar. Due to the inclement weather over centuries, timbers do not preserve well in these structures, leaving little suitable material for 14 C dating. Initially, several buildings of known age were analyzed to verify the mortar charcoal technique. Then, a series of buildings for which no definite architectural-historical dates existed, e.g., churches, h…

Ucla Radiocarbon Dates XI
The radiocarbon dates reported in this list are almost all based on collagen measurements from human archaeologic bone material. This collagen was isolated according to the methods developed by Berger, Horney and Libby (1964), Ho, Marcus and Berger (1969), Longin (1971) and Protsch (1973). All samples were counted as CO 2 gas at close to 1 atm in a 7.5L proportional counter with three energy channels. The 14 C dates reported are calculated with t…

Radiocarbon dating Machu Picchu, Peru
New radiocarbon dates confirm the evident possibility that Machu Picchu was not an Inca foundation on a wholly new site, and give a first indication of the duration of the citadel's previous occupation
Radiocarbon Content of Tropospheric CO 2 at China Lake, California 1977–1983
The measurements reported here are a continuation of tropospheric radiocarbon measurements in carbon dioxide carried out since 1961 at our China Lake, California collection facility. The data show a continued decrease in radiocarbon activity from ca 330‰ in 1977 to 215‰ in 1983 in agreement with similar analyses in Europe for the same time interval
Radiocarbon Concentration of California Aerosols
In this study the origin of the carbonaceous fraction of total suspended particles (TSP) in air was analyzed. While the summer data show increasing carbon concentrations in the Los Angeles air basin from west to east, in the winter high levels of carbon particles can be found over the coast. The smallest and most dangerous particle fraction is principally composed of fossil carbon
Major Revisions in the Pleistocene Age Assignments for North American Human Skeletons by C-14 Accelerator Mass Spectrometry
Radiocarbon analyses by accelerator mass spectrometric (AMS) techniques on organic fractions of human bone from various North American localities previously assigned ages ranging from about 70,000 to 15,000 years B.P. now suggest that none of these skeletons is older than 11,000 C-14 years B.P

The measurements reported in this date list form the chronometric framework for obsidian hydration and trade studies in California (Ericson, 1975; 1977; 1978; 1981; Ericson et al , 1975; Singer and Ericson, 1977). All samples were analyzed as CO 2 gas at close to 1 atm in a 7.5L proportional counter with three energy channels. Radiocarbon ages are based by convention on the 5568 ± 30 yr half-life. The biospheric standard is 95% the count rate of …
Radiocarbon Measurements of Particulates in Smog
In recent years in California, smog aerosols have been observed in metropolitan and rural areas. We wondered what the relative contribution is from sources such as fossil fuel combustion (eg, cars, factories) and emissions from trees and other plants. Pollution produced by fossil fuel combustion can be distinguished from biological sources using radioactive carbon. Carbon in fossil organic materials is radioactively dead whereas carbon in living …
Direct Bone Dating in a Small CO 2 Counter
A small 200ml capacity CO 2 proportional counting system has been developed which uses only 100mg of carbon for complete filling. Thus, with respect to the small quantities needed, it compares favorably to dedicated accelerators at significantly lower cost. The performance of this equipment is demonstrated using a variety of samples including some human bone fragments from La Jolla which had been estimated to be 28,000 years old by aspartic acid …
The Dating and Cultural Associations of the 'Potbellied' Sculptural Style
For decades the 'potbellied' monuments have been the center of a controversy in Mesoamerican archaeology. These massive boulder sculptures have been found at numerous sites associated with the major culture-historical problems of the Preclassic period in southern Mesoamerica. A secure dating of the style has not been possible and there have been several conflicting interpretations of their age and significance. One interpretation holds that some …
Radiocarbon Dating of Earthquakes
Within the United States, the State of California ranks first in recorded earthquake frequencies. Annually, thousands of shocks are registered on seismometers and many hundreds are actually noticed directly by Californians. In modern times, about one quake per year, destructive to property, has occurred, yet the very large and disastrous events approaching magnitude 8 and higher on the Richter scale are spaced a few decades apart: 1857 in Souther…
Stratigraphy, archaeology, and age of the Ndutu and Naisiusiu Beds, Olduvai Gorge, Tanzania
The upper part of the stratigraphic section of Olduvai Gorge is subdivided into the Ndutu Beds and the Naisiusiu Beds ; Beds Va and V are abandoned as stratigraphic terms. The Naisiusiu Beds are uppermost Pleistocene and give C14 dates of 10,400 to 17,550 B.P.; the Ndutu Beds are largely upper Pleistocene, but may include middle Pleistocene deposits. Faulting in the Olduvai region continued through the deposition of the Ndutu Beds, but apparently…

Advances and results in radiocarbon dating
In the early days of radiocarbon dating bone samples were found to provide often specious dates when the calcium carbonate content of bone was utilized, since it is subject to exchange reactions with ground water carbonate. With the development of collagen‐based radiocarbon dating, a number of avenues of research opened up, one of which led to the dating of a number of fossil human remains found in Southern California. Dates for Laguna woman (17,…

Electronic Data Processing for Radiocarbon Dates

The date of 'Noah's Ark
One of the most widely-known narratives contained in Judaeo-Christian literature is that of 'Noah's Ark and the Great Flood'. The version best known to most English readers is derived from the translation of Genesis VI-VIII contained in the 1611 King James Version of the Bible and its subsequent revisions. According to this account, near the end of the Biblical Deluge, the Ark rested 'upon the mountains of Ararat'. From this locality, according t…

Replacement Rates for Human Tissue from Atmospheric Radiocarbon
Carbon-14, derived from the testing of thermonuclear weapons in the atmosphere of the Northern Hemisphere during 1961-62, has been found in human tissues including the brain in amounts which reflect the atmospheric concentration of carbon-14 as of several months earlier. In collagen of cartilage, the rate of uptake of carbon-14 is much slower than in other tissues; essentially no radioactive carbon was found in the collagen of 70-year-old adults …
