ABSTRACTRadiocarbon age determinations of 32 walrus (Odobenus rosmarus) remains show that the species has been a member of the Greenland fauna since at least the middle Holocene. The oldest date is 7280–7160 calendar years BP. However, most dated remains come from archaeological sites and are of late Holocene age

The importance of chronometric dating in archaeology cannot be overemphasized. Indeed, most chronologies developed throughout the world during the past three decades have depended on radiocarbon age determinations to provide a temporal framework for examining change over time in cultural sequences during the late Pleistocene and Holocene. With the advent of legislation in the mid-1960s designed to protect archaeological sites in the United States threatened by increased urban development or government sponsored projects, archaeological surveys and excavations were mandated as a means for preserving information otherwise destroyed. As a result, thousands of projects have contributed to a growing body of “gray literature,” ie, unpublished proprietary or manuscript reports with very limited circulation. Within these reports are hundreds, if not thousands, of 14C age determinations, most of which are not accessible in published form. One objective of this paper is to present all the 14C age determinations for the island of Moloka'i, Hawai'i as of December 1988, including 41 dates never before published with stratigraphic details.

Northwest Greenland formerly supported a population of musk-ox (Ovibos moschatus). Radiocarbon dating of musk-ox remains collected on the terrain surface and from archaeological sites has yielded Late Holocene ages, indicating that the species was a late immigrant to this part of Greenland. Musk-ox arrived at a time when Greenland was uninhabited, and the species had at least several hundred years to expand and spread south, before the Late Dorset people arrived and began to hunt. The main reason that the species did not disperse south to West Greenland was probably because of the barrier presented by Melville Bugt, which was heavily glaciated in the Late Holocene. However, if there had been a longer period of time before hunting of the musk-ox occurred, there would have been an enhanced likelihood that chance dispersal south could have taken place.

Eleven radiocarbon age determinations clearly show that a lens of Holocene fluvial organic debris on the Alaskan Arctic Coastal Plain contains mostly pre-Holocene organic material. Radio-carbon ages of identified plant macrofossils indicate the material was deposited about 9000 to 9500 yr B.P. Radiocarbon analyses of bulk samples from this deposit, however, range from 13,300 to 30,300 yr B.P. Most of the old organic matter seems to be in the smaller size fractions in the deposit, particularly in the fraction between 0.25 and 0.5 mm, but all size fractions are contaminated. Particular caution must be exercised in submitting bulk samples for radiocarbon dating from areas where conditions favor redeposition of isotopically “dead” carbon.

Our understanding of prehistory is increasingly conditioned by absolute dates, particularly radiocarbon age determinations. Sample selection and date interpretation procedures are therefore important to productive archaeological research. Guidelines for those procedures are described and illustrated with archaeological examples from the Lower Mississippi Valley. Recommendations are made for the improved interpretability and reliability of absolute dates from archaeological contexts.

Northeast Greenland supports a large indigenous population of musk-oxen (Ovibosmoschatus). Radiocarbon dating of remains of this mammal collected on the terrain surface and from archaeological sites has yielded mid- and Late Holocene ages. The species probably arrived shortly before this part of Greenland became inhabited by the first hunter cultures. Only Late Holocene dates are available from the southern part of northeast Greenland, but the authors suggest that musk-ox spread south to this region at an early date, because there are no physical barriers. The lack of older dates may reflect the lack of palaeo-Eskimo sites with bones.

In this paper we evaluate the role of human strategies in the Andean Piedmont from northern Patagonia across the Holocene. Specifically, we present the analysis of the Early Holocene-Late Holocene archaeological record of Salamanca cave (Mendoza-Argentina). We identified technological changes that occurred during the Late Holocene and the implications of a human occupation hiatus in the Middle Holocene. We follow a multiproxy approach by the analysis of radiocarbon dates, archaeofaunal remains, ceramic, lithics and XRF obsidian sourcing. We also discuss a detailed stratigraphic sequence by geomorphological descriptions, the construction of a radiocarbon sequence model and summed probability distributions, compared with other archaeological sites in the region. We conclude that after the Middle Holocene archaeological hiatus, human populations grew while guanaco populations dropped. The imbalance between demography and resources boosted the incorporation of new technologies such as ceramics and the bow and arrow, allowing people to exploit lower-ranked resources.

ABSTRACTThe Thule region in north Greenland formerly supported a population of musk-oxen (Ovibos moschatus). Radiocarbon dating of bones of this mammal collected on the terrain surface and from archaeological sites has yielded late Holocene ages, indicating that the species was a late immigrant to this part of Greenland. The species may have arrived at a time when the area was uninhabited, and it had at least a thousand years to spread south, before the Late Dorset people arrived. The heavy glaciation of Melville Bugt in the late Holocene was probably the main reason that the musk-ox did not disperse south to west Greenland. The population of musk-ox in the region may have peaked during the Medieval Warm Period, and the species survived during the occupation of the region by the Late Dorset people. The size of the population may have declined during the beginning of the Little Ice Age, and musk-ox was probably exterminated from the region shortly after the arrival of the mobile Thule people.

The results of 18 radiocarbon age determinations on shelIs (14), plant material (2) and bone (2) are summarised here. The samples were collected during the GGU expedition to central and western North Greenland in 1984 (Henriksen, 1985). This list adds to the list published by Kelly & Bennike (1985). In addition, a series of dates from Hall Land and Nyeboe Land has recently been published by England (1985).

Coastal archaeological sites that lack organic remains for radiocarbon dating are often abundant sources of molluscan shells. As a substitute for materials such as bone and charcoal, shells can be analyzed with 14C dating to determine a site's age. Despite their being convenient, non-mobile archaeological artifacts, molluscan shells are plagued by several issues, including carbonate remodeling, in which aragonite in shells is converted to calcite as predicted by thermodynamics. We present here a carbonate density separation technique that addresses the issue of carbonate remodeling. Using a density fractionation with bromoform, aragonite concentrations are enriched in shells that have undergone significant remodeling. The technique has been applied to archaeological shells and has returned dates that are younger than those previously determined for the same shells.

During the late Holocene, Aboriginal rock painters in north Queensland selected and combined various natural inorganic and organic materials in paint recipes – possibly to increase the longevity of their paintings. The organic materials make direct radiocarbon dating possible.
