The Manipulation of Social and Physical Identity in the Pre-Pottery Neolithic
Mortuary practices of the Pre-Pottery Neolithic Near East have been identified with skull cult and ancestor worship, as a means of creating and eliminating social boundaries. Artificial cranial modification is recognized as related to these practices, but its incidence is under-recognized and the precise nature of its significance is rarely discussed. In this study a skull, not previously reported as artificially modified, was reassessed by radio…

Hidden Treasure from the Royal Cemetery at Ur
Recent research has shed light on one of the most spectacular collections within the British Museum-the discoveries made by Sir Leonard Woolley at the Royal Cemetery of Ur. The city of Ur lies in southern Iraq and was excavated between 1922 and 1934. Its cemetery contained a group of extremely rich graves dating to around 2500 BCE. Fragile artifacts, such as bone, within these so-called Royal tombs were carefully preserved in wax to ensure their …

Metal Sources and the Bronzes From Igbo-Ukwu, Nigeria
This paper reports on a brief survey of some old copper and lead workings along the Benue Rift in SE Nigeria. Samples of lead and copper ores collected from these were analyzed to determine their lead isotope ratios for comparison with lead isotope ratios obtained from the bronzes excavated at Igbo- Ukwu. At many of these locations small-scale workings are still in operation. The lead isotope ratios of a small selection of the bronzes suggest tha…

Dating Grimes Graves
More radiocarbon analyses have been produced for the Neolithic flint mines of Grimes Graves than for any other site with which the British Museum's Radiocarbon Laboratory has been involved. Despite this heavy concentration of effort, a recent review of these figures concluded that poor sample selection, combined with a lack of sufficient quality assurance procedures, severely limit the use that can be made of this database. To overcome these diff…
Report
Recently, in an intercomparison of the Hohenheim German oak chronology (Becker 1993) and the Göttingen chronology (Leuschner and Delorme 1988), an error was discovered in the former (Leuschner, in preparation). Due to an error in adding sections at 5241 bc, 41 yr are missing in the published Hohenheim chronology. After correction of the error, the two chronologies synchronize over their entire common length, back to 7200 bc
Redating Rams Hill and reconsidering Bronze Age enclosure
A new set of radiocarbon measurements for the three phases of Bronze Age enclosure at Rams Hill allows refinement of their chronology. Phase 1 is radiocarbon dated for the first time and appears, contrary to previous indications, not to be very much earlier than phases 2 and 3. The dates are on carefully selected bone samples and give a rather later timespan overall than an earlier set of dates on charcoal, within the 13th–10th centuries cal BC. …
British Museum Natural Radiocarbon Measurements XXIII
The following list consists of dates for archaeological samples measured mostly between October 1989 and November 1990. Charcoal and grain samples were pretreated with 1M HC1 followed by washing in water and, in the majority of cases, with dilute alkali for the removal of humic acids. Wood samples were treated in the same way, or, if large enough, reduced to cellulose with chlorine dioxide produced in situ. Antler and bone samples were treated wi…
Radiocarbon Results for the British Beakers
The beginning of the Bronze Age in the British Isles has traditionally been marked by the appearance, in the archaeological record, of Beaker assemblages, mainly characterized by the Beaker pottery form itself. Ceramic typologies based on this style, which is undoubtedly continental in origin, have been used both for relative dating and as evidence of the social and economic developments of the period. Systematic radiocarbon dating has been attem…

Wood samples were treated either in the same way, or, where large enough, were reduced to cellulose by the action…

Radiocarbon Dates for Tell Brak, 1987
Four samples from Tell Brak were analysed for radiocarbon content at the British Museum Research Laboratory in 1987, with the results given below (Ambers et al., 1989). All results are quoted in the form recommended by Stuiver and Polach (1977) in uncalibrated years BP (before 1950) and corrected for measured δ13C variation. Calibrations are given based on 1σ error terms, following the curves of Pearson and Stuiver (1986) and Pearson et al. (1986…

Preliminary Statement on an Error in British Museum Radiocarbon Dates (BM-1700 to BM-2315)
A systematic error has been identified in radiocarbon measurements run in the British Museum laboratory between approximately mid 1980 and the end of 1984, when all dating was halted for a number of months. The measurements potentially affected have numbers between about BM- 1700 and BM-2315, and correspond roughly to date lists XV to XIX pub- lished in Radiocarbon. The error is systematic, giving dates that are too young by varying amounts: some…

Detection of Bias in the Background of Vials Used for Radiocarbon Dating
Inter-vial variation in background of the glass vials used in liquid scintillation counting can introduce appreciable errors into 14 C measurements. Our aim was to measure the background in each of 50 glass vials, under the same conditions as far as possible, in order to find a self-consistent set for use in 14 C dating. The criteria, statistical tests, and possible errors introduced by not making such checks are discussed
