AbstractSeven radiocarbon dates place the regional sequence from 3000 B.C. to A.D. 1000, validate partially the method determining complexes at the site, and date the beginning of maize agriculture in the area.

The introduction of maize agriculture into the Southwest and onto the Colorado Plateau was accompanied by irrigation techniques. Twenty-six radiocarbon dates at two sites, K'yana Chabina and K'yawa:na'a Deyatchinanne, in the Zuni area of New Mexico, establish the use of irrigation canals to between 3,000 and 1,000 years ago. Associated features and the presence of nearby habitation sites independently corroborate the chronology of canal building. The geomorphology of the Zuni landscape and the morphology of the irrigation canals are consistent with the artificial construction of the canals. Pollen evidence points to an agricultural landscape and the cultivation of maize.

The timing and degree of reliance on maize agriculture in the Four Corners region of the American Southwest has been a central issue in studies that examine the origins of Puebloan society. Both diffusionist (various, but see Wills 1995) and migrationist (Berry and Berry 1986; Matson 1991) models have been proposed to explain the processes responsible for the movement of maize (Zea mays) north into the Four Corners region. This paper reports bone collagen stable carbon and nitrogen isotope values with paired accelerator radiocarbon dates on a large collection of human remains from western Basketmaker II/III sites in Marsh Pass and other areas of northeastern Arizona, as well as data on a small number of Puebloan remains including Chacoan Great House burials. The results make clear that Basketmaker II people were heavily dependent on maize by 400 B.C. Moreover, their degree of dependence is similar to that of Pueblo II and III farmers of the Four Corners region. These findings and the apparent rapidity of maize dependence support a migrationist model for the origins of maize farming in the northern Southwest.

Early Evidence

AbstractThe early evidence (2400 ± 105 B.P.) for wetland maize agriculture at the archaeological site of Fort Center, a large earth-work site in South Florida, USA, is frequently cited in discussions of the emergence of agriculture in the Eastern Woodlands of North America. The evidence for maize, however, rests on controversial pollen data; some researchers accept it, others remain skeptical of its identification or chronological placement. We present microbotanical data (pollen and phytoliths), macrobotanical data, and radiocarbon dates from recent excavations from this site. We argue that maize agriculture did not occur until the historic period at this site and that the identification of maize in earlier deposits is likely a result of contamination.

We propose that pottery-using villages did not appear in the upland Apizaco region of central Tlaxcala, Mexico, until after 1000 B.C., centuries after such developments in choice locations for maize agriculture. We excavated at two of the earliest known Formative sites in the region. That work revealed abundant intact refuse deposits, allowing us to evaluate an existing ceramic chronology with new radiocarbon dates as well as characterize Formative subsistence. Our results support a more general model of emerging sedentism in central Mexico involving population dispersions from prime agricultural areas to zones of higher elevation. The earliest pottery-using agriculturalists in Apizaco were probably migrants from adjacent regions.

Summary In 1975—76 the extra-mural bathhouse of Bothwellhaugh Roman fort near Motherwell, Lanarkshire, was completely excavated prior to flooding of the site. The bathhouse, which probably overlay a small native settlement, was in use during the Antonine phase of the Roman occupation of Scotland (AD 142—c. 165). The bathhouse consisted of a vestibule, a cold room (Frigidarium) and cold plunge bath, two warm rooms (the First and the Second Tepidarium), a hot room (Caldarium) with adjacent hot bath, and a furnace room (Praefurnium). Three main phases of use were detected. After the building ceased to function as a bathhouse, it was occupied by squatters who adapted parts of the structure to their own needs and left evidence of their presence in a large quantity of animal bone. Radiocarbon dates on this bone indicate activity in the 2nd or 3rd centuries ad.

Summary Two small burnt mounds were excavated as part of the programme to mitigate the impact of motorway construction in the Crawford area. The excavations followed a research strategy designed to address questions of date and function. This paper surveys the various competing theories about burnt mounds and how the archaeological evidence was evaluated against those theories. Both sites produced radiocarbon dates from the Bronze Age and evidence to suggest that they were cooking places. In addition, a short account is presented of two further burnt mounds discovered during the construction of the motorway in Annandale.

Summary An archaeological excavation was carried out at Graham Street, Leith, Edinburgh by Glasgow University Archaeological Research Division (GUARD) as part of the Historic Scotland Human Remains Call-off Contract following the discovery of human remains during machine excavation of a foundation trench for a new housing development. Excavation demonstrated that the burial was that of a young adult male who had been interred in a supine position with his head orientated towards the north. Radiocarbon dates obtained from a right tibia suggest the individual died between the 15th and 17th centuries AD. Little contextual information exists in documentary or cartographic sources to supplement this scant physical evidence. Accordingly, it is difficult to further refine the context of burial, although a possible link with a historically attested siege or a plague cannot be discounted.

Summary A palisaded enclosure and associated features were excavated by CFA Archaeology Ltd (CFA) in advance of the construction of the proposed Glasgow Southern Orbital Road. Radiocarbon dates indicate that the palisade and at least some of the internal features date to the Early Historic period, between the 8th and 10th centuries cal. AD. The Titwood palisade is currently the only site of this date to have been excavated in western mainland Scotland, as well as being one of the few known Early Historic palisaded sites in Scotland. Evidence of Neolithic activity on the site was also established. The work was commissioned by ASH Consulting Group on behalf of East Renfrewshire Council.

This report presents the results of the excavation of a stone ford laid across the base of a small stream valley near Rough Castle, Falkirk. It was discovered during an opencast coal mining project. Radiocarbon dates and pollen analysis of deposits overlying the ford combine to indicate a date for its construction no later than the early first millennium cal BC. Interpreting this evidence was not straightforward and the report raises significant issues about site formation processes and the interpretation of radiocarbon and pollen evidence. The importance of these issues extends beyond the rarely investigated features such as fords and deserve a larger place in the archaeological literature.
