AbstractThe paper reports on the fourth (2010) season of fieldwork of the Cyrenaican Prehistory Project, and on further results of analyses of artefacts and organic materials collected in the 2009 season. Ground-based LiDar has provided both an accurate 3D scan of the Haua Fteah cave and information on the cave's morphometry or origins. The excavations in the cave focussed on Middle Palaeolithic or Middle Stone Age ‘Pre-Aurignacian’ layers below the base of the Middle Trench beside the McBurney Deep Sounding (Trench D) and on Final Palaeolithic ‘Oranian’ layers beside the upper part of the Middle Trench (Trench M). Although McBurney referred to the upper part of the Deep Sounding as more or less sterile, the 2010 excavations found evidence for small-scale but regular human presence in the form of stone artefacts and debitage, though given the sedimentary context the latter are unlikely to represent in situ knapping. The excavations of Trench M extended from the basal Capsian layers investigated in 2009 through Oranian layers to the transition with the Dabban Upper Palaeolithic. Some 17,000 lithic pieces have been studied from the Capsian and Oranian layers excavated in Trench M, in an area measuring less than 2 m by 1 m by 1.1 m deep, along with numerous animal bones, molluscs, and macrobotanical remains, as well as occasional shell beads. Preliminary studies of the lithics, bones, molluscs, and plant remains are revealing the changing character of late Pleistocene (Oranian) and early Holocene (Capsian) occupation in the Haua Fteah. Alongside the work in the Haua Fteah, the project continued its assessment of the Quaternary and archaeological sequences of the Cyrenaican coastland and completed a transect survey of surface lithic materials and their landform contexts from the pre-desert across the Gebel Akhdar to the coast, with a new focus on the al-Marj basin. Significant differences are emerging in patterns of Middle Palaeolithic and later hominin occupation and palaeodemography.

AbstractThe paper reports on the fifth (2012) season of fieldwork of the Cyrenaican Prehistory Project. The primary focus of the season was the continuation of the excavation of the prehistoric occupation layers in the Haua Fteah cave. A small trench (Trench U) was cut into Holocene (Neolithic) sediments exposed on the south wall of Charles McBurney's Upper Trench. Below this, the excavation of Trench M was continued, on the southern side of McBurney's Middle Trench. In previous seasons we had excavated Oranian ‘Epipalaeolithic’ layers dating toc.18,000–10,000 BP (years before the present). In 2012 the excavation continued downwards through Dabban ‘Upper Palaeolithic’ occupation layers, one of which was associated with a post-built structure and likely hearths. There are indications of an occupational hiatus separating the oldest Dabban from the youngest Levallois-Mousterian (Middle Palaeolithic or Middle Stone Age) lithic material. The Deep Sounding excavated by Charles McBurney in 1955 was cleared of backfill to its base, and its south-facing wall was recorded in detail and sampled extensively for materials for dating and palaeoenvironmental reconstruction. McBurney believed that he had reached bedrock at the base of the Deep Sounding, but a small sounding (Trench S) cut into the sediments below this level found further, albeit sparse, evidence for human occupation. Whilst the antiquity of ‘Pre-Aurignacian’ human occupation at the site still needs to be resolved, it seems likely to reach back at least to Marine Isotope Stage 5e, the beginning of the last interglacial (c.130,000–115,000 BP). Important finds from the 2012 excavations in terms of the behavioural complexity of the human groups using the cave include a possible worked bone point from a Pre-Aurignacian layer and a granite rubbing stone in a Dabban layer from a source over 600 km from the cave.

Flotation Technique

AbstractThis paper outlines the procedures and equipment necessary for applying a simple flotation technique to recover animal bone, seeds, and other small cultural remains lost in the normal screening of soils from archaeological sites. Soil is initially processed in the field by a water-separation technique. The resulting concentrate is later treated, in the laboratory, by chemical flotation, to separate faunal from plant remains.This simple, inexpensive technique enables processing of soil in quantity, thereby allowing recovery of small plant and animal remains from midden or feature fills where they occur in very low densities.It is argued that, without use of such a flotation procedure, inferences about prehistoric subsistence patterns from faunal and floral remains are sharply biased in favor of larger animals and in favor of hunting, over natural plant food collecting, since conventional screens are not adequate for recovery of most plant remains or small animal bones.

Abstract. Langmuir probe electron and ion measurements from four instrumented rockets flown during the MaCWAVE (Mountain and Convective Waves Ascending VErtically) program are reported. Two of the rockets were launched from Andøya Rocket Range, Norway, in the summer of 2002. Electron scavenging by ice particulates produced reductions of the electron density in both sharp narrow (≈1–2 km) layers and as a broad (≈13 km) depletion. Small-scale irregularities were observed in the altitude regions of both types of electron depletion. The scale of the irregularities extended to wavelengths comparable to those used by ground-based radars in observing PMSE. In regions where ice particles were not present, analysis of the spectral signatures provided reasonable estimates of the energy deposition from breaking gravity waves. Two more instrumented rockets were flown from Esrange, Sweden, in January 2003. Little turbulence or energy deposition was observed during one flight, but relatively large values were observed during the other flight. The altitude distribution of the observed turbulence was consistent with observations of a semidiurnal tide and gravity wave instability effects as determined by ground-based lidar and radar measurements and by falling sphere measurements of the winds and temperatures (Goldberg et al., 2006; Williams et al., 2006).

AbstractDenisova Cave in southern Siberia is the type locality of the Denisovans, an archaic hominin group who were related to Neanderthals1–4. The dozen hominin remains recovered from the deposits also include Neanderthals5,6 and the child of a Neanderthal and a Denisovan7, which suggests that Denisova Cave was a contact zone between these archaic hominins. However, uncertainties persist about the order in which these groups appeared at the site, the timing and environmental context of hominin occupation, and the association of particular hominin groups with archaeological assemblages5,8–11. Here we report the analysis of DNA from 728 sediment samples that were collected in a grid-like manner from layers dating to the Pleistocene epoch. We retrieved ancient faunal and hominin mitochondrial (mt)DNA from 685 and 175 samples, respectively. The earliest evidence for hominin mtDNA is of Denisovans, and is associated with early Middle Palaeolithic stone tools that were deposited approximately 250,000 to 170,000 years ago; Neanderthal mtDNA first appears towards the end of this period. We detect a turnover in the mtDNA of Denisovans that coincides with changes in the composition of faunal mtDNA, and evidence that Denisovans and Neanderthals occupied the site repeatedly—possibly until, or after, the onset of the Initial Upper Palaeolithic at least 45,000 years ago, when modern human mtDNA is first recorded in the sediments.

AbstractThe paper reports on the sixth season of fieldwork of the Cyrenaican Prehistory Project (CPP) undertaken in September 2012. As in the spring 2012 season, work focussed on the Haua Fteah cave and on studies of materials excavated in previous seasons, with no fieldwork undertaken elsewhere in the Gebel Akhdar. An important discovery, in a sounding excavated below the base of McBurney's 1955 Deep Sounding (Trench S), is of a rockfall or roof collapse conceivably dating to the cold climatic regime of Marine Isotope Stage (MIS) 6 (globally dated to c. 190–130 ka) but more likely the result of a seismic event within MIS 5 (globally dated to c. 130–80 ka). The sediments and associated molluscan fauna in Trench S and in Trench D, a trench being cut down the side of the Deep Sounding, indicate that this part of the cave was at least seasonally waterlogged during the accumulation, probably during MIS 5, of the ~6.5 m of sediment cut through by the Deep Sounding. Evidence for human frequentation of the cave in this period is more or less visible depending on how close the trench area was to standing water as it fluctuated through time. Trench M, the trench being cut down the side of McBurney's Middle Trench, has now reached the depth of the latest Middle Stone Age or Middle Palaeolithic (Levalloiso-Mousterian) industries. The preliminary indications from its excavation are that the transition from the Levalloiso-Mousterian to the blade-based Upper Palaeolithic or Late Stone Age Dabban industry was complex and perhaps protracted, at a time when the climate was oscillating between warm-stage stable environmental conditions and colder and more arid environments. The estimated age of the sediments, c. 50–40 ka, places these oscillations within the earlier part of MIS 3 (globally dated to 60–24 ka), when global climates experienced rapid fluctuations as part of an overall trend to increasing aridity and cold.

In late February and early March 2002, an archaeological watching brief at Lynford Quarry, Mundford, Norfolk revealed a palaeochannel with a dark organic fill containing in situ mammoth remains and associated Mousterian stone tools and debitage buried under 2–3 m of bedded sands and gravels. Well-preserved in situ Middle Palaeolithic open air sites are very unusal in Europe and exceedingly rare within a British context. As such, the site was identified as being of national and international importance, and was subsequently excavated by the Norfolk Archaeological Unit with funding provided by English Heritage through the Aggregates Levy Sustainability Fund.This report presents some of the initial results of the excavation. It sets out how the site was excavated, outlines the stratigraphic sequence for the site, and presents some provisional findings of the excavation based on the results of the assessment work carried out by project specialists and Norfolk Archaeological Unit staff.

ABSTRACTFEBEX (Full-scale Engineered Barrier EXperiment) is a demonstration and research project dealing with the bentonite engineered barrier designed for sealing and containment of waste in a high level radioactive waste repository (HLWR). It includes two main experiments: an situ full-scale test performed at Grimsel (GTS) and a mock-up test operating since February 1997 at CIEMAT facilities in Madrid (Spain) [1,2,3]. One of the objectives of FEBEX is the development and testing of conceptual and numerical models for the thermal, hydrodynamic, and geochemical (THG) processes expected to take place in engineered clay barriers. A significant improvement in coupled THG modeling of the clay barrier has been achieved both in terms of a better understanding of THG processes and more sophisticated THG computer codes. The ability of these models to reproduce the observed THG patterns in a wide range of THG conditions enhances the confidence in their prediction capabilities. Numerical THG models of heating and hydration experiments performed on small-scale lab cells provide excellent results for temperatures, water inflow and final water content in the cells [3]. Calculated concentrations at the end of the experiments reproduce most of the patterns of measured data. In general, the fit of concentrations of dissolved species is better than that of exchanged cations. These models were later used to simulate the evolution of the large-scale experiments (in situ and mock-up). Some thermo-hydrodynamic hypotheses and bentonite parameters were slightly revised during TH calibration of the mock-up test. The results of the reference model reproduce simultaneously the observed water inflows and bentonite temperatures and relative humidities. Although the model is highly sensitive to one-at-a-time variations in model parameters, the possibility of parameter combinations leading to similar fits cannot be precluded. The TH model of the “in situ” test is based on the same bentonite TH parameters and assumptions as for the “mock-up” test. Granite parameters were slightly modified during the calibration process in order to reproduce the observed thermal and hydrodynamic evolution. The reference model captures properly relative humidities and temperatures in the bentonite [3]. It also reproduces the observed spatial distribution of water pressures and temperatures in the granite. Once calibrated the TH aspects of the model, predictions of the THG evolution of both tests were performed. Data from the dismantling of the in situ test, which is planned for the summer of 2001, will provide a unique opportunity to test and validate current THG models of the EBS.

The subject of the monograph, published as the 10th volume of the Saved Archaeological Heritage series, are the results of rescue excavations on a cemetery from the period of Roman influence on the Vistula River near Magnuszew in southern Mazovia (Poland), carried out several years ago at the initiative of the Museum in Radom. This necropolis, like many similar ones throughout the country, was systematically destroyed as a result of agricultural activities, and in recent years also through illegal prospection with the use of metal detectors. Archaeologists, with the cooperation of numerous volunteers, managed to protect against further destruction about 60 graves (urned and urnless) from the period between the 1st century BC and the 3rd century CE. These are an evidence of the settlement of the region by people whose material traces are referred to in the archaeological nomenclature as the Przeworsk culture (associated mainly with the Germanic tribes). The cinerary graves were equipped with ceramics, metal parts of clothing, tools, less often weapons, glass beads, imported vessels or dice. Among the forms of graves, the so-called groove object stands out: a kind of rectangular grave feature tied with survival to the beginnings of our era of Celtic traditions, arriving here from northern Małopolska. In addition to the standard catalogue with the description of graves, pottery and small finds, and very detailed illustration plates, the monograph includes an analysis of material culture and forms of burial, photographs of selected finds and very extensive specialist reports. The latter include both osteological materials (anatomo-anthropological analysis, analysis of animal bones placed in the graves), as well as other ecofacts and individual categories of furnishings (glass, faience, iron and bronze objects). The whole is complemented by clear plans with the location of graves and artifacts in the necropolises, as well as with the results of non-invasive research going far beyond the excavated area and of key importance for further in situ protection of this extremely valuable monument.
