The 'human revolution' in lowland tropical Southeast Asia:the antiquity and behavior of anatomically modern humans at Niah Cave (Sarawak, Borneo)

Recent research in Europe, Africa, and Southeast Asia suggests that we can no longer assume a direct and exclusive link between anatomically modern humans and behavioral modernity (the 'human revolution'), and assume that the presence of either one implies the presence of the other: discussions of the emergence of cultural complexity have to proceed with greater scrutiny of the evidence on a site-by-site basis to establish secure associations between the archaeology present there and the hominins who created it. This paper presents one such case study: Niah Cave in Sarawak on the island of Borneo, famous for the discovery in 1958 in the West Mouth of the Great Cave of a modern human skull, the 'Deep Skull,' controversially associated with radiocarbon dates of ca. 40,000 years before the present. A new chronostratigraphy has been developed through a re-investigation of the lithostratigraphy left by the earlier excavations, AMS-dating using three different comparative pre-treatments including ABOX of charcoal, and U-series using the Diffusion-Absorption model applied to fragments of bones from the Deep Skull itself. Stratigraphic reasons for earlier uncertainties about the antiquity of the skull are examined, and it is shown not to be an `intrusive' artifact. It was probably excavated from fluvial-pond-desiccation deposits that accumulated episodically in a shallow basin immediately behind the cave entrance lip, in a climate that ranged from times of comparative aridity with complete desiccation, to episodes of greater surface wetness, changes attributed to regional climatic fluctuations. Vegetation outside the cave varied significantly over time, including wet lowland forest, montane forest, savannah, and grassland. The new dates and the lithostratigraphy relate the Deep Skull to evidence of episodes of human activity that range in date from ca. 46,000 to ca. 34,000 years ago. Initial investigations of sediment scorching, pollen, palynomorphs, phytoliths, plant macrofossils, and starch grains recovered from existing exposures, and of vertebrates from the current and the earlier excavations, suggest that human foraging during these times was marked by habitat-tailored hunting technologies, the collection and processing of toxic plants for consumption, and, perhaps, the use of fire at some forest-edges. The Niah evidence demonstrates the sophisticated nature of the subsistence behavior developed by modern humans to exploit the tropical environments that they encountered in Southeast Asia, including rainforest.

The Cyrenaican Prehistory Project 2012: the sixth season of excavations in the Haua Fteah cave

The 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 rn of sediment cut through by the Deep Sounding. Evidence for human fréquentation 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 warmstage 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.

The Science of a Lost Medieval Graveyard: The Ballyhanna Research Project

he Science of Lost Medieval Gaelic Graveyard tells the story of the discovery in 2003 of a graveyard and the foundations of a small forgotten stone church at Ballyhanna, in Ballyshannon, Co. Donegal, as part of the N15 Bundoran–Ballyshannon Bypass archaeological works. This led to the excavation of one of the largest collections of medieval burials ever undertaken on this island. Over 1,200 individuals were excavated from the site at Ballyhanna during the winter of 2003–4, representing 1,000 years of burial through the entire Irish medieval period. The discovery led to the establishment of a cross-border research collaboration—the Ballyhanna Research Project—between Queen’s University Belfast and the Institute of Technology, Sligo, which has brought to life this lost Gaelic graveyard.

This book shows how cutting-edge scientific research may aid our understanding and interpretation of archaeology and reveal new insights into past societies. For example, the use of ancient DNA analysis represented the first biomolecular archaeological evaluation of a medieval population to date and provided evidence that cystic fibrosis was much less prevalent in the medieval period than today. The Science of Lost Medieval Gaelic Graveyard is about a community who lived in Gaelic Ireland, about their lifestyles, health and diet. It tells us of their deaths and of their burial traditions, and through examining all of these aspects, it reveals the ebb and flow of their lives.

The book is accompanied by a CD-ROM which includes supplementary information from the Ballyhanna Research Project and the original excavation and survey reports for all of the archaeological sites on the N15 Bundoran–Ballyshannon Bypass.

The Application of Digital Photogrammetric Techniques and Aerial Photography to the Preservation of Archaeological Detail. Case Study: The Copney Stone Circle Complex, Co. Tyrone, N. Ireland

The Copney Stone Circle Complex, Co. Tyrone, N. Ireland, is an important Bronze Age site forming part of the Mid-Ulster Stone Circle Complex. The Environment Service: Historic Monuments and Buildings (ESHMB) initiated a program of bog-clearance in August 1994 to excavate the stone circles. This work was completed by October 1994 and the excavated site was surveyed in August 1995. Almost immediately, the rate at which the stones forming the circles were breaking down was noted and a program of study initiated to make recommendations upon the conservation of this important site. Digital photogrammetric techniques were applied to aerial images of the stone circles and digital terrain models created from the images at a range of scales. These provide base data sets for comparison with identical surveys to be completed in successive years and will allow the rate of deterioration, and the areas most affected, of the circles to be determined. In addition, a 2D analysis of the stones provides an accurate analysis of the absolute 2D dimensions of the stones for rapid desktop computer analysis by researchers remote from the digital photogrammetric workstation used in the survey.

The products of this work are readily incorporated into web sites, educational packages and databases. The technique provides a rapid and user friendly method of presentation of a large body of information and measurements, and a reliable method of storage of the information from Copney should it become necessary to re-cover the site.

Precision dating of the Palaeolithic: A new radiocarbon chronology for the Abri Pataud (France), a key Aurignacian sequence

This paper presents a new series of AMS dates on ultrafiltered bone gelatin extracted from identified cutmarked or humanly-modified bones and teeth from the site of Abri Pataud, in the French Dordogne. The sequence of 32 new determinations provides a coherent and reliable chronology from the site's early Upper Palaeolithic levels 5-14, excavated by Hallam Movius. The results show that there were some problems with the previous series of dates, with many underestimating the real age. The new results, when calibrated and modelled using a Bayesian statistical method, allow detailed understanding of the pace of cultural changes within the Aurignacian I and II levels of the site, something not achievable before. In the future, the sequence of dates will allow wider comparison to similarly dated contexts elsewhere in Europe. High precision dating is only possible by using large suites of AMS dates from humanly-modified material within well understood archaeological sequences modelled using a Bayesian statistical method. © 2011.

Radiocarbon chronology for the Early Gravettian of northern Europe : new AMS determinations for Maisieres-Canal, Belgium

The authors explore the arrival of the earliest Gravettian in north-west Europe, using new high precision radiocarbon dates for bone excavated at Maisieres-Canal in Belgium to define a short-lit^ed occupation around 33 000 years ago. The tanged points in that assemblage have parallels in British sites, including Goat's Hole (Paviland). This is the site of the famous ochred burial of a young adult male, confiisingly known as the 'Red Lady', notv dated to around 34 000 BP. The new results demonstrate that this British 'rich burial' and the Gravettian with tanged points may bebng to two different occupation horizons separated by a cold spell.

Bauxite residue (Red mud) as a pulverised fuel ash substitute in the manufacture of lightweight aggregate

This study looked at the potential of bauxite residue or red mud to be used in the manufacture of lightweight aggregate in replacement of pulverised fuel ash (PFA), commonly used as a way of recycling problematic wastes. The percentage replacements of red mud with PFA were as follows: 25, 31, 38, 44 and 50%. These were blended in a mix with waste excavated clay and sewage sludge – all from the Chongqing municipality in China. Lightweight pellets were produced using a Trefoil rotary kiln and were sintered to 1200 °C. Results showed that 44 % bauxite residue replacement produced lightweight pellets with the highest compressive strength, highest density and largest water holding capacity. This would be expected in materials with a low level of silicates, which causes insufficient glass phase viscosity and therefore poor bloating during firing; producing an aggregate with a higher density but with open pores that allowed for larger water absorption. All ratios of red mud aggregates were significantly reduced in pH after firing to around pH 8, and this reduced the leachability of the aggregates to levels below those set by the European landfill directive (2003/33/EC).

Microtunelação. Aplicação a um caso de obra

Um túnel é uma obra subterrânea dimensionada com o objetivo de satisfazer diversas necessidades num mundo onde o planeamento urbano e a gestão de espaços ganha cada vez mais importância. A execução de este género de obras de engenharia pode ter várias finalidades, que podem ir desde a construção/reabilitação de redes de saneamento, abastecimento de água ou gás (túneis de pequeno diâmetro) até à construção/modernização de redes pedonais, rodoviárias ou ferroviárias, galerias mineiras, tuneis para barragens, etc. (túneis de grande diâmetro). As tuneladoras são uma das ferramentas de desmonte mais utilizadas na execução de obras subterrâneas. Existem no mercado vários tipos de máquinas tuneladoras, a sua escolha e dimensionamento depende de diversos fatores que devem ser cuidadosamente analisados, nomeadamente tipo de terreno a escavar, presença ou não de água na zona de escavação, dureza e/ou abrasividade das formações a atravessar, etc. Será feita uma abordagem aos princípios de funcionamento de este tipo de equipamentos, indicando o seu campo de aplicação dentro da respetiva tecnologia de escavação onde se inserem. Finalmente será desenvolvido o caso da empreitada: “Execução da Travessia do Rio Ave, da Estação Elevatória de Vila do Conde e dos Sistemas Elevatória da Aguçadoura e da Apúlia 4 - AR 44.0.08”, onde em alternativa ao desvio provisório do Rio Ave em Vila do Conde foi projetada a execução de duas travessias no diâmetro 1200 mm, uma delas escavadas maioritariamente em terreno aluvionar brando e a outra em terreno rochoso duro e abrasivo com recurso, em ambos casos, à utilização de máquina tuneladora. Através da avaliação do desempenho do equipamento escolhido para execução de este trabalho será estudada a eficiência da utilização deste tipo de equipamento. Com o objetivo de mostrar os custos associados à execução de obras de escavação subterrânea com recurso a utilização de máquinas tuneladoras, será feita uma análise económica e comparativa relativa aos dois casos de obra apresentados.

Facies, depositional environment, and palaeoecology of the Middle Triassic Cassina Beds (Meride Limestone, Monte San Giorgio, Switzerland).

The Ladinian Cassina beds belong to the fossiliferous levels of the world-famous Middle Triassic Monte San Giorgio Lagerstatte (UNESCO World Heritage List, Canton Ticino, Southern Alps). Although they are a rich archive for the depositional environment of an important thanatocoenosis, previous excavations focused on vertebrates and particularly on marine reptiles. In 2006, the Museo Cantonale di Storia Naturale (Lugano) started a new research project focusing for the first time on microfacies, micropalaeontological, palaeoecological and taphonomic analyses. So far, the upper third of the sequence has been excavated on a surface of around 40 m(2), and these new data complete those derived from new vertebrate finds (mainly fishes belonging to Saurichthys, Archaeosemionotus, Eosemionotus and Peltopleurus), allowing a better characterization of the basin. Background sedimentation on an anoxic to episodically suboxic seafloor resulted in a finely laminated succession of black shales and limestones, bearing a quasi-anaerobic biofacies, which is characterized by a monotypic benthic foraminiferal meiofauna and has been documented for the first time from the whole Monte San Giorgio sequence. Event deposition, testified by turbidites and volcaniclastic layers, is related to sediment input from basin margins and to distant volcanic eruptions, respectively. Fossil nekton points to an environment with only limited connection to the open sea. Terrestrial macroflora remains document the presence of emerged areas covered with vegetation and probably located relatively far away. Proliferation of benthic microbial mats is inferred on the basis of microfabrics, ecological considerations and taphonomic (both biostratinomic and diagenetic) features of the new vertebrate finds, whose excellent preservation is ascribed to sealing by biofilms. The occurrence of allochthonous elements allows an insight into the shallow-waters of the adjoining time-equivalent Salvatore platform. Finally, the available biostratigraphic data are critically reviewed.

Dr. Stuart D. Scott Papers, 1837-2010 (non-inclusive)

Dr. Stuart D. Scott has written extensively in the fields of prehistory and history. As an archaeologist, he has traveled to some of the most significant sites in the world, including Pompeii, Stonehenge, the Valley of the Kings, Egypt’s pyramids and the Taj Mahal. He spent nine months excavating with the Tikal Project in Guatemala before returning to the University of Arizona where he received a Ph.D. in 1963. He excavated in New Zealand as a Fulbright scholar in 1963-1964. In the fall of 1964, Dr. Scott started a long career in the Anthropology Department of the State University of New York. He taught graduate and undergraduate archaeology courses and continued his archaeological and historical research. In 1979, Scott established the Old Fort Niagara Archaeology in Progress Project at Old Fort Niagara in Youngstown, New York. For many years, he became involved with historical archaeology in western New York. It was during this work that he became interested in the Upper Canada Rebellion of 1837-1838 and its aftermath. Dr. Scott and his wife, Patricia Kay Scott, would use Christmas breaks, summer vacations, and sabbatical years to travel. They were repeatedly lured back to the South Pacific, conducting research in New Zealand, Australia and many of the Micronesian and Polynesian islands. To tell the whole story of the Rebellion and the prison exiles, they traveled extensively in Canada, the United States, England and Tasmania to collect archival research and to experience the scenes of this remarkable narrative. In 2004, Dr. Scott published To the Outskirts of Habitable Creation: Americans and Canadians Transported to Tasmania in the 1840s, which told the story of the men captured, tried, convicted, and exiled as a result of the Rebellion, also called the Patriot War. Other contributions include: • A collaboration with Dr. Charles Cazeau on the book Exploring the Unknown, Great Mysteries Reexamined published by Plenum Press in 1979 • The Patriot Game: New Yorkers and the Canadian Rebellion of 1837-1838, which appeared in New York History, Vol. 68, No.3. 1987 • A Frontier Spirit: The Life of James Gemmell published in Australiasian Canadian Studies, Vol. 25, No. 2 2007 • To the Outskirts of Habitable Creation which appeared in the Friends of the National Archives, Vol. 20, No. 1 2009 • Numerous academic journal publications • Service on conference panels • Various research papers and proposals Before retiring in 1997 and while still a resident of Buffalo, N.Y., Dr. Scott spent considerable time with Brock University President Emeritus James A. Gibson and History Professor Colin Duquemin. The three shared a love of Rebellion history. It was largely because of this connection that Brock University was chosen as the recipient of Dr. Scott’s research materials.

Faunal exploitation at the middle paleolithic site Kabazi II(Western Crimea)

Kabazi II est un site de plein air, situé sur la deuxième rangée des Monts de Crimée. Après sa découverte en 1986, les investigations archéologiques effectuées entre 1987 et le milieu des années 90 ont établi que Kabazi II avait auparavant servi de lieu de chasse et d’abattage pour les groupes néanderthaliens de la région. Les études archéozoologiques antérieures (Patou-Mathis 2003, 1999, 2005, 2006a, 2006b) ont déterminé que les stratégies de subsistance des Néanderthaliens du Kabazi II étaient très spécialisées et principalement axées sur la chasse des petits groupes de Equus hydruntinus mais aussi, à l’occasion, sur la chasse d’autres espèces. Ces comportements ont persisté malgré les changements climatiques et technologiques à travers l’histoire d’occupation du site. Cette étude présente l’analyse des assemblages fauniques encore inédits des niveaux II/1,II/2-1, II/2, II/3, II/4, II/5, II/7, II/8, II/9, II/13, II/13A de Kabazi II. Nos résultats sont en accord avec ceux obtenus parles d’études antérieures ; cependant, des différences par rapport à la fonction du site ont été constatées et un lien possible avec Kabazi V, un abri sur roche tout près de Kabazi II, a été établi. On croit que la persistance des activités de subsistance des Néanderthaliens de Kabazi II pendant presque 100 000 ans de présence est due à la polyvalence des ânes asiatiques tels que Equus hydruntinus, au contexte géographique et géologique de la région ainsi qu’aux caractéristiques du site elles-mêmes.

L'occupation des monticules architecturaux au site Las Mercedes du Costa Rica : une étude de la variabilité stylistique de la céramique

Le site archéologique de Las Mercedes est situé sur le versant atlantique du Costa Rica. Ce site monumental est considéré comme le haut lieu d'une société hiérarchisée ayant une organisation sociopolitique complexe. Las Mercedes semble avoir été un centre administratif et cérémoniel dont l'apogée se situe entre 1000 et 1500 ans de notre ère. Notre mémoire porte sur la documentation d'assemblages céramiques extraits de contextes archéologiques stratigraphiques provenant notamment de deux monticules architecturaux. Notre projet se veut une contribution à une meilleure connaissance de Las Mercedes, selon une perspective diachronique d'affiliation culturelle et de séquences d'occupation. Les datations radiométriques provenant de l'assise des monticules convergent aux alentours de l'an 1000 de notre ère. D'autre part, les assemblages céramiques correspondant aux styles culturels El Bosque (500 avant notre ère à 500 de notre ère), La Selva (500-1000) et La Cabana (1000-1500) représentant une séquence temporelle d'environ deux millénaires. La présente étude vise à comprendre ce phénomène à l'aide des données provenant de l'intervention archéologique conduite, en 2005, conjointement par le Museo Nacional du Costa Rica et l'Université de Montréal. Les assemblages sont décrits selon des attributs technologiques, morphologiques et stylistiques en vue d'en faire une étude comparative et interprétative. Les résultats de notre recherche suggèrent qu'indépendamment des contextes archéologiques, les assemblages ont un composition hétérogène formée des trois styles culturels. Par ailleurs, le modèle présente un certain caractère homogène. Ainsi, les assemblages se composent de façon récurrente de 12% de céramique El Bosque, 55 % La Selva et 33 % La Cabana. Une interprétation parcellaire peut être soutirée de ce mélange céramique. L'amalgame des styles culturels témoignent que Las Mercedes a connu une longue occupation, toutefois les résultats ne permettent pas de confirmer ou d'infirmer nos hypothèses de travail.

Contenu total en éléments traces de sols forestiers du Québec méridional

Les sols forestiers constituent un réservoir considérable d’éléments nutritifs disponibles pour soutenir la productivité forestière. Ces sols contiennent aussi une quantité, encore inconnue à ce jour, d’éléments traces biodisponibles provenant de sources anthropiques ou naturelles. Or, plusieurs de ces éléments recèlent un potentiel toxique pour les organismes vivants. Ainsi, la quantification de la concentration et du contenu total en éléments traces des sols forestiers s’avère nécessaire afin d’évaluer les impacts des perturbations sur la qualité des sols. Les objectifs de ce projet de recherche sont: 1) de mesurer le contenu total en éléments traces en phase solide (Ag, As, Ba, Cd, Ce, Co, Cr, Cu, Mn, Ni, Pb, Rb, Se, Sr, Tl, V, Y, Zn) des divers horizons de sols d’écosystèmes forestiers du Québec méridional; 2) d’établir des liens significatifs entre la fraction soluble dans l’eau des éléments traces et les propriétés des horizons de sols et; 3) d’évaluer le rôle de la proximité d’un centre urbain sur les contenus en éléments traces. Pour répondre à ces objectifs, quatre profils de sols situés dans la région de St-Hippolyte et deux situés dans la région de Montréal furent échantillonnés jusqu'à l'atteinte du matériel parental. Les résultats de ce projet de recherche ont révélé que le contenu total en éléments traces présents dans les profils de sols se retrouve en grande partie dans les fragments grossiers du sol. Il a été démontré que la teneur en carbone organique, les complexes organométalliques et les oxydes de fer et d’aluminium dictent la distribution en profil de la majorité des éléments traces étudiés. Finalement, il fut prouvé que la région de Montréal présente des niveaux de contamination en éléments traces (Ag, As, Ba, Cu, Mn, Pb, Rb, Se, Sr, Tl et Zn) supérieurs à ceux rencontrés dans les Laurentides.
