2012 spring meeting of the Association for Environmental Archaeology

The 2012 spring meeting of the Association for Environmental Archaeology will take place on 21st April 2012 at Plymouth University. It will be a student focused meeting, although attendance and presentation from practitioners from the commercial sector and more established academics is encouraged. Oral and poster presentations on any aspect of Environmental Archaeology are welcomed and it is hoped that the full range of sub-disciplines of environmental archaeology will be represented. A limited number of travel bursaries will be available to student presenters. The deadline for abstract submission (250 words max) is 1^st February. Posters advertising the conference can be downloaded from the AEA website at:

http://www.envarch.net/events/index.html#spring.

We would be very grateful if you could display these in your institutions. Registration forms will be made available from the same website shortly.For further information or to submit an abstract please contact Marta Perez (marta.perez@plymouth.ac.uk).

Territórios de Fronteira

Vai ter lugar às 18 horas do próximo dia 6 de Dezembro o V ciclo de conferências Territórios de Fronteira no Museu Nacional de Arqueologia. Além desta, o evento é também co-organizado por outras duas organizações: Grupo de Estudos em Evolução Humana e Núcleo de Arqueologia da Universidade do Algarve.

Fitolitos - base de dados

Citando:

The Research Group for Palaeocological and Geoarchaeological Studies (GEPEG) of the University of Barcelona was created in 2005 with the purpose of, among others, conducting phytolith and mineralogical analyses of archaeological sediments to better understand the exploitation of plant resources by past populations, as well as to conduct climatic and vegetation reconstructions, taking into account the different postdepositional processes that can affect the archaeological material.

Along these years of research, GEPEG has created microphotographs of phytoliths that might serve as a reference catalog to identify the phytoliths from the different areas of study.

We are pleased to present the GEPEG Phytolith-Core Reference Collection. This is a new phytolith catalog which is available at http://gepeg.org/enter_PCORE.html

The catalog is based on phytolith images collected from three different sources:
- Modern reference plant material from the study areas.
- Modern soils collected from the same areas as modern plants or from areas that were previously described in terms of vegetation.
- Archaeological material.

The catalog not only provides microphotographs of phytoliths but also related information such as provenience of the sample, date of collection, in the case of modern soil assemblages, description of the vegetation from where the samples were collected, etc.

Single-grain OSL dating at La Grotte des Contrebandiers

Jacobs Z., Meyer M. C., Roberts R. G., Aldeias V., Dibble H.,El Hajraoui M. A. (2011). Single-grain OSL dating at La Grotte des Contrebandiers (‘Smugglers’ Cave’), Morocco: improved age constraints for the Middle Paleolithic levels. Journal of Archaeological Science, 38 (12): 3631-3643.

Optically stimulated luminescence (OSL) measurements of individual quartz grains are reported for Middle Paleolithic (MP) or Middle Stone Age (MSA) deposits in La Grotte des Contrebandiers, Morocco. Single-grain measurements enable rejection of grains that may lead to under- or over-estimation of age due to malign luminescence properties or remobilisation of grains after burial. We identified the former using a range of experimental procedures and objective rejection criteria. Three post-depositional factors influenced the distribution pattern of equivalent dose (D_e) values for the remaining single grains: the disintegration of roof spall liberating unbleached, older grains into otherwise well-bleached sediments; the intrusion of a small number of younger grains from the overlying Upper Paleolithic deposits; and small-scale differences in the beta dose received by individual grains. Roof spall contamination was a significant problem, so we characterised the OSL signals and obtained D_e values for the calcareous sandstone in which the cave is formed, which allowed bedrock-derived grains in the MP/MSA deposits to be identified and rejected prior to age determination. We collected 31 samples from the MP/MSA deposits, and were able to calculate ages for 30 of them. These ages suggest that MP/MSA occupation of Contrebandiers was restricted to the interval between about 120 and 90 ka ago (Marine Isotope Stages 5d to 5b). Weighted mean OSL ages were obtained for samples associated with archaeologically sterile deposits at the base of the excavations (126 ± 9 ka), followed by two phases of the Moroccan Mousterian (122 ± 5 and 115 ± 3 ka), interspersed with archaeologically sterile deposits (112 ± 4 ka). The base and top of the Aterian were dated to 107 ± 4 and 96 ± 4 ka, respectively. Based on the grand weighted mean ages of 116 ± 3 and 103 ± 3 ka for the Moroccan Mousterian and Aterian at Contrebandiers, we suggest that these two industries may be separated by an occupation hiatus of up to 13 ± 3 ka at this site. Our single-grain OSL chronology confirms previous age estimates obtained for Contrebandiers and other sites in the vicinity, but are generally more precise and stratigraphically more coherent, due to the inherent advantages of measuring individual quartz grains and rejecting contaminant and other unsuitable grains before age determination.

the introduction of the Egyptian mongoose (Herpestes ichneumon) [sacarrabos] in Iberia

Detry C., Bicho N., Fernandes H.,Fernandes C. (2011). The Emirate of Córdoba (756–929 AD) and the introduction of the Egyptian mongoose (Herpestes ichneumon) in Iberia: the remains from Muge, Portugal. Journal of Archaeological Science, 38 (12): 3518-3523.

We describe new finds of Herpestes ichneumon (Egyptian mongoose) from an archaeological context in Portugal, directly 14C dated to c. 800 AD. This is at least two centuries older than a previously reported find of this species from Andalusia (southern Spain; Riquelme-Cantal et al., 2008). Our finding provides further support to the hypothesis that the Muslims introduced this animal to the Iberian Peninsula. In particular, we suggest that Berber settlers might have brought it some time during the Umayyad conquest of Iberia or with the establishment of the Emirate of Córdoba.

Roman villa of Casal de Freiria

Rua H.,Alvito P. (2011). Living the past: 3D models, virtual reality and game engines as tools for supporting archaeology and the reconstruction of cultural heritage – the case-study of the Roman villa of Casal de Freiria. Journal of Archaeological Science, 38 (12): 3296-3308.

“Learn about the past to better understand the present and predict the future”. Although used abundantly to justify our interest in ancient societies, this statement lacks practical meaning due to the high degree of uncertainty which cloaks archaeological studies and theories, and the fact that there is no real way to prove or validate them. That is why it is so important to approach this study from a multidisciplinary point of view, providing several inputs which complement each other and so maximize the amount of factual information drawn from the analysis. Even then, the study will never be truly complete because there will always be a missing document, a small trace of an object (Verhagen, 2008), that still needs to be analysed. This paper aims to be a useful contribution to historical research, specifically to the study of architectural history. Its purpose is to create a series of methods and tools for testing and analysing theories and hypotheses for historical scenarios (Vasáros, 2008) through the use of 3D modelling tools and Virtual Reality (VR) engines. The project was developed in two stages: The first was the creation of several three-dimensional (3D) models, each representing a different theory or hypothesis. The models were based on accurate Computer Assisted Design (CAD) (Autodesk® AutoCAD) models for the reconstruction of the buildings, and Geographic Information Systems (GIS) (ESRI®) for the recreation of the terrain, thereby creating a realistic representation of what exists now, and a close approximation to what may have once existed. In the second stage, a simplified version of the models was imported into a Virtual Reality (VR) game engine (Bethesda Softworks®) to create the ambience of the villa at the time, allowing full exploration of the space. It also includes fauna and flora, as well as Artificial Intelligence (AI)-driven avatars, as can be seen in the Video 1 provided in the electronic version of this manuscript.
