A Batalha do Vimeiro numa Perspetiva Arqueológica

Na presente dissertação apresentam-se os resultados dos trabalhos de arqueologia efetuados na colina do Vimeiro durante o ano de 2014, tendo em vista a análise de parte do campo de Batalha do Vimeiro. O estudo do espólio recolhido no que diz respeito à sua tipologia e localização espacial tem como objetivos finais compreender e identificar os vários momentos do combate da Colina do Vimeiro. Os dados recolhidos arqueologicamente serão em última análise uma visão aproximada da veracidade dos acontecimentos.

From Midden to Sieve: The Impact of Differential Recovery and Quantification Techniques on Interpretations of Shellfish Remains in Australian Coastal Archaeology

Experimental mechanical sieving methods are applied to samples of shellfish remains from three sites in southeast Queensland, Seven Mile Creek Mound, Sandstone Point and One-Tree, to test the efficacy of various recovery and quantification procedures commonly applied to shellfish assemblages in Australia. There has been considerable debate regarding the most appropriate sieve sizes and quantification methods that should be applied in the recovery of vertebrate faunal remains. Few studies, however, have addressed the impact of recovery and quantification methods on the interpretation of invertebrates, specifically shellfish remains. In this study, five shellfish taxa representing four bivalves (Anadara trapezia, Trichomya hirsutus, Saccostrea glomerata, Donax deltoides) and one gastropod (Pyrazus ebeninus) common in eastern Australian midden assemblages are sieved through 10mm, 6.3mm and 3.15mm mesh. Results are quantified using MNI, NISP and weight. Analyses indicate that different structural properties and pre- and postdepositional factors affect recovery rates. Fragile taxa (T. hirsutus) or those with foliated structure (S. glomerata) tend to be overrepresented by NISP measures in smaller sieve fractions, while more robust taxa (A. trapezia and P. ebeninus) tend to be overrepresented by weight measures. Results demonstrate that for all quantification methods tested a 3mm sieve should be used on all sites to allow for regional comparability and to effectively collect all available information about the shellfish remains.

Molecular archaeology

Advances in technologies such as mass spectrometry and capillary electrophoresis have encouraged the study of ancient lipids and other ancient biomolecules. Now, microarray technology looks set to revolutionise the study of ancient DNA, perhaps with as much impact as that of PCR.

The archaeology of the Peel Island Lazaret: Part 1: Survey

An archaeological survey on Peel Island in Moreton Bay, southeast Queensland, was conducted to assist the conservation planning for the Peel Island Lazaret (PIL), one of a number of institutions housed on the island during the nineteenth and twentieth centuries. The survey revealed a patteming of artefacts across the island as well as landscape modification related to its Aboriginal and European institutional uses.
