Nova Publicação para Cerâmica Calderon

 

Valentin Calderón figura como um dos pioneiros da arqueologia no Nordeste do Brasil. Membro do Programa Nacional de Pesquisas Arqueológicas entre as décadas de 1960 e 70, foi responsável pelos levantamentos sistemáticos nos sítios arqueológicos do estado da Bahia e identificou a tradição cerâmica Aratu. Calderón foi também o idealizador do Museu de Arqueologia e Etnologia da Universidade Federal da Bahia (MAE/UFBA), que hoje salvaguarda sua coleção arqueológica e seu arquivo pessoal. Em uma parceria realizada com pesquisadores do Center for Regional Heritage Research da Stephen F. Austin University, Texas, EUA, os artefatos cerâmicos da coleção Valentin Calderón foram digitalizados através do uso de tecnologias 3D. No total, foram escaneados 27 objetos cerâmicos, dentre vasilhames e urnas funerárias. A iniciativa ofereceu subsídios para pensar a digitalização como forma de preservação, principalmente no que se refere à conservação e restauração, documentação e comunicação do acervo. Os modelos 3D resultantes do processo de digitalização permitem uma análise detalhada dos artefatos e obtenção de dados sem a manipulação direta, contribuindo de forma relevante para a preservação dos acervos. Os dados e modelos serão, em breve, disponibilizados para a pesquisa e também utilizados na nova exposição de longa duração do MAE/UFBA.

3D Ceramics from the Arizona State Museum at the University of Arizona

Any time that I get to work alongside Dr. Suzanne Eckert is always a treat; so when I received an invitation to visit the Arizona State Museum at the University of Arizona to scan some ceramics for an upcoming pilot project with her, we made it happen. The vessels in question have a beveled rim/lip, and we will be looking into various ways of using the 3D data to expand upon current dialogues regarding the extent of this practice. And yes folks, those gloves are really purple.

In addition to the ceramics, I was also able to scan a selection of Clovis points from the Murray Springs and Naco sites. All of the scans will be made available in an open access format soon.

New publications in the Journal of Texas Archeology and History

The first two peer-reviewed data papers have just been published in the Journal of Texas Archeology and History, detailing the hardware, software and methods used to generate these two important datasets. This helps to keep the data collection process transparent, and ensures that we are following best practices in terms of data collection, processing and digital curation. These data papers are open access; simply click on the image of the cover page to be transferred to each.

Many thanks to the Caddo Nation of Oklahoma, Texas Archeological Research Laboratory and the Texas Parks and Wildlife Department for the requisite permissions and access needed to generate the scans.
