I will be teaching a section of the National Center for Preservation Technology and Training’s Advanced 3D Imaging and Morphometrics for Archaeologists workshop from October 15 – 18, 2018 in the Conservation Laboratory at the Arizona State Museum, on the campus of the University of Arizona.
Other instructors include Bernard K. Means, Loren Davis, and Michael Shott who will be discussing public archaeology and outreach, 3D projectile point analysis, and theory and methods, respectively.
The objective of this workshop is to share and discuss the latest uses of 3D imaging of archaeological artifacts in order to improve the utility and precision of analyses that employ 3D data to assess morphological variation. Additional discussions will cover topics related to digital curation and public archaeology, where the utility of 3D scans reach beyond traditional analyses. To accomplish this, we are bringing together selected experts to one location to share their expertise. This four-day event will include lectures, a hands-on practicum, data analysis demonstrations, and discussions of best practices and data curation.

The preprint of my forthcoming BTAS article that explores morphological variation for a sample of Smithport Plain Caddo bottles is now available for download on SocArXiv. The follow-up to this piece integrates Caddo bottles from the Bison B site in northwest Louisiana curated at Southern Methodist University. This analysis is an iterative extension of my ongoing work with Caddo ceramic morphology, to which new collections are regularly added. Each iterative improvement includes an analysis of the recently scanned ceramics, then presents the results of a subsequent analysis of the aggregated sample.
Many thanks to the Caddo Nation of Oklahoma, the Williamson Museum at Northwestern State University, the Louisiana State Exhibit Museum, the Texas Archeological Research Laboratory, and the Louisiana State University (LSU) Museum of Natural Science for the requisite permissions and access needed to generate the 3D scans of the Caddo bottles used in this analysis. Development of the analytical workflow and production of 3D scans from the Clarence H. Webb collection was funded by a grant (P14AP00138) from the National Center for Preservation Technology and Training. Production of 3D scans for repatriated Caddo bottles from the Crenshaw Mound and the Pohler Collection was funded by a grant from the Caddo Nation of Oklahoma.
Between February 8-11, 2016, selected artifacts from the Blackwater Draw National Historic Landmark (LA3324) were scanned in advance of a grant proposal to digitally aggregate the Clovis-era artifacts from the Clovis type site. These data were collected using a NextEngineHD running ScanStudioHD Pro, and post-processed in Geomagic Design X 2016.0.1. All data associated with this project are publicly available (open access) and accessible in Zenodo under a Creative Commons Attribution license, where they can be downloaded for use in additional projects and learning activities. These data have the capacity to augment a variety of research designs spanning the digital humanities, applications of geometric morphometrics, and many others. Additionally, these scans will augment a wide range of comparative research topics throughout the Americas and beyond. Reuse potential for these data is significant.
Unprocessed 3D data are included on the landing page, and links to the processed files are included in the data paper. Download the data paper here:: 3D Scan Data for Selected Artifacts from Blackwater Draw National Historic Landmark
The National Forests and Grasslands in Texas and the Center for Regional Heritage Research would like to invite you to participate in a large public archaeology/outreach opportunity from February 18 – March 3, 2018 (two one-week sessions) to test and evaluate an archaeological site potential model for the Davy Crockett National Forest (http://www.passportintime.com/site-testing-on-the-davy-crockett-2018.html). This is a national call for volunteers, and is limited to 40 participants; however, we wanted to open the opportunity to locally-interested colleagues and students in advance of the formal announcement (no prior experience required). Registration is required by January 1, 2018 for all participants through the USFS Passport in Time website. Register by visiting the link above and filling out the short application using the Apply Now tab immediately below the image of the dart points.

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.
