Advanced 3D Imaging and Morphometrics for Archaeologists

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.

Geometric Morphometrics of Caddo bottles in the Clarence H. Webb Collection

Analyses of ceramic vessel shape are neither new or novel; however, the relatively recent adoption of geometric morphometric (GM) methods by archaeologists provides a preview of the contribution of GM to the systematic and rigorous study of morphology as applied to material culture. This study is focused upon an analysis of Caddo bottle shapes for Belcher Engraved, Hickory Fine Engraved, Keno Trailed, Smithport Plain, and Taylor Engraved vessels from the Allen Plantation, Belcher Mound, Gahagan Mound, and Smithport Landing sites in the Clarence H. Webb collections from northwest Louisiana. Results indicate some significant relationships between bottle shape and size (allometry), bottle shape and type, and bottle shape and site. A test of morphological integration indicates that the bottles are significantly integrated, meaning that those discrete traits used to characterise their shape (rim, neck, body, and base) vary in a coordinated manner, highlighting significant integration between suites of attributes. The Smithport Plain and Hickory (Fine) Engraved bottles found at the Belcher Mound, Smithport Landing, and Gahagan Mound sites also provide evidence for two discrete (north–south) base and body shapes.

Preprint of New BTAS Article Available on SocArXiv

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.

3D Scan Data for Selected Artifacts from Blackwater Draw National Historic Landmark

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
