Considerations For Post-Processing Parameters In Mixed-Method 3d Analyses: A Mesolithic Mandibular Case Study, Robert Z. Selden Jr., Lauren N. Butaric, Kersten Bergstrom, Dennis Van Gerven Jan 2021

Considerations For Post-Processing Parameters In Mixed-Method 3d Analyses: A Mesolithic Mandibular Case Study, Robert Z. Selden Jr., Lauren N. Butaric, Kersten Bergstrom, Dennis Van Gerven

CRHR: Archaeology

The production of three-dimensional (3D) digital meshes of surface and computed tomographic (CT) data has become widespread in morphometric analyses of anthropological and archaeological data. Given that processing methods are not standardized, this leaves questions regarding the comparability of processed and digitally curated 3D datasets. The goal of this study was to identify those processing parameters that result in the most consistent fit between CT-derived meshes and a 3D surface model of the same human mandible. Eight meshes, each using unique thresholding and smoothing parameters, were compared to assess whole-object deviations, deviations along curves, and deviations between specific anatomical features …


Ceramic Morphological Organization: Quiddity Of Shape For Hickory Engraved Bottles, Robert Z. Selden Jr. Jan 2018

Ceramic Morphological Organization: Quiddity Of Shape For Hickory Engraved Bottles, Robert Z. Selden Jr.

CRHR: Archaeology

This study expands upon a previous analysis of the Clarence H. Webb collection, which resulted in the identification of two Caddo bottle shapes used in the manufacture of Hickory Engraved (HE) bottles. The current sample of Caddo bottles adduces three-dimensional meshes from the HE specimens in the Webb collection, as well as 14 new meshes from six sites and one collection; all of which fall under the purview of the Native American Graves Protection and Repatriation Act (NAGPRA). Results confirm that HE bottle shape differs significantly by site in some cases, that the two discrete shapes identified in the previous …


A Preliminary Study Of Smithport Plain Bottle Morphology In The Southern Caddo Area, Robert Z. Selden Jr. Jan 2018

A Preliminary Study Of Smithport Plain Bottle Morphology In The Southern Caddo Area, Robert Z. Selden Jr.

CRHR: Archaeology

This study expands upon a previous analysis of the Clarence H. Webb collection, which resulted in the identification of two discrete shapes used in the manufacture of the base and body of Smithport Plain bottles. The sample includes the Smithport Plain bottles from the Webb collection, and four new bottles: two previously repatriated specimens in the Pohler Collection, and two from the Mitchell site (41BW4) to test whether those specimens align morphologically with the Belcher Mound or Smithport Landing specimens. Results indicate significant allometry and a significant difference in Smithport Plain body and base shapes for bottles produced at the …


Geometric Morphometrics Of Gary Dart Points From The Davy Crockett National Forest, David A. Foxe, Robert Z. Selden Jr., Juanita D. Garcia Jan 2018

Geometric Morphometrics Of Gary Dart Points From The Davy Crockett National Forest, David A. Foxe, Robert Z. Selden Jr., Juanita D. Garcia

CRHR: Archaeology

Three-dimensional scans of Gary dart points recovered from the Davy Crockett National Forest are employed in tests of basal morphology by site, size (allometry), and asymmetry. Variability in basal morphology for Gary points from sites on the Davy Crockett National Forest is presented and compared to specimens from the published type books. The hypothesis that Gary basal morphology differs between sites containing Woodland-era sand temped ceramics and those where no sand tempered ceramics were recovered is then tested and the results discussed.
