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 …
First Test Of Habitat Suitability Models For The Davy Crockett National Forest, Robert Z. Selden Jr., David A. Foxe, Juanita D. Garcia
First Test Of Habitat Suitability Models For The Davy Crockett National Forest, Robert Z. Selden Jr., David A. Foxe, Juanita D. Garcia
CRHR: Archaeology
The test for this suite of models was conducted as a double-blind survey since neither the United States Forest Service personnel (excepting Garcia) nor the participants were provided with any information regarding the model in advance of testing. Input from the model was shared with the crew the day after each location was tested. Enlistment of the double-blind survey method aids in reducing survey bias. Collection of data for this project begins with the stratified random sample. The sample consists of random locations throughout compartments of the Davy Crockett National Forest. Those locations not visited in the first test of …

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 …

Lithic Morphological Organization: Gahagan Bifaces From Texas And Louisiana, Robert Z. Selden Jr., John E. Dockall, Harry J. Shafer
CRHR: Archaeology
This study is focused upon an analysis of Gahagan biface morphology and enlists the three largest samples of these bifaces, to include that of the type site (Gahagan Mound) as well as the Mounds Plantation and George C. Davis sites. Results indicate a significant difference in Gahagan biface morphology at the Mounds Plantation site when compared with Gahagan bifaces from the Gahagan Mound and George C. Davis sites. A test of morphological integration indicates that the bifaces are significantly integrated, meaning that those traits used to characterize their shape (blade and base) vary in a coordinated manner. Tests for allometry …

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
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.
Addressing Survey Bias: Maxent Models And Public Archaeology At The Davy Crockett National Forest, Juanita D. Garcia, Robert Z. Selden Jr., David A. Foxe
Addressing Survey Bias: Maxent Models And Public Archaeology At The Davy Crockett National Forest, Juanita D. Garcia, Robert Z. Selden Jr., David A. Foxe
CRHR: Archaeology
Over the past 30+ years, compliance-based archaeological projects conducted on the Davy Crockett National Forest have yielded an impressive contribution to the archaeological record. However, those efforts were limited to specific survey areas based upon specific needs. To begin to address survey bias and the impact that it can have on site probability models, a stratified random sample of 50 locations was generated for the forest. In early 2018, a public archaeology (Passport-in-Time) project was used to engage interested volunteers who assisted in testing these sample locations. These results, as well as other new data, were added to the maxent …
Cave Winch: When A Looter's Tool Becomes An Artifact, Robert Z. Selden Jr., J Javi Vasquez
Cave Winch: When A Looter's Tool Becomes An Artifact, Robert Z. Selden Jr., J Javi Vasquez
CRHR: Archaeology
As an archaeologist, it is often difficult to empathize with looters and collectors, but we would like to ask that you put aside any pre-conceived notions of judgment as we consider the question: when does a looter’s tool become an artifact? For the two of us, this particular dialogue began in the summer of 2013 on an excavation at Sierra Diablo Cave in western Texas. In that cave was a winch that we assume was constructed on or near the site as a tool for excavating deposits near the rear of the cave.

Asymmetry Of Caddo Ceramics From The Washington Square Mound Site: An Exploratory Analysis, Robert Z. Selden Jr.
Asymmetry Of Caddo Ceramics From The Washington Square Mound Site: An Exploratory Analysis, Robert Z. Selden Jr.
CRHR: Archaeology
While pursuing a study of 3D geometric morphometrics for ceramic burial vessels that often articulate with the Native American Graves Protection and Repatriation Act (NAGPRA) from the ancestral Caddo region, there have been no shortage of potentially meaningful observations, one of which--rotational asymmetry in coil-built vessels--is discussed here. Using Geomagic Design X (reverse-engineering software) and Geomagic Control X (inspection software), metrics associated with rotational asymmetry were generated then analyzed. Results indicate variable asymmetry among the different vessel shapes (i.e., bottles, jars, etc.), which may augment and strengthen studies and discussion of vessel form. Future directions include the incorporation of directional …

The Index Of Texas Archaeology: Open Access Gray Literature From The Lone Star State, Robert Z. Selden Jr., C. Britt Bousman
CRHR: Archaeology
Cultural resources management (CRM) reports represent a rapidly growing proportion of our knowledge associated with archaeological undertakings in the United States. Historically, these reports were printed in limited numbers and distributed to a few libraries and individuals, and few were distributed beyond the political boundaries of any given state. Libraries on the distribution list are reticent to allow patrons to check out these reports due to the fact that they have—and will only ever have—a single copy. Late in 2009, the Texas Historical Commission (THC) permitting guidelines for CRM reports were updated, requiring CRM contractors to submit a digital copy …

Using Photogrammetry To Document, Analyze, And Reverse-Engineer Grave Markers, Robert Z. Selden Jr.
CRHR: Archaeology
There are a wide range of applications for three-dimensional (3D) data in archaeology, and a diverse array of methods for collecting and analyzing those data. In this article, free 3D photogrammetry software (Autodesk 123D Catch) is used to document a series of grave markers. The data are subsequently exported to Geomagic Design X to demonstrate and briefly discuss the various potential analyses that might be used to illustrate the effects of preservation treatments and marker degradation through time. Further, one marker is reverse-engineered, illustrating the capacity of 3D modeling to expedite the process of design, should elements warrant replacement. Additional …
Linking Instrumental Neutron Activation Analysis (Inaa) With Geology In The Ancestral Caddo Region, Robert Z. Selden Jr.
Linking Instrumental Neutron Activation Analysis (Inaa) With Geology In The Ancestral Caddo Region, Robert Z. Selden Jr.
CRHR: Archaeology
This poster illustrates the success of a novel method of INAA that was employed to reveal geochemical signatures in Caddo ceramic vessel sherds that correlate with local surficial geology. The geochemical data from the sherd assemblage were used within an exploration of potential ceramic provenance, which was successful at demarcating sherds from ceramic vessels made from clays in either the Claiborne or Wilcox Groups. Further geochemical segregation was also apparent between the Recklaw Formation in the Claiborne Group, and the Weches Formation in the Wilcox Group. These results point to a high degree of geochemical variability within the East Texas …

Instrumental Neutron Activation Analysis (Inaa) Of Shell-Tempered Ceramics In The Ancestral Caddo Region: Rethinking Methods, Robert Z. Selden Jr., Timothy K. Perttula
CRHR: Archaeology
The geochemical analysis of shell-tempered ceramics in the ancestral Caddo region has been a matter of confusion since the mid-1990s. While Caddo archaeologists have long perceived most or all of the shell-tempered ceramics in East Texas to have originated from two different areas within the Red River basin, the geochemical data and interpretations remain inconsistent with that idea. This poster takes another look at this dataset, and considers an approach that was initially put forth by MURR, and then seemingly abandoned. Using only the geochemical data from shell-tempered sherds, we take a closer look at the contributions of calcium (Ca), …

Toward A Morphometric Phylogeny Of Caddo Ceramics: A Test Of 3d Geometric Morphometrics, Robert Z. Selden Jr., Timothy K. Perttula, Michael J. O'Brien
CRHR: Archaeology
In this poster we use 3D geometric morphometrics as an exploratory tool for examining diversity in vessel form (or shape) among 27 whole or reconstructed Caddo vessels from the Vanderpool site in Smith County, Texas. Forty-one landmarks from each vessel were exported to version 2.5 of Morphologika for generalized Procrustes analysis and principal components analysis and were then exported to R for cluster analysis (depending on sample size). Despite the small sample size, results indicate that 3D geometric morphometric analysis is an avenue of ceramic research where substantive analytical gains can be realized.

At The Confluence Of Gis And Geochemistry: Identifying Geochemical Correlates Of Ripley Engraved Caddo Ceramics, Robert Z. Selden Jr., Timothy K. Perttula
CRHR: Archaeology
In this poster, we discuss a new approach to the identification and definition of spatial trends in archeologically-recovered ceramics associated with geochemical results produced using instrumental neutron activation analysis (INAA). Using all of the Ripley Engraved INAA samples, we posit that clays in the Claiborne and Wilcox Groups can be successfully demarcated by sodium (Na), cerium (Ce), and zinc (Zn). Using a subset of those data from the Big Cypress Creek basin, we find that ceramics manufactured in three different Caddo political communities can be successfully demarcated based upon differential concentrations of arsenic (As), iron (Fe), and vanadium (V) found …

CRHR: Archaeology
Three-dimensional (3D) digital scanning of archaeological materials is typically used as a tool for artifact documentation. With the permission of the Caddo Nation of Oklahoma, 3D documentation of Caddo funerary vessels from the Vanderpool site (41SM77) was conducted with the initial goal of ensuring that these data would be publicly available for future research long after the vessels were repatriated. A digital infrastructure was created to archive and disseminate the resultant 3D datasets, ensuring that they would be accessible by both researchers and the general public (CRHR 2014a). However, 3D imagery can be used for much more than documentation. To …

As the costs associated with the collection of 3D data continue to plummet, there is little doubt that the number of available archaeology-related 3D datasets will increase dramatically in the coming decade. While our analytical procedures continue to evolve as new applications are contemplated, analyses of 3D data are increasing in frequency within the archaeological literature. In this article, we seek to provide a brief overview of a few examples from our own research and explore some possibilities that may add value to existing collections. In the following pages, we discuss some of the ways that 3D data have been …

This poster provides a short overview of what we have learned from the East Texas Radiocarbon Database since it became available on the Council of Texas Archeologists’ website in 2011. These successes are numerous and include the advancement of novel methodological approaches; an improvement in our comprehension of the temporal nuances within the East Texas Archaic; the division of the East Texas Woodland period into Early, Middle and Late; the refinement of Caddo temporal chronology – particularly from a geographic perspective -- and it has provided one line of evidence to use to argue for the fluorescence of corn-based agriculture …

Ceramic Petrofacies: Modeling The Angelina River Basin In East Texas, Robert Z. Selden Jr.
CRHR: Archaeology
Ceramic provenance studies remain the basis of worldwide archaeological research concerned with reconstructing exchange networks, tracing migrations, and informing upon ceramic economy. Unfortunately, Texas archaeologists have been plagued with an inability to trace ceramic production sources to the same extent as researchers within other regions. Ceramic petrofacies models have been employed successfully in archaeological contexts at the San Pedro Valley, Tonto basin, Tucson basin, Agua Fria, and Gila and Phoenix basins in Arizona, but have not yet been employed east of Arizona. Data resulting from the construction of an actualistic petrofacies model in the prehistoric coastal environment of East Texas …
