Advances in Documentation, Digital Curation, Virtual Exhibition, and a Test of 3D Geometric Morphometrics

Abstract

AbstractThree-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 illustrate this, these data were utilized in a 3D morphometric analysis of the intact and reconstructed vessels to explore the range of variation that occurs in ceramic vessel shape and its potential contribution to the local ceramic taxonomy. Results of the 3D morphometric analysis demonstrate the potential for substantive analytical gains in discussions of temporal resolution and ceramic technological organization in the ancestral Caddo region.
