Item A Lithic-Behavioral Investigation of Cultural Transmission Across the Middle to Upper Paleolithic Transition in Western Europe(2019-12) Porter, SamanthaNeanderthals are one of our closest evolutionary relatives. Molecular anthropology has shown that our species intermixed genetically, but the extent to which we interacted socially and exchanged technological information is still hotly debated, especially in the period approximately 40,000 years ago in Western Europe just prior to the Neanderthals’ extinction. This dissertation addresses elements of this question through a mixture of methodologies. This work is presented in the form of three papers. Paper 1 presents an inexpensive photography rig designed to create 3D artifact models using photogrammetry, also known as structure from motion. The second paper uses 3D models of cores generated with the system described in Paper 1 to compare Châtelperronian and Protoaurignacian lithic technology, which are associated with Neanderthals and anatomically modern humans respectively. The final paper presents an attribute-based analysis of artifacts from five assemblages from four sites linked to three technocomplexes spanning the so-called Middle to Upper Paleolithic transition. This analysis applies the middle range theory of the Behavioral Approach to Cultural Transmission to both test the hypothesis that there was cultural transmission between Neanderthal and anatomically modern human groups and infer the degree of social intimacy that is most likely to have existed between them.Item Three Dimensional Models and Two Dimensional Cross Sections of Châtelperronian and Protoaurignacian Lithic Cores from the Sites of Les Cottés and Roc de Combe(2018-05-29) Porter, Samantha T; Roussel, Morgan; Soressi, Marie; stporter@umn.edu; Porter, Samantha TThese data were generated as part of a study investigating the use of quantitative methods on three dimensional models of lithic artifacts. The majority of the data set is comprised of 3D scans of Châtelperronian and Protoaurignacian cores from the site of Les Cottés (France), which were generated using photogrammetry. Although cores from the site of Roc de Combe were also scanned for the associated study, we are not able to make them available here due to rights restrictions. The second part of the data set includes two dimensional representations of cross sections, which were from the 3D artifact models. These were used in two analyses, which are described in the associated publication in JCAA (see citation below).
