Title of Dataset: Three Dimensional Models and Two Dimensional Cross Sections of Châtelperronian and Protoaurignacian Lithic Cores from the sites of Les Cottés and Roc de Combe 02. Author Information: Name: Samantha Thi Porter Institution: University of Minnesota, Twin Cities Email:stporter@umn.edu Name: Morgan Roussel Institution: Leiden University Email:m.b.roussel@arch.leidenuniv.nl Name: Marie Soressi Institution: University of Minnesota Email:m.a.soressi@arch.leidenuniv.nl 03. Nature of the data: This dataset is derived from digital photographs collected between June 2014 and November 2016. It was processed into 3D models by Samantha Thi Porter with assistance from Dana Winkler at the University of Minnesota using the software Agisoft PhotoScan. Models were aligned and rotated about the origin using the software Geomagic Design X. Details about image acquisition, data processing, and artifact measurements can be found in 2_Porter_et_al_2019_JCAA_artifact_data.CSV and the associated paper, which is currently in peer review. 04.

SITE Archaeological site where the artifact was found. INDUSTRY Associated archaeological industry (Châtelperronian or Protoaurignacian). LEVEL Archaeological layer in which the artifact was found. All artifacts from Roc de Combe originate from Couche 8. Level information for artifacts from Les Cottes was provided by Soressi and Roussel. CAMERA The digital camera used to capture the photographs used to create the 3D models. SCALE What type of scale was used underneath the artifact during photography; see Porter_et_al_2019_JCAA_scales.PDF for examples. COATING Was the artifact coated with a powder to increase 3D model quality, and if so with what (developer, chaulk, or none). RETEXTURED If the artifact was coated, was the model retextured using a second set of digital photographs taken without coating, some textures edited in Adobe Photoshop to makes texture seams less visible. USED_IN_STUDY Was the artifact included in the final sample for the associated pending publication (Yes or No). Artifacts were only included if they had visible scars corresponding to at least two successful blade removals (scars were at least twice as long as they were wide, and did not end in step or hinge fractures). MODEL_AVAILABLE Is the model available for download as part of this data set (Yes or No). CROSS_SECTION_AVAILABLE Are cross sections derived from 3D models available for download as part of this data set (Yes or No). CORE_VOLUME Volume of the artifact in cubic centimeters. Empty fields reflect objects being excluded from the study sample. INTER_AXIS_ANGLE Angle in degrees between the axis of symmetry and axis of reduction (see associated pending publication for additional explanation). Empty fields reflect objects being excluded from the study sample. PLT_TO_DEB_ANGLE Angle in degrees between the platform and debitage surface (see associated pending publication for additional explanation, "Null" means angle could not be measured on pieces included in the study sample. Empty fields reflect objects being excluded from the study sample. PORTER_ET_AL_2016 Was a model of the artifact previously made available as part of part of Porter et al. 2016 (Yes or No). COMMENTS Additional MISC contextual information --------------------- EXPLANATION OF 3D FILES --------------------- 3D models of artifacts from Roc de Combe collected for this study cannot be disseminated at the present time due to rights restrictions. For access to 3D scan data for artifacts from Roc de Combe, please contact Samantha Porter (stporter@umn.edu). Each 3D models consists of a .OBJ format file, which is associated with a .MTL and .JPG file. The 3D data in this dataset are divided into two assemblages (the Les Cottés Châtelperronian and the Les Cottés Protoaurignacian), each of which are further divided two categories of files (those corresonding to artifacts included in the sample analyzed for the associated JCAA paper listed above, and those corresponding to artifacts that had to be excluded). The files are organized into four different .ZIP files: 3_Porter_et_al_2019_JCAA_CTS_CP_included.ZIP 4_Porter_et_al_2019_JCAA_CTS_CP_excluded.ZIP 5_Porter_et_al_2019_JCAA_CTS_PA_included.ZIP 6_Porter_et_al_2019_JCAA_CTS_PA_excluded.ZIP The artifacts associated with each of the four above groups are as follows: 3_Porter_et_al_2019_JCAA_CTS_CP_included 01.

CTS_PA_Z4-3178 --------------------- EXPLANATION OF CROSS SECTION IMAGES --------------------- For all artifacts used in the final sample of the associated JCAA study (including artifacts from Roc de Combe), the following are included as part of 7_Porter_et_al_2019_JCAA_cross_sections.ZIP: • A black and white cross section image of the entire core in JPG format - files names end in "full_core" • A black and white cross section image of the core corresponding to the greatest extent of knapping in JPG format - file names end in "platform" • A composite of the above two images created in ImageJ in JPG format (see associated publication for additional information) - file names end in "imagej" For all of the above, the black square in the corner serves as a 1cm scale.
