Bone refits from the Cuzoul de Gramat Mesolithic layers (archaeological site, France)

<p>The <a href="https://fr.wikipedia.org/wiki/Gramat#L'abri_du_Cuzoul" target="_blank" rel="noopener">Cuzoul de Gramat</a> is a Prehistoric site located in Gramat, France. Excavation determined Mesolithic and Early Neolithic occupations. This dataset concerns the physical refits determined in the Mesolithic faunal material from two sectors of the site, the South section and the Cave.</p> <p>This record includes:</p> <ul> <li><strong>cuzoul-south-fragments.csv</strong>: a (9 x 239) table, each line describes a bone object from the South section.</li> <li><strong>cuzoul-south-connection.csv</strong>: a (2 x 135) table, each line contains the unique identifiers of two refitting bone pieces from the South section.</li> <li><strong>cuzoul-cave-fragments.csv</strong>: a (9 x 239) table, each line describes a bone object from the Cave sector.</li> <li><strong>cuzoul-cave-connection.csv</strong>: a (2 x 66) table, each line contains the unique identifiers of two refitting bone pieces from the Cave sector.</li> <li><strong>Rscript-cuzoul-fragments.R</strong>: an R script to generate additional variables in the <em>-fragments.csv</em> tables.</li> </ul> <p>The <em>-fragments.csv</em> tables includes the following variables:</p> <ul> <li><strong>id</strong>: fragment unique identifier</li> <li><strong>layer</strong>: stratigraphic layer</li> <li><strong>sub.layer</strong>: stratigraphic sub-layer</li> <li><strong>square</strong>: grid square where the bone piece was found</li> <li><strong>zmin</strong>: minimal depth of the location where the bone fragment was found (in metre)</li> <li><strong>zmax</strong>: maximal depth of the location where the bone fragment was found (in metre)</li> <li><strong>thickness</strong>: thickness of the fragment (in centimetre)</li> <li><strong>length</strong>: length of the fragment (in centimetre)</li> </ul> <p>and the following variables which are derived from the latest (using the Rscript-cuzoul-fragments.R script):</p> <ul> <li><strong>surface</strong>: approximated surface of the fragment, product of the thickness by the length (in square centimeter)</li> <li><strong>x</strong>: x coordinate of the grid square where the bone fragment was found (in centimetre)</li> <li><strong>y</strong>: y coordinate of the grid square where the bone fragment was found (in centimetre)</li> <li><strong>z</strong>: approximated z coordinate of the location where the bone fragment was found (in centimetre)</li> </ul>
