Middle and Upper Palaeolithic Bone Refitting data from La Roche a Pierrot (Saint-Cesaire, France), excavations 2013-2024

This record is about the bone refitting material found during the 2013-2024 excavations at the La Roche à Pierrot Middle and Upper Palaeolithic site (Saint-Césaire, France). It includes three files: st.cesaire.2024.fragments.csv: a CSV table, each line documents a fragment. st.cesaire.2024.connection.csv: a CSV table, each line documents a refit between two fragments (see details below). st-cesaire-2024.R: an R script, used to generate those CSV files. Note that: Some layers, having few material and no clear location in the sequence, were excluded. Also note that some categories are subcategories (i.e. sub-layers). Only physical refits are included (anatomical refitting and fresh break were excluded). Refits were recorded by set of refitting fragments (and not by pair). Consequently, for the sets including more than two fragments, it is impossible to determine the exact distribution of the refitting relationships (if fragment A refits with fragments B and C, whether fragments B and C also refit together). So, in this dataset, the refits for those sets are parsimoniously modeled as chains (by consequence, the number of relationships might be underestimated).
