The cranium as well as the mandible were subjected to a 3D digitalisation. In order to do so, 3D photogrammetry was preferred for several reasons. First, it does not require a lot of handling of the remains. Second, it necessitates a small amount of time spent on-site. Third, 3D photogrammetry is a non-invasive and reliable way to operate a photographic capture of the cranium and the mandible. Finally, the creation of the 3D model requires little post-processing. As the procedure relies solely on photography, the mandible was carefully placed on a turning table, under a dome of light. A 360° sequence of pictures were taken by rotating the table. The same was done for the mandible. Isolated teeth were not replaced in the mandible before proceeding to the photography.

The cranium and the mandible were digitalised using the software Agisoft Photoscan. The reconstructed texture allows particular features to be visible, including the red wax applied to the zygomatic bone, and the metopic suture. The red wax restauration on the left lower canine and the left central incisor on the mandible proved unstable and led to a small displacement of the teeth in the jaw from one picture to another.The area of the unstable teeth is therefore partially blurred in the 3D model and should thus not be taken into account for a potential future facial reconstruction.
