- The researchers used dental pulp from the teeth and mandibles of 10 out of 12 skeletons found at the excavation site in the village of Baume-Les-Messieurs in France.
- The skeletons were identified to be of men between the ages of 30 and 60.
- The collection, storage, and handling of the dental pulp samples were carried out in a facility that had not previously worked with SARS-CoV samples, ensuring that the findings were not a result of cross-contamination.
