Resumen
- Excavations at Can Sadurní Cave since 2012 have uncovered a complex stratigraphy for the Middle Neolithic phase (ca. 4700-4000 cal. BC). This was not in agreement with our expectations from the previous excavation of a trial trench, where only 4 layers (10, 10b, 11 and 11b) were uncovered. After excavating a funerary layer with several in situ burials and further deposits containing multiple layers of burnt dung (fumier), the stratigraphy was revised and 5 episodes within layer 11 were detected. It became necessary to find a tool to refine the chronological sequence of these uses, under the premise that it is unlikely that the cave was used as a funerary area and a byre at the same time. Bayesian modelling allowed distinguishing these two phases, establishing an earlier use of the cave for animal herding purposes (ca. 4700-4450 cal. BC) and a funerary use of the cave in a more recent period (ca. 4400-4200 cal. BC).
