High-precision Bayesian model obtained for the Chauvet-Pont d’Arc Cave. Modeled boundaries for the start and end of each occupation phase are represented in red for the Cave Bear model (postulating a continuous occupation), in blue for the Cave Floor Charcoal model, and in orange for the Parietal model. Two distinct human occupations are clearly identified, extending from 37,000 to 33,500 y ago for the first one, and from 31,000 to 28,000 y ago for the second one. Cave bear presence in the cave is attested until 33,000 y ago.
