Fig 2. Porc-Epic Cave's stratigraphy.
Eastern profile (09W-10W) at the end of the 1974 excavation. The gamma-spectrometry age of the human mandible and the obsidian hydration ages for artefacts recovered during the 1933 excavation are indicated in green and orange respectively. 14C ages obtained from gastropod opercula are indicated in blue. Their position within the stratigraphy is approximate, as only the depth and square at which these objects were found is known, and cannot be correlated to a specific layer. This figure is similar but not identical to the image from [37], and is therefore for illustrative purposes only.
