Blade and bladelet production at Hohle Fels Cave, AH IV in the Swabian Jura and its importance for characterizing the technological variability of the Aurignacian in Central Europe - Fig 3

<p>(A) Calibrated radiocarbon ages of the Aurignacian stratigraphy of Hohle Fels Cave. Calibrated with Calpal-Hulu [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0194097#pone.0194097.ref013" target="_blank">13</a>]. (B) Radiocarbon data of the Aurignacian stratigraphy of Hohle Fels Cave including its upper and lower boundaries. Calibrated with Calpal-Hulu [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0194097#pone.0194097.ref013" target="_blank">13</a>]. The yellow borders indicated the most appropriate time-span of the respective archaeological horizons in relation to environmental information and absolute calibrated data of neighbouring horizons.
