In fact, relatively recently the chronology of the level TD4, where the oldest lithic industries of the site were identified, was successfully refined.
In TD1, it has likewise been possible to date a level at the base of the sedimentary fillings, where a change of magnetic polarity, identified as the Jaramillo event, was observed: this is very difficult to detect at archaeological sites in caves and it marks a very well-defined moment approximately one million years ago.
In order to carry out this dating, a leading-edge methodology was employed, combining high-resolution Uranium-Thorium analysis using laser ablation coupled to a mass spectrometer and measurements of a fragment of enamel by Electron Spin Resonance (ESR).
