| direct u-series analysis of the lezetxiki humerus reveals a middle pleistocene age for human remains in the basque country (northern iberia). | in 1964, a human humerus was found in a sedimentary deposit in lezetxiki cave (basque country, northern iberia). the first studies on the stratigraphy, associated mammal faunal remains and lithic implements placed the deposits containing the humerus into the riss glacial stage. direct chronometric evidence has so far been missing, and the previous chronostratigraphic framework and faunal dating gave inconsistent results. here we report laser ablation u-series analyses on the humerus yielding a m ... | 2016 | 27086059 |
