Direct hydroxyproline radiocarbon dating of the Lapedo child (Abrigo do Lagar Velho, Leiria, Portugal).

Abstract

The 1998 discovery of a nearly intact Gravettian human burial in the Lapedo Valley (Leiria, Portugal) propelled the Lagar Velho rockshelter to worldwide fame. The ochre-stained skeleton of the Lapedo child, a juvenile aged around four or five, exhibited a mosaic of Neanderthal and anatomically modern human features argued to reflect admixture between the two human populations. Here, we present direct compound-specific radiocarbon dates for the child's skeleton [27,780 to 28,550 calibrated years before present (cal B.P.)] and five associated bones from the burial and underlying contexts. We reassess the chronology and archaeological interpretation of the burial in light of these new dates and demonstrate the suitability of hydroxyproline radiocarbon dating for poorly preserved Paleolithic samples that otherwise fail routine radiocarbon pretreatment methods.
