Worldwide earliest twin burial

Worldwide earliest burial of monozygotic twins identified by an interdisciplinary team around OREA's Quaternary archaeology research group. Genetic, morphological and chemical analyses of two newborns found in a double grave at the Upper Palaeolithic site Krems-Wachtberg not only show they are monozygotic twins, but also indicate different ages-at-death. This implies re-opening of the grave - a mortuary behaviour hitherto undocumented for the Gravettian.
