Fragmentos de cáscara de huevos de avestruz grabados hace 60.000 años


La revista PNAS publicó ayer el hallazgo de varios centenares de fragmentos de cáscara de huevo de avestruz que presentan diferentes motivos de grabado. Los fragmentos de cáscara fueron recuperados en el abrigo Diepkloff Rock Shelter, en Sudáfrica, un abrigo con sedimentos de 60.000 años de antigüedad en el que se han identificado restos de la cultura Howiesons Poort, cultura caracterizada por una tecnología lítica muy superior a la de otras culturas contemporáneas, que alcanzó logros de talla que no serían igualados hasta 25.000 años después, y que se extinguió hace 59.000 años.
