摘要：The site of Valle de las Orquídeas is the first Upper Pleistocene open-air locality excavated at Sierra de Atapuerca We have two TL dates from the terra-rossa forming the stratigraphic sequences: 27,507 ± 2,295 years BP and 29,955 ± 2,319 years BP. The archaeological record includes 306 artefacts. This assemblage is technologically homogeneous, reflecting a Middle Palaeolithic technical background, associated with some Upper Palaeolithic features. However, retouching techniques are unusual, since they move further away from that often used during both technological periods.
