| Popis: | Systematic excavation and multidisciplinary research undertaken over three decades have deepened our understanding of the early Palaeolithic archaeology at Cueva Negra del Estrecho del Río Quípar (Caravaca de la Cruz, Murcia, Spain). New results from biochronology and combined ESR and U-series dating corroborate previous magnetostratigraphy, placing the entire excavated sequence between the Jaramillo sub-chron and the Matuyama-Brunhes boundary (i.e., ca. 990-772 thousand years ago [ka]); palaeontological and palynological findings reflect temperate environmental conditions. A bifacially-flaked limestone hand-axe was excavated one metre below the top of the Pleistocene sequence. The Equus cf. altidens tooth that provided the ESR estimate was excavated one metre below the hand-axe. Throughout its five-metre-deep sedimentary sequence, small nodules, fragments, and struck flakes make up the bulk of the Palaeolithic assemblage. Stratigraphical analysis points to undisturbed continuous sedimentary deposition above a layer of ashy sediment, encountered 4.5 m below the top of the Pleistocene sequence, which contained thermallyaltered bone and heat-shattered chert cores and flakes. Cueva Negra is among the earliest European sites with firm evidence of combustion. The U-series and ESR dating studies have been funded by the Australian Research Council Future Fellowship Grant FT150100215. M. Duval's research is currently funded by a Spanish Ramón y Cajal Fellowship (Ref. RYC2018-025221-I) J. van der Made is a participant in research project PGC2018-093925-B-C31 of the Spanish Ministry of Science, Innovation and Universities. |
