Abstract
Abstract The recent excavations (2008–2009) conducted at the open-air site of Las Delicias, located in the Manzanares River valley (Madrid), have revealed new important data for the understanding of the human settlement of Central Iberia during Solutrean times. In this paper, we present a geomorphological and taphonomic study of the Pleistocene deposits of Las Delicias, a technological analysis focused on the bifacial lithic reduction processes documented at the site, new Optically Stimulated Luminescence dates, and new palynological data. Together with the existence of numerous Solutrean lithic assemblages from the early 20th century excavations of the Manzanares terraces, these new data highlight the importance of the Manzanares valley as a focus of Solutrean settlement, not only related to flint procurement but also to foraging activities. Moreover, they require reconsideration of Central Iberia as a virtually unpopulated region during the Late Pleniglacial (MIS 2), and of the associated idea of its cultural dependence on the coastal areas of the Iberian Peninsula. We propose new avenues of research aimed at approaching the central region of Iberia in its own cultural and ecological terms.
