RESUMEN: La excavación arqueológica del yacimiento del Puente de los Tres Ojos, próximo a la calle Cerro Negro (Madrid), ha aportado nuevos datos para profundizar en el conocimiento de la ocupación humana y en la reconstrucción paleoambiental del valle del antiguo arroyo Abroñigal, cuyo curso fluvial funcionó como afluente del río Manzanares posiblemente desde antes del Pleistoceno Superior hasta la segunda mitad del siglo XX. En el presente artículo se incluyen los aspectos geomorfológicos y cronoestratigráficos de los niveles excavados, documentándose varias secuencias fluviales y aluviales de relleno de la margen derecha del fondo de valle del Abroñigal en su tramo inferior. Durante la excavación se registró un amplio conjunto lítico, formado en su mayoría por piezas recuperadas en niveles de arenas y gravas correspondientes a episodios fluviales de media energía, a las que hay que añadir un porcentaje menor localizado en niveles de limos arcillosos y arenas finas. La mayor parte del conjunto lítico responde a sistemas técnicos propios del Paleolítico Medio, aunque destaca la presencia testimonial de piezas del Paleolítico Superior, además derestos de fauna de mamíferos correspondientes al Pleistoceno Superior, todo ello en niveles datados por OSL entre 14.400 y 11.170 años BP aproximadamente.
ABSTRACT: The archaeological excavation of the Puente de los Tres Ojos site, next to Cerro Negro Street (Madrid), has provided new data that has allowed us to go in depth into the human settlement and the palaeoenvironmental reconstruction of the old Abroñigal stream valley, whose fluvial course worked as a tributary of the Manzanares River probably from before the Late Pleistocene up to the second half of the XXth century. In this paper we present the geomorphological and chronostratigraphic data of the excavated layers, documenting the various sequences of the fluvial and alluvial deposits that have filled the right bank of the Abroñigal valley bottom within its lower stretch. A large collection of lithic pieces has been obtained during the excavation works, most of which have been found within medium energy deposits of sands and gravels, being the rest associated to argillaceous slimes and thin sand deposits. The majority of the lithic collection responds to technical systems of the Middle Palaeolithic, although it is noteworthy the testimonial presence of pieces belonging to the Upper Palaeolithic, as well as mammal faunal remains from the Late Pleistocene. The dates obtained through OSL place the chronology of the deposit between approximately 14,400 and 11,170 years BP.
