espanolEn los compases finales de la ultima glaciacion, los grupos de cazadores que habitaban en la region experimentaron cambios culturales relativamente acelerados. Este trabajo aborda la ordenacion temporal del registro arqueologico y su variabilidad sincronica, tratando de integrar y hacer mas comprensibles, los cambios en las industrias y equipamiento, en las formas de la subsistencia y de organizacion, o en materia grafica. El trabajo ofrece un analisis de la informacion disponible en 1980-� [+]1986 para ese periodo, entre c 13.500/13.000 y 11.700/11.200 BP., procedente en una veintena de yacimientos en cueva distribuidos a lo largo de la region. Se ocupa de las secuencias estratigraficas, evidencias ambientales, (sedimentos, polen) y datacion absoluta, para proponer una ordenacion cronoestratigrafica vinculada a las sucesivas alternativas ambientales detectadas en la segunda mitad del Tardiglaciar. El estudio tecnico y tipologico del instrumental litico y sobre el huevo y asta, de los objetos decorados, asi como la consideracion de los restos de subsistencia (caza, pesca y recoleccion litoral), se orienta a definir las modificaciones temporales y las variaciones espaciales a lo largo del corredor cantabrico, con expresivas diferencias en su grado en ordenacion segun tipos de restos. Se trata de identificar y jerarquizar los factores implicados en la variabilidad arqueologica durante el MSFC y de discutir la relacion entre las modificaciones temporales y espaciales de distinto aspecto culturales. Al margen de una definicion arqueologica del periodo, se propone una reorientacion, referida a la forma mas usual de enfocar la intensificacion economica, producida a finales de la fase VII e inicios de la VIII, que implico un cambio mas acelerado en los aspectos tecnicos, en la composicion del espectro de recursos aprovechados, en la movilidad de los grupos y en la amplitud de las areas de aprovechamiento anual. EnglishIn the glaciation late phases, the hunter groups that lived in the Cantabrian region suffered some cultural changes relatively accelerated. This work deals with temporal arrangement of archaeological record and its synchronic variability, trying to integrate and make more understandable the changes on equipment, on subsistence, on organization way, and the changes on graphic subject. This work offers an analysis of the available information in 1980-1986 for that period, between c.13.500/13.000 � [+]and 11.700/11.200 BP, coming from twenty cave sites approximately, distributed along the Cantabrian region. It deals with stratigraphic sequences, environmental evidences (sediments, pollen) and absolute dating, in order to propose a chronostratigraphic arrangement linked to consecutive environmental alternatives detected in the second half of Late Glacial. The technical and typological study of lytic and bone tools and decorated objects, as well the consideration of subsistence remains (hunting, fishing, coastal collecting), is focused to define the temporal changes and the spatial variations along the Cantabrian corridor, with meaningful differences in organization degree according to remains type. This thesis tries to identify and organize into a hierarchy the factors involved in the archaeological variability during the MSFC, and it tries to argument the relationship between temporal and spatial changes of different cultural aspects. Leaving aside the archaeological definition of the period, it is proposed a redeployment of the most usual way to approach the economic intensification, occurred on the late phase VII-early phase VIII, that involved a more accelerated change on technical aspects , on the used resources spectrum, on the groups mobility, and change on the width of annual use areas.
