Today, the Late Glacial interstadials Bølling and Allerød, originally defined in northern Europe, are often applied as chronozones in different palaeoclimate contexts across the Northern Hemisphere. The scientific community in both palaeoclimate research and archaeology often disregards the fact that the Meiendorf interstadial has long been identified as preceding the Bølling-Allerød sequence, and that there are lots of difficulties with the synchronization of the Oldest Dryas-Bølling-Older Dryas-sequence. Synchronization of important Central European high-resolution pollen records with the Greenland GRIP ice core demonstrates a strong climatic gradient from the South to the North of Europe over the entire Late Glacial. Therefore, the northern European interstadials (Meiendorf, Bølling, Allerød) cannot serve universally as Late Glacial chronozones with reference to their characteristic pollen compositions, even though they are of greatest importance for the understanding of the regional vegetational history. The Greenland ice cores offer continous climate information over the entire Late Glacial and may serve as chronostratigraphical type sections. In the close future, detailed synchronization of terrestrial sequences with the Greenland ice core records will be achieved, using high-precision radiocarbon calibration based on Late Glacial dendrochronologies.

RESUMEN: Durante las últimas décadas se ha venido demostrando la existencia de oscilaciones climáticas ocurridas durante del Tardiglaciar en el Hemisferio Norte por medio de correlaciones entre los diferentes tipos de archivos (sondeos glaciares y marinos y secuencias terrestres). Esto ha permitido detectar un amplio espectro de parámetros que nos ayuda a comprender mejor los cambios climáticos ocurridos en Europa. Mientras los territorios situados en el Norte y Noroeste de Europa se ven privados de la influencia directa de la Corriente del Golfo durante el Tardiglaciar, la P. Ibérica está situada en estos momentos al Este de la parte norte de dicha Corriente Noratlántica. Aquí, los cambios acaecidos parecen haber influido menos en la flora y fauna que en los territorios situados más al Norte. Sin embargo, de forma episódica, estas condiciones del Máximo Glaciar pudieron penetrar dentro de la franja norte de la P. Ibérica viéndose afectadas también las regiones del centro de este territorio. En este artículo se analizan diferentes datos de Fauna Fría (representaciones parietales, mobiliares y restos faunísticos) de determinados yacimientos peninsulares durante el Tardiglaciar, discutiéndose sus fechas absolutas y relacionándolas con las del "El Magdaleniense con Triángulos".ABSTRACT: During recent years the comparison and synchronisation of several high-resolution climate archives (ice-cores, deep sea cores and terrestrial sequences) has repeatedly shown that Late Glacial climatic oscillations were firstly very rapid and secondly, at least in the northern hemisphere, more or less simultaneous events. This database has made it possible to establish a broad spectrum of parameters which can be used to model the essential mechanisms of European Late Glacial climatic change. During phases when northern and north-western Europe lay for longer periods of time outside the direct influence of the North Atlantic Current (Gulf Stream) the tail of the current switched directly to the latitude of the Iberian Peninsula. Here, climate change had a far less severe impact on the flora and fauna than in the more northern regions, although the pattern of oscillations is the same as in Greenland or the North Atlantic. Nevertheless, several pleniglacial climatic events allowed characteristic species to reach the northern edge of the Iberian Peninsula and, during certain time-slices, to penetrate even further to the south. This paper discusses the chronological significance of typical Cold Fauna elements from specific Late Glacial sites, as represented by both skeletal remains and mobiliary and parietal art. Finally, we discuss the absolute age of the Cantabrian "Magdaleniense con Triángulos" relative to the cold climate faunal data.
