Layers D-F at this site, which have been U/Th dated to 122±9 kilo annum (Ka) BP (Stringer et al., 1986), contain a temperate avifauna, including Calonectris diomedea and Alca torda (Harrison, 1977, 1987). The current area of sympatry of these two species is situated in an area stretching from the waters southwest of the British Isles to the western Mediterranean (Figure 2). There is no sympatric breeding of these two species today, but this might be due to the absence of suitable breeding sites for seabirds between Bretagne and Northwest Spain. The occurrence of these two species in Wales supports evidence from other sources (e.g., X X X 8 9 X X X 10 11 X 12 13 14 15 16 17 18 19 20 21 22 X X X X X X X X Mclntyre et al., 1972; Ruddiman and Mclntyre, 1976) that the Northeast Atlantic was somewhat warmer during the Eemian than during the present interglacial. THE EARLY WEICHSELIAN.—This is a climatically complex interval comprising two moderately cold stadials (IS 5b and IS 5d) and two interstadials of nearly interglacial magnitude (ISs 5a and 5c). The character of these interstadials was different in southern and northern Europe. In the south, IS 5a was, if anything, warmer than the earlier IS 5c, whereas in Scandinavia the opposite was the case (e.g., Mangerud, 1991). The extent of glaciation during the stadials is uncertain, but in Scandinavia it seems to have been mainly restricted to the mountains except in the far north. No fauna can be definitely assigned to this period, but it is possible that the fauna from Grotte de Furninha, Portugal (Tables 1, 2), for example, belongs here. X

THE EARLY WEICHSELIAN PLENIGLACIAL.—This fairly short stadial (ca. 75-60 Ka BP) was quite cold, and the Scandinavian icecap expanded as far as eastern Denmark and northern Poland. The only fauna that might be assigned to this interval is layer K at Gorham's Cave (Gibraltar), which has been dated to "Wurm I" (Hernandez Carrasquilla, 1993). This is a rather "cold" fauna {Phalacrocorax aristotelis, Alle alle, Pinguinus impennis) (Figure 3), and the presence of at least Alle alle would certainly seem to indicate pleniglacial conditions, al though layer K also has been dated (Vega Toscano, 1990) to the somewhat milder mid-Weichselian (ca. 45 Ka BP). THE MID-WEICHSELIAN INTERSTADIAL COMPLEX.—This spans the period ca. 65-25 Ka BP, during which the climate was strongly cyclic. In very general terms, it consisted of two milder interstadials, ca. 60 Ka BP and ca. 30 Ka BP, separated by a colder stadial. For most of this interval, southern Scandinavia and at least parts of the Norwegian coast were ice-free. The most interesting site from this interval is Skjonghelleren (layer G) in Norway, dated to the Alesund interstadial
