Table 3. Taxa documented at archaeological sites in Cantabrian Spain (drainage basins from west to east) with levels attributed to the LFM. The species without
dietary interest are underlined. The number of shell beads (SB) recovered at each site is also given. Only sites with no ambiguities in the definite attribution of
the materials to the LFM, and with detailed malacological analysis of the full stratigraphic sequence, are included.
Finally, the systematic review of malacological
material carried out by one of the authors (E. Álvarez-Fernández)
in recent years appears to confirm,
with small differences, the observations
made in a previous publication about the distribution
of the various gastropod species made into
adornments along the Cantabrian corridor
(Vanhaeren et al. 2005). In general, the species
seen at El Horno are the ones most commonly
found at Magdalenian sites in Cantabrian Spain
(Álvarez-Fernández 2006: 293). If we refer to definite
contexts, i.e. those with no apparent mixing of
materials belonging to different periods, we can
observe that except for Nassarius reticulatus, a
very rare species in the region with only 10 specimens
known, the species found at El Horno are
present in the Magdalenian contexts in the western
part of the region (Entrefoces, La Paloma, Las
Caldas, Cueto de la Mina…). However, if we reduce
the chronology and refer exclusively to the final
part of the Magdalenian period, we can see that,
except for Trivia sp., the other species documented
at El Horno are not common in that area. If we
only consider sites with no ambiguities in their
chronology, the single exception is the find of
Littorina obtusata at Los Canes. In the Miera valley
(Rascaño, Piélago II…) the presence of the gastropods
found at El Horno become more common,
with a more or less clear continuity in the record
towards the east as far as the interior of France
(cf. Vanhaeren et al. 2005). It is not easy to find an
explanation for this fact. Perhaps it is related to
sampling problems, as specimens of the gastropod
species being studied here are present at
late glacial sites in western Cantabrian Spain
whose chronology is uncertain. In any case, specimens
of some of the species found at El Horno
have been documented at definite Azilian sites in
the west of the region, such as Oscura de Ania or
Los Azules (Álvarez-Fernández 2006).
5. CONCLUSIONS
El Horno has provided significant information
for understanding the relationship of final
Magdalenian societies with the Bay of Biscay. This
