Description

Abstract:

In many cases, mollusc species have certain climatic preferences and therefore they are sensitive to climatic change. Thus, sometimes changes in the composition of archaeomalacological assemblages through time can reflect variations in climatic conditions, which make molluscs to be an important climatic indicator. In the Cantabrian region, the analysis of 28 stratigraphic units with evidence of molluscan exploitation, ranging from Late Magdalenian (15700 cal BP) to the early Neolithic (5700 cal BP) have shown the existence of changes in the composition of shell assemblages related to climatic changes. Thus, the most common species during the colder phases of the upper Palaeolithic (Littorina littorea; Patella vulgata var. maior) decreased dramatically their presence at the start of the Holocene, while other warmth-loving species (Osilinus lineatus; Patella intermedia) increased in numbers. In the same way, an increase in exploited species diversity have been documented, which is probably showing the introduction of new species owing to the climatic improvement.
