Resumen
The dune deposits in the northern Lanzarote islets (Islotes) show the climatic changes (by sea level oscillations) en the last 40.000 years BP. Stratigraphic and faunistic analysis, as well as radiometric data, suggest that there are at last five sedimentary stages, ocurred during sea level regressions. The last episode has been dated at the end of the isotopic stage 2 and could be related with the last negative sea level oscillation (Younger Dryas episode). The fossil terrestrial gastropoda species are the same as the present ones in Islotes, Lanzarote and Fuerteventura, with few examples of exclusive taxons
