ABSTRACT
The results obtained in the analysis of the malacological assemblage of two samples belonging to layer D of the Lower Pleistocene deposit of Barranco León (Guadix-Baza Basin) are presented. The main results obtained are the list of species of the malacological assemblage and their relative abundance, which indicate their marked aquatic character. On the other hand, despite the limitations imposed by the scarcity of taphonomic information and the caution suggested by certain indicators, a paleoenvironmental interpretation of the conditions existing at the time of the deposit is provided, based on the analysis of the ecological requirements of each taxon. These would correspond to the marginal zone of a permanent lake, oligohaline, of lentic regime, with little depth, presence of macrophytes and existence of thermal upwellings. This lake would be surrounded by littoral vegetation in what would constitute a strip of hygrophilic fl ora framed in an open space in which the climatic conditions would be more xeric in character and in we would fi nd a Mediterranean scrub otted with tree clusters.
Key words: Continental molluscs, Pleistocene, Guadix-Baza Basin, Barranco León.
