A short Lower Pleistocene section, cropping out in SE Sicily, is studied. The sequence mainly consists of richly fossiliferous sandy layers with Arctica islandica, deposited in mid-shelf environments. Molluscs, bryozoans, serpuloideans and calcareous algae are investigated, to identify species with palaeoclimatological implications. Apart from some well-known North Atlantic molluscs, other species are identified as palaeoclimatological tools. Cooling evidence is provided by such palaeoclimatological indicators and by the increasing shell size in some species.
