Exploring the Lithic Variability of the Mousterian (MIS 9–3) Open-Air Sites of the Pontine Plain (Central Italy)

This paper presents a preliminary study of the Middle Palaeolithic lithic industries recovered at six selected open-air sites in the Latium region (central Italy), part of a regional cultural complex known as the “Pontinian”. The pedo-stratigraphic analysis combined with 40Ar/ 39Ar age constraints on the sites permits us to provide for the first time a geomorphological and chronological (300–40 ka) framework for several open-air sites in central Italy. The temporal range is remarkably coincident with the Neanderthal presence in this region. Moreover, the lithic collections analysed include the oldest occurrence of a Mousterian industry in this region. The present work, therefore, provides the background context for future re-evaluation of the peculiar Pontinian techno-complex through a more in-depth technological approach and its comparison with the other Neanderthal occurrences in central Italy.
