“…A preliminary note by Sevink et al (1981), showing the results of K-Ar dating performed on the biotites of both a level overlying the fossiliferous beds and of the fossiliferous horizon, reveals a discrepancy between the geochronological age and the biostratigraphical age. Coltorti et al (1982) and Delitala et al (1983) claim that geochronological methods (K-Ar dating) indicate an age of about 0.5 Ma for the in situ tuffs at the top of the sequence and of 0.74 Ma for the sanidines of the colluvium overlying the archaeological site. The fact that the older age is based on colluvium suggests that the age of the site may be between 0.74 and 0.5 Ma.…”

The evolution of mammalian communities is a significant tool for reconstructing past environments and climate. In this paper, a palaeoecological and palaeoenvironmental reconstruction based on the study of the Italian mammal faunas ranging from Middle Pliocene to the Holocene is presented using the cenogram method and quantification of temperatures based on arvicolid species richness. These analyses reveal open and arid conditions during glacial periods and less open and more humid conditions during interglacials, with some differences between north and central-south Italy. Northern and Southern communities reflect similar trends in the evolution of palaeoenvironments and in the variation of the temperatures, but differences in estimated temperatures, which indicate a more temperate climate for southern Italy throughout the period, are considered here.

“…730 000 yr BP. Unsuccessful attempts have been made to locate the Matuyama-Brunhes boundary in the series (Coltorti et al, 1982;McPherron and Schmidt, 1983). During the Brunhes chron, though, some reversed events are reported (Chapman et al, 1988), such as Delta (around 0.65 Ma) and Big Lost (around 0.58 Ma).…”

“…The age of this site was for many years matter of debate among researchers. The K/Ar age of 736 ka, provided by Coltorti et al (1982), was considered too old for being in accordance with the paleontological evidences (e.g., the occurrence of A. cantianus) (Kolfschoten and Koenigswald, 1996;Petronio and Sardella, 1999). The new 40 Ar/ 39 Ar data provided by Coltorti et al (2005) assessed the age of the archeological stratum at 610-606 ka, confirming the value of the biochronological framework pointed out for Italy.…”

The tools are considered matching with an opportunistic late Mode 1 lithic industry (Coltorti et al, 1982;Peretto, 1983;Rufo et al, 2009).

Hominin responses to environmental changes during the Middle Pleistocene in central and southern Italy

The palaeobotanical record of early Palaeolithic sites from Western Europe indicates that hominins settled in different kinds of environments. During the "Mid-Pleistocene Transition (MPT)", from about 1 to 0.6 Ma, the transition from 41-ka to 100-ka dominant climatic oscillations, occurring within a long-term cooling trend, was associated with an aridity crisis which strongly modified the ecosystems. Starting from the MPT the more favorable climate of central and southern Italy provided propitious environmental conditions for long-term human occupations even during the glacial times. In fact, the human strategy of territory occupation was certainly driven by the availabilities of resources. Prehistoric sites such as Notarchirico (ca. 680–600 ka), La Pineta (ca. 600–620 ka), Gaudo San Nicola (ca. 380–350 ka) or Ceprano (ca. 345–355 ka) testify to a preferential occupation of the central and southern Apennines valleys during interglacial phases, while later interglacial occupations were oriented towards the coastal plains, as attested by the numerous settlements of the Roma basin (ca. 300 ka). Faunal remains indicate that human subsistence behaviors benefited of a diversity of exploitable ecosystems, from semi-open to closed environments. In central and southern Italy, several palynological records have already illustrated the regional and local scale vegetation dynamic trends. During the Middle Pleistocene climate cycles, mixed mesophytic forests developed during the interglacial periods and withdrew in response to increasing aridity during the glacial episodes. New pollen data from the Boiano basin (Molise, Italy), attest to the evolution of vegetation and climate between OIS 13 and 9 (ca. 500 to 300 ka). In this basin, the persistence of high edaphic humidity, even during the glacial phases, could have favored the establishment of a refuge area for the arboreal flora and provided subsistence resources for the animal and hominin communities during the Middle Pleistocene. This could have constrained human groups to migrate into such a propitious area. Regarding to the local climate evolution during the glacial episodes, the supposed displacement from these sites could be linked to the environmental dynamics solely due to the aridity increase rather than directly to the global climate changes
