Abstract

Six stratigraphically-related samples of freshwater sediments from the Middle Pleistocene paleontological site of La Polledrara di Cecanibbio to NW of Rome in the Sabatini Volcanic District (SVD) have been characterized by their mineralogical, geochemical, and Sr-Nd isotopic compositions. These volcaniclastic sediments filled a valley incised by a former watercourse flowing through volcanic rocks. The samples are composed of abundant analcite after leucite, subordinate augite, sanidine, fluorite (except for the stratigraphically-deepest and most SiO 2 -poor sample), and minor anorthite. Quartz is present only in the stratigraphically-uppermost samples. The mineralogical composition is consistent with the origin of the sediments from different source rocks of the SVD. Major and trace elements allow for distinguishing among the samples. In particular, the four stratigraphically-uppermost samples share close SiO 2 , intermediate between the contents of the other two samples. Although several chemical characteristics of the Polledrara samples can be explained by impact of supergene processes on the sediments, the overall composition supports an origin from different source rocks of the SVD, in particular the “Tufi Stratificati Varicolori di La Storta” (TFVLS) and older pyroclastic rocks. The 87 Sr/ 86 Sr ratios of the samples (0.710182–0.710433) support the distinction of the sediments based on chemistry and mineralogy, and their Sabatinian origin. The isotopic range overlaps that in the lavas of Phases III-IV of the SVD and is slightly lower than the range in the TFVLS, likely because of advanced analcitization of the sediments. The ammonium acetate extracts from the samples show a narrow isotopic range (0.709613–0.709735), which is lower than the range of the bulk sediments but close to the isotopic composition of fossil elephant remains in the Polledrara sediments. Lastly, except for the most SiO2-rich sample exhibiting a higher value (0.512227), the 143 Nd/ 144 Nd ratios of the other samples show a narrow range (0.512147–0.512171) and cannot be distinguished from each other. The isotopic range is similar to that of the TFVLS, but higher than that of Sabatinian lavas, supporting the origin of the sediments from the former rocks.

Abstract

International audience; La Polledrara di Cecanibbio (20 km from Rome) discovered in 1984, is a famous Middle Pleistocene site of the Italian peninsula (Lazio) mainly thanks to its excellent preservation state and its richness in archaeological and faunal remains. This deposit presents a typical Aurelian faunal assemblage with a large number of “elephants” specimens. A human tooth and scavenging traces on “elephants” bones were also pointed out. Palaeontological and archaeological remains are located in deposits characterized by its high percentage of white volcanic material blocks embedded in a fine matrix, laying on a fluvial volcano-sedimentary sequence. This archaeological sequence belongs to the Aurelia Formation, and was correlated to the MIS 10-9. To refine this age assignment we provided a multi-methods investigation including both $^{40}$Ar/$^{39}$Ar and ESR/U-series methods. 40Ar/39Ar measurements made on single K-feldspars minerals extracted from white pumices within the archaeological horizon suggest a deposition age of 325 ± 6 ka while the ESR/U-series analyses applied on fossil enamel teeth highlighted a minimum age of 304 ± 25 ka, in agreement with the $^{40}$Ar/$^{39}$Ar ages. These results allowed us to place with confidence the occupation as well as palaeontological assemblage of La Polledrara di Cecanibbio contemporaneously to the middle part of the MIS 9 period just after the interglacial optimum s.s. La Polledrara di Cecanibbio is hence now the most precisely and accurately dated Lower Palaeolithic site among the numerous sites from the Lazio province.

Abstract

The site of La Polledrara di Cecanibbio (Latium, Italy) is related to deposits of the PG6 Sequence (Middle Pleistocene, Aurelia Formation, MIS 10 and 9). The sediments are mainly volcaniclastic in composition, and constitute the filling of incised valleys, mainly characterized by fluvial deposits at the base, passing upward to fluvio-lacustrine and palustrine deposits containing abundant fossil mammal remains and artifacts. The arrangement of the specimens and taphonomic observations suggest that most of the transport of the bones occurred during flooding events, followed by progressive swampy phases, resulting in the formation of areas with stagnant and muddy waters where some elephants became trapped, as indicated by remains in partial anatomical articulation. Recent excavations carried out at the site permit a better definition of the palaeoenvironmental reconstruction, already partially outlined in previous publications. In particular, an area showing a close correlation between the skeleton of an elephant and human activity, allows documentation and better understanding of some aspects of human–elephant interaction, probably mainly represented by scavenging activity.
