Geography
Country:Italy State/province:Lazio
Coordinates: 41.7° North, 13.2° East (view map)
Paleocoordinates:41.7° North, 13.1° East
Basis of coordinate:based on nearby landmark
Time
Period:Quaternary Epoch:Pleistocene
Stage:Gelasian 10 m.y. bin:Cenozoic 6
Key time interval:MN 17
Age range of interval:2.58000 - 1.80000 m.y. ago
Stratigraphy
Stratigraphy comments: Late Pliocene, Late Villanyian, similar age to St Vallier.
Lithology and environment
Primary lithology:fine sandstone
Lithology description: At CSG, the sequence is composed by laminated medium- to fine-grained yellowish sands with Fe-Mn coatings and massive fines with CaCO3 nodules in the upper part (Bellucci et al. 2014).
Environment:"floodplain"
Geology comments: The overall mammal assemblage is indicative of river channels in a flood plain, surrounded by a mix of different environments with both savannahs and wooded areas (Bellucci et al. 2014; Strani et al. 2018). This is evidence of an environmental shift towards a more open landscape, if compared with the more forested and swampy sce-nario suggested by data from the lowermost part of the sequence.
