Stratigraphy
Stratigraphy comments: Late Early Pleistocene, approximately 1Ma. |
Lithology and environment
Lithology description: The bones are found in a thin lense, just below the top of a layer of yellow crossbedded coarse grained sands. | |
Environment: | fluvial-lacustrine indet. |
Geology comments: A 3m section was exposed, but the sequence is deeper than this. In the unexposed sections the sandy layer forms an escarpment that can be followed for some hundred meters in the valley, suggesting a gentle north-east dip. Landscape morphology suggests a richer clay content in the underlying sediments. |
Taphonomy
Size of fossils: | macrofossils |
Associated major elements: | many |
Size sorting: | well |
Collection methods and comments
Reason for describing collection: | taxonomic analysis |
Collection method comments: Site found in a sand quarry temporarily opened in 1969 (IGF locality n. 87). Material collected and stored at the Geological & Palaeontological Museum of the University of Florence. | |
Taxonomic list comments:Equus and Dama are most abundant, most other species represented by few elements. Leptobos is very large, similar in size to the largest Olivola specimens, whilst Eucladoceros is larger still and not so slender. |
