Where: Livorno, Italy (43.6° N, 10.4° E: paleocoordinates 43.5° N, 10.2° E)
• coordinate stated in text
• outcrop-level geographic resolution
When: Blue Clays Formation, Early/Lower Pliocene (5.3 - 3.6 Ma)
• The peculiarity of the geological section under study, outcropping over a cliff near Vallin Buio (Livorno), is to have the Upper Pleistocene sediments resting in contact with those of the Pliocene without any other intermediate Pleistocenic layer.
Environment/lithology: marine; lithified, blue, calcareous claystone
Size classes: macrofossils, mesofossils, microfossils
Collection methods: The largest molluscs were collected manually in the various levels of the section, while, by sieving approximately 5 dm³ of the reddish sand interspersed with and included within the limestone, some species smaller in size have been identified; the poor state of conservation of this finer fraction allowed us to find only a few specimens.
