Acrille quarry (Pliocene of Italy)

Where: Italy (42.8° N, 11.3° E: paleocoordinates 42.3° N, 10.5° E)

• coordinate stated in text

When: Zanclean (5.3 - 3.6 Ma)

• These deposits can be referred in their entirety to the ‘S2 Synthem’ recognized in the Neogene sedimentary succession of Tuscany by Dominici et al. (2018). The ‘S2 Synthem’ is a large- scale, stratigraphically complex, and lithologically diverse lower Pliocene (i.e., Zanclean)

Environment/lithology: deltaic; sandstone

• The fossiliferous sandstones from which the Casatia holotype was collected were deposited in a deltaic to shoreface shallow-water setting (Tinelli, 2013)
• shallow-marine siliciclastic deposits dominated by yellowish fossiliferous sandstones with subordinate conglomeratic horizons overlain by grayish mudstones

Size class: macrofossils
