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

• coordinate stated in text

When: MPl2 mammal zone, Zanclean (5.3 - 3.6 Ma)

Environment/lithology: coastal; mudstone

• The succession cropping out at Arcille includes marine detrital sediments dominated by yellowish, fossil-rich sandstones with intervening conglomeratic lenses passing upwards to greyish shelfal mudstones (Tinelli et al. 2012).

Size class: macrofossils

• grazing traces [from Polyplacophora] occurring on partial skeletons of the extinct sirenian Metaxytherium subapenninum
