Poggibonsi (Pliocene of Italy)

Where: Tuscany, Italy (43.5° N, 11.2° E: paleocoordinates 43.4° N, 11.1° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Piacenzian (3.6 - 2.6 Ma)

• Upper part of the Pliocene Val d’Elsa Basin succession. The fossiliferous deposits belong to the San Miniato Synthem and are middle Pliocene in age.

Environment/lithology: shoreface; unlithified, massive, burrowed, medium-grained, pebbly sandstone

• The study deposits are interpreted to have been formed in a shallow marine setting, and in particular as accumulating in a shoreface environment. The well-stratified sand forming the lower part of the section was probably formed in an upper shoreface, according to the grain size and dominance of plane-parallel stratification. An upper shoreface scenario is also proposed also for the crustaceous-bearing interval, although the decrease in grain size and a parallel increase in bioturbation could suggest a decrease in the hydrodynamic regime, possibly forced by a minor increase in water depth.
• Uncemented sand. Medium massive sand with isolated small pebbles characterized by a poorly-defined bedding. These deposits contain abundant cylindrical burrows.

Size class: macrofossils
