west of Casa Lama, Monte Castello (Pliocene to of Italy)

Where: Pisa, Italy (43.6° N, 10.7° E: paleocoordinates 43.6° N, 10.6° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Late/Upper Pliocene to Late/Upper Pliocene (3.6 - 0.0 Ma)

• bed-level stratigraphic resolution

Environment/lithology: marine; coarse-grained, pebbly, gray, yellow, silty sandstone and gray, sandy claystone

• "coarse-grained greyish-yellowish sands with thin pebble intercalations...grey-yellowish coarse-grained cross-bedded sands some 3-4 m thick. The latter include thin gravel layers and light brown clayey silts a few cms thick. The sands contain also intraformational clasts of clayey silts. Washed samples of this level were barren in microfossils, although fragments of marine mollusks showing evidence of transportation occur. This level is overlain by a layer of shells mixed with sand which passes upward to grey sandy clays several meters thick...these gery sandy clays are rich in Arctica islandica shells."

Size class: macrofossils
