Monte Mario (Pleistocene of Italy)

Where: Italy (41.9° N, 12.5° E: paleocoordinates 41.7° N, 12.2° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Monte Mario Formation, Calabrian (1.8 - 0.8 Ma)

• Terebratula ampulla occurs in the Arctica islandica beds (members C1 and C2 of the Monte Mario Formation). The basal Monte Mario Formation is early Calabrian based on calcareous nannofossils, zone MNN19c, and benthic forams (Cosentino et al., 2009).

• group of beds-level stratigraphic resolution

Environment/lithology: coastal; poorly lithified, medium-grained, coarse sandstone

• Benthic foraminifers are abundant and well-preserved, and record an infralittoral environment
• Possibly from the C1 Fametto silts (clays and sandy clays) but much more likely from the well-known and fossiliferous gray sands with A. islandica (unit C2). Poorly lithified based on description/illustrations in Cosentino et al. and fossil preservation.

Size class: macrofossils

Reposited in the USNM
