Torrente Meduna sample 19 (Miocene of Italy)

Also known as Venus-Conus community sample 19

Where: Pordenone, Italy (46.2° N, 12.8° E: paleocoordinates 46.0° N, 12.6° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Bier Pudingstone Formation, Tortonian (11.6 - 7.2 Ma)

• Miocene Torento-Meduna sequence unconformably overlies the Eocene Clauzetto Flysch (Flysch di Clauzetto) and is composed of Preplans Sandstone, Zouf marl, Rugo Mizza Sandstone, San Martino Calcarenite, Torrente Meduna Siltstone, Maraldi Sandstone, Bier Puddingstone, and Montello Conglomerate. Thickness of the Bier Puddingstone is approximately 150 m. Sample 19 is from the upper part of the Bier Puddingstone.

• bed-level stratigraphic resolution

Environment/lithology: deltaic; lithified, fine, yellow conglomerate

• "....the unit is infferred to be of Tortonian age because of its stratigraphic position".
• Bier Puddingstone "consists of well cemented conglomerate beds 1-10 m thick; intercalations of silty sand of variable thickness are observed".

Size class: macrofossils

Collection methods: bulk,

• Based on single bulk samples, about 30 cubic centimetres each. Grain size data also provided.
