VGK-39, Lake Slavonia Viviparus beds (Pliocene of Croatia)

Where: Croatia (45.6° N, 16.0° E: paleocoordinates 45.5° N, 15.9° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Viviparus other zone, Pliocene (5.3 - 2.6 Ma)

• This publication introduces the new Cernikian regional stage, which corresponds to the Viviparus (=Paludina) beds, and is broadly congruent to the Pliocene and lower Pleistocene (4.5 m.y.a. to 2 m.y.a.).

•"The sample was taken from a shell accumulation entirely disturbed by the land-slide very similar to Kra-I" (PBDB collection 185963)

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine - large; unlithified, gray, yellow, muddy siltstone

• Paleolake Lake Slavonia. "The investigated region (Figure 1) represents the southern margin of the Sava depression, a NW-SE striking extensional structure filled by more than 5 km of predominantly siliciclastic Neogene deposits." "The Pannonian back-arc basin is a large Neogene extensional structure located between the Alpine, Dinaride and Carpathian fold-and-thrust belts in central and SE Europe."
• Lithology is similar to that found in PBDB collection 185963

Size classes: macrofossils, mesofossils

Collection methods: surface (float),
