Kostanjek-1 Lithofacies AB, Biofacies 2 (Panonnian) Zagreb Croatia (Miocene of Croatia)

Where: Croatia (44.9° N, 16.1° E: paleocoordinates 44.6° N, 15.8° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Late/Upper Miocene (11.6 - 5.3 Ma)

• from 1-4m above base of section within 83m thick exposure within the Panonnian stage

• group of beds-level stratigraphic resolution

Environment/lithology: lagoonal; lithified, silty marl and lithified claystone

• The succession retains the structural complex of the Sarmatian layers, but with a new type (oligohaline) fossil community which shows the constant desalinization and shallowing of the environment. The cause of the shallowing is most probably aggradational infilling of the Sarmatian lagoon and/or lifting of the sedimentary area.
• the marls are more silty and contain 70-80% of the carbonate component while clays are rich in organic detritus, granules of pyrite and limonite and have a low carbonate content. Laminae are 5-10cm thick

Size class: macrofossils

Collection methods: bulk,

• collected using the method "directed dotted sample"
