Felsőtárkány 3/2 (Miocene of Hungary)

Also known as FT 3/2, Felsotarkany 3/2

Where: Heves, Hungary (48.0° N, 20.4° E: paleocoordinates 47.6° N, 20.2° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: MN 9 (11.1 - 9.7 Ma)

• Felsőtárkány 3/2 occupies an intermediate stratigraphic position among the localities reported by Venczel & Hír (2013). Hutchinson & Begun (2006, Geophys. Res. Abstr. 8) assign the lower beds of the fossiliferous Miocene succession above the tuff bed of the Galgavölgi Fm. (dated 13.7±0.8 Ma) to the Kozárd Fm. and the upper beds to the Sajóvölgi Fm., but Vencel & Hír (2013) do not give a stratigraphic column and do not mention any lithostratigraphic unit.

• bed-level stratigraphic resolution

Environment/lithology: fluvial-deltaic; gray mudstone

• "The sedimentary succession [of the late Middle and early Upper Miocene in the Felsőtárkány area] is considered likely to correspond to a river-dominated delta-top, with the basal association marking an interdistributary bay environment, which becomes paludal as water level falls. Initial distal floodplain deposition is followed by more proximal sandstone deposits due to progradation of the delta southwards from the uplifted Bükk Mountains, and possible channel avulsion on the delta-top.

•Felsőtárkány is effectively situated on a palaeo-coastline during the late middle Miocene and early late Miocene. The transition from Sarmatian near-shore, shallow water and nearby upper Badenian to Sarmatian reef facies to younger delta-top floodplain facies may indicate the initiation of the final Miocene regression from this area of the Pannonian Basin." (Hutchinson & Begun, 2006).

• "compact grey mudstones" Venczel & Hír (2013)

Size classes: macrofossils, mesofossils

Preservation: original phosphate

Collected by Janos Hír in 1999–20??

Collection methods: peroxide, sieve,

• "The fossils resulted from about 21 tones [sic!] of fossiliferous sediments processed from the Felsőtárkány-Felnémet and Felsőtárkány localities (see Hír 2006). In the field, the samples were air dried and soaked in water with H2O2 and washed repetitively using a series of screens with mashes [sic!] of 0.8 and 0.6 or 0.5 mm. [...] The finds are stored at the Municipal Museum of Pásztó (MMP)." (Venczel & Hír, 2013).
