Vordersdorf (Miocene of Austria)

Also known as Eibiswald/Vordersdorf coal seam

Where: Styria, Austria (46.8° N, 15.5° E: paleocoordinates 46.1° N, 15.1° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Middle Member (Eibiswald Formation), Langhian (16.0 - 13.8 Ma)

• Middle Eibiswald beds; Eibiswald/Vordersdorf coal seam

•Based on mammal fauna, a Karpatian age was assigned to the Eibiswald Formation (Mottl, 1970), corresponding to MN6–MN5. However, Gruber et al. 2003 correlated the Eibiswald Formation to younger deposits of badenian age, which was corroborated by K-Ar dates of tuff samples in the coal horizon of the formation, suggesting a minimum depositional age of ~15.22Ma (Handler et al. 2006). The Badenian was redefined in Hohenbegger et al. 2014.

• bed-level stratigraphic resolution

Environment/lithology: mire or swamp; coal

Size class: macrofossils
