Where: Poland (50.7° N, 18.0° E: paleocoordinates 51.0° N, 16.7° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: MN 6 (13.7 - 12.8 Ma)

• Based on the clausiliid fauna, Nordsieck (1982) revised this classification and tentatively assigned the deposits to the Neogene mammal biozones MN 6-7 (see also Kadolsky et al. 2016, Neubauer et al. 2017). The mammal fauna was later attributed to zone MN 7+8 by De Bruijn et al. (1992), which was followed by studies on terrestrial molluscs (Stworzewicz 1999a, b) and reptiles (Ivanov 2001) (see also Daxner-Höck 2010). Other investigations on mammal remains from nearby localities in Opole yielded slightly different age models (MN 6 and MN7, respectively; Kowalski & Rzebik-Kowalska 2002).
