Also known as Nasilow

Where: Poland (51.3° N, 22.0° E: paleocoordinates 43.8° N, 18.6° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Late/Upper Maastrichtian (70.6 - 66.0 Ma)

• Upper portion of 'opoka' facies (upper Maastrichtian), c. 2 m below the K/Pg boundary. The upper part of the ‘opoka’ yields cephalopod index taxa such as the coleoid Belemnella (Neobelemnella) gr. kazimiroviensis (Skołozdrówna, 1932) and the ammonites Menuites terminus (Ward and Kennedy, 1993), Pachydiscus jacquoti Seunes, 1890, Sphenodiscus binckhorsti Böhm, 1898, Baculites spp. and Hoploscaphites constrictus crassus (Łopuski, 1911) (see Machalski 2005; Keutgen et al. 2017), of late (but not latest) Maastrichtian age.

• bed-level stratigraphic resolution

Environment/lithology: lithified, cherty/siliceous chalk

Size class: macrofossils

Collected in the 1990s
