Wạwał clay pit (Saynoceras verrucosum zone) (Cretaceous of Poland)

Also known as Wawal

Where: Poland (51.5° N, 20.1° E: paleocoordinates 43.1° N, 26.6° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Saynoceras verrucosum ammonoid zone, Late/Upper Valanginian (140.2 - 136.4 Ma)

• Material with unspecified sample number, but from the Saynoceras verrucosum zone.

• group of beds-level stratigraphic resolution

Environment/lithology: offshore; unlithified claystone and unlithified siltstone

• The faunal assemblage suggest shallow water conditions near the photic zone in the lower and upper parts of the section and a deeper water conditions in the middle part.
• dark clays and silts; sediments from the Wawal section are largely unlithified

Size classes: macrofossils, mesofossils, microfossils

Preservation: original aragonite

Collected by Kaim in 1995-2002

Collection methods: bulk, acetic, sieve,

• Repository: Institute of Paleobiology, Polish Academy of Sciences (PAS) in Warsaw (abbreviated ZPAL) and the Museum of the Earth PAS in Warsaw (abbreviated MZ).
