Wawal, Lodz region, Lodzkie (Cretaceous of Poland)

Where: Poland (51.5° N, 20.1° E: paleocoordinates 43.0° N, 26.7° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Valanginian (139.8 - 132.9 Ma)

• Rock section of the Early- and part of the Late Valanginian; gastropodes: 37 rock samples (2.5kg each) were taken; the fish fauna can be included in the Saynoceras verrucosum Zone (Upper Valanginian)

• group of beds-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; 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

Collection methods: bulk, acetic, sieve,

• Rock samples collected over the period 1995-2002; the material is housed at the Institute of Paleobiology, Polish Academy of Sciences (PAS) in Warsaw (abbreviated ZPAL) and the Museum of the Earth PAS in Warsaw (abbreviated MZ).
