Where: Poland (50.8° N, 19.0° E: paleocoordinates 42.0° N, 26.1° E)
• coordinate estimated from map
• small collection-level geographic resolution
When: Retrocostatum ammonoid zone, Late/Upper Bathonian (167.7 - 164.7 Ma)
• Quercinus subzone
• bed-level stratigraphic resolution
Environment/lithology: transition zone or lower shoreface; poorly lithified, black claystone
Size classes: macrofossils, mesofossils, microfossils
Collection methods: sieve,
• The samples (approx. 5kg each) were taken from each lithologically distinct horizon of the succession. They were washed with hot water and washing powder on a sieve (mesh size 0.375 mm) and fossils were picked from residues under the microscope
