Where: Poland (50.8° N, 19.0° E)

• Paleocoordinates: 37.1° N, 35.2° E (Wright 2013)

• coordinate estimated from map

• small collection-level geographic resolution

When: Middle Bathonian (167.7 - 164.7 Ma)

• 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
