Bed 14, Ogrodzieniec Quarry (Jurassic of Poland)

Where: Poland (50.5° N, 19.5° E: paleocoordinates 42.0° N, 26.5° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Jasna Gora Formation, Middle Callovian (164.7 - 161.2 Ma)

• In bed 14, the ammonites are typical of both Jason and Coronatum Zones in the middle Callovian (Barski et al. 2004), but as bed 13 is also a part of the middle Callovian, bed 14 cannot include the lowermost part of the Jason Zone.

• bed-level stratigraphic resolution

Environment/lithology: offshore shelf; lithified, concretionary, glauconitic, phosphatic, sandy marl

Size classes: mesofossils, microfossils

Preservation: original phosphate

Collected in 2004

Collection methods: chemical, acetic, sieve,

• Repository: Institute of Paleobiology at the Polish Academy of Sciences, Warsaw, under the collection number ZPAL P 12. The wet and somewhat consolidated sediment was frozen and the disintegrated material washed through a large sieve with a mesh size of 0.355 mm. The residues from the washing were dissolved in buffered acetic acid (see Jeppsson et al. 1999 for details) to concentrate phosphatic fossils, and the insoluble residues were searched under a binocular microscope.
