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: Quenstedtoceras lamberti + Quenstedtoceras mariae ammonoid zone, Jasna Gora Formation, Late/Upper Callovian (164.7 - 161.2 Ma)
• The ammonite assemblage found in bed 16 includes both Quenstedtoceras lamberti and Q. mariae (Rozycki 1953; Barski et al. 2004), diagnostic fossils for the uppermost Callovian and lowermost Oxfordian, respectively. This bed most likely spans the boundary of these two stages and is dated to include both Lamberti and Mariae Zones (Dembicz and Praszkier 2003; Barski et al. 2004).
• 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.
