Stratigraphy
Formation:Jasna Gora
Stratigraphic resolution:bed
Stratigraphy comments: 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.
Lithology and environment
Primary lithology:concretionary,glauconitic,phosphatic lithified sandy marl
Environment:offshore shelf
Taphonomy
Modes of preservation:body,original phosphate

Temporal resolution:condensed
Collection methods and comments
Collection methods:chemical,acetic,sieve,field collection
Minimum sieve size:0.355
Rock censused:87 kg
Reason for describing collection:taxonomic analysis
Collection dates:2004
Collection method comments: 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.
