Paleocoordinates:42.0° North, 26.5° East
Basis of coordinate:stated in text
Geographic resolution:small collection
Time
Period:Jurassic Epoch:Middle Jurassic
Stage:Callovian 10 m.y. bin:Jurassic 5
Key time interval:Late/Upper Callovian Ammonoid zone: Quenstedtoceras lamberti + Quenstedtoceras mariae
Age range of interval:165.30000 - 161.50000 m.y. ago
Stratigraphy
Formation:Jasna Gora
Stratigraphic resolution:bed
Stratigraphy comments: 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).
Lithology and environment

Lithology description: Sandy, glauconitic marls with numerous phosphatic concretions
Environment:offshore shelf
Taphonomy

Temporal resolution:condensed
Collection methods and comments
Collection methods:chemical,acetic,sieve,field collection
Minimum sieve size:0.355
Rock censused:64 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.
