Stratigraphy
Local section:Gnaszyn A Local bed:Gns1
Stratigraphic resolution:bed
Stratigraphy comments: Bullatimorphis subzone
Lithology and environment
Primary lithology:black poorly lithified claystone
Environment:transition zone/lower shoreface

Taphonomy
Modes of preservation:body
Size of fossils:macrofossils,mesofossils,microfossils
Collection methods and comments
Collection excludes:some macrofossils
Collection methods:sieve,field collection
Reason for describing collection:general faunal/floral analysis
Collection method comments: 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
Taxonomic list comments:Numbers of specimen of gastropodes, bivalves, scaphopodes and shark teeth are explicitely stated, number of echinoderms is roughly based on proportional plots; total number of echinoderms within this collection is 68 specimen.
