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 44 specimen. | |
