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 221 specimen. |
