Lithology and environment
| Primary lithology: | shelly/skeletal,gray "limestone" |
| Includes fossils? | Y |
| Lithology description: "...light grey crinoidal limestones predominate..." | |
| Environment: | marine indet. |
| Geology comments: "Trilobite remains are still more fragmented and a shallow subtidal zone of higher energy BA 3 may be assumed." | |
Taphonomy
Collection methods and comments
| Collection excludes: | some macrofossils |
| Reason for describing collection: | paleoecologic analysis |
| Collection method comments: Similar to PBDB collection 14111 (P. archiaci-Atrypoidea modesta Comm. of Havlicek and Storch 1999), but not identical. | |
| Taxonomic list comments:Only trilobites are listed to genus level, but many other groups reported present. Also, not all trilobites listed (see Snajdr 1985 for possible additional encrinurines). | |
