Stratigraphy
| Formation: | Kopanina | ||||
| Stratigraphic resolution: | formation | ||||
| Stratigraphy comments: Lower Kopanina. | |||||
Lithology and environment
| Primary lithology: | red or brown calcareous "shale" |
| Includes fossils? | Y |
| Lithology description: "The fauna is found in brown calcareous shales..." | |
| Environment: | marine indet. |
| Geology comments: "...the offshore facies of the Kopanina Formation deposited at greater distances from volcanic elevations. The preservation of complete exoskeletons of trilobites suggests a low energy sedimentation at greater depths, probably BA 5." | |
Taphonomy
Collection methods and comments
| Collection excludes: | some macrofossils |
| Reason for describing collection: | paleoecologic analysis |
| 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). | |
