Lithology and environment
| Primary lithology: | calcareous "shale" |
| Includes fossils? | Y |
| Lithology description: "The dark, commonly calcareous shales have yielded [faunal list].." | |
| Environment: | marine indet. |
| Geology comments: "The rather deep water A. konincki Comm. is poor in sessile benthos...[Chlupac assigned to BA 4-5.] Gradational realtions with the black, graptolitic shale facies suggest a BA 5 position...The rarity of sessile benthos is consistent with a lower oxygen level or possible a very soft substrate unsuited to most fixed organisms. The presence of articulated trilobites and sponges suggests a quiet water environment..." | |
