Lithology and environment
| Primary lithology: | volcaniclastic,red or brown calcareous "shale" |
| Secondary lithology: | volcaniclastic "limestone" |
| Includes fossils? | Y |
| Includes fossils? | Y |
| Lithology description: "...mostly tuffaceous, calcareous shales..." "...[some fossils] occur in beds of tuffaceous limestone..." From Chlupac (1987) (PBDB ref. 6191): "...soft brown thinly laminated calcareous shales..." for Raphiophora-Rabuloproetus Assemblage. | |
| Environment: | marine indet. |
| Geology comments: "The lateral transition of the brachiopod bearing, commonly laminated, calcareous shales of this community into graptolitic shale suggests a BA 5-6 assignment. This is in full accord with trilobite ecology; Chlupac (1987) assigned the trilobites of teh Borek locality at Suchomasty to his Raphiophorus-Rabuloproetus Assemblage, and suggested that it represented the deepest habitat in the Prague basin, with a BA 5-6 position." | |
