Decoroproetus-Ravozetina Community, Prague Basin (Silurian of Czech Republic)

Where: Czech Republic (50.0° N, 14.2° E: paleocoordinates 54.3° S, 59.4° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Motol Formation, Homerian (430.5 - 427.4 Ma)

• "Latest Wenlock (about Pristiograptus ludensis Zone; perhaps from the G.nassa-P.frequens to C. colonus Zone.)"

• formation-level stratigraphic resolution

Environment/lithology: marine; volcaniclastic, calcareous shale and volcaniclastic limestone

• "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."
• "...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.
