Leptaena rugaurita Community, Prague Basin (Silurian of Czech Republic)

Where: Czech Republic (50.0° N, 14.1° E: paleocoordinates 56.3° S, 61.3° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Monograptus belophorus zone, Motol Formation, Sheinwoodian (433.4 - 430.5 Ma)

• formation-level stratigraphic resolution

Environment/lithology: marine; gray limestone

• "Both the disarticulated brachiopods and trilobites show evidence for current and wave transport and activity...Community is restricted to a rougher water environment than [the Miraspis-Mezounia Comm.] and is assigned to about BA 3-4. The lower than normal brachiopod diversity, contrasting with more than 20 trilobite species, numerous unrevised gastropods and corals, may reflect unsuitable substrate, rougher water, or other, unrecognized restrictive factors."
• "This community is confined to gray platy, bioclastic limestone (about 2 m thick) cropping out in the Kacak Valley."

Collection methods: Authors give relative abundance data (very rare, more frequent, frequent) for brachiopods. Authors state in text that there are more than 20 trilobite species, but they list only four (dominant) species.
