ammonites
Coral-Leptaenid Community, Prague Basin (Silurian of Czech Republic)

Where: Czech Republic (49.8° N, 13.3° E: paleocoordinates 52.3° S, 56.7° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Motol Formation, Homerian (426.2 - 422.9 Ma)

• Age simply given as Late Wenlock.

• formation-level stratigraphic resolution

Environment/lithology: marine; shelly/skeletal limestone

• "Towards the upper part of the volcanoclastic-carbonate sequence the Plicocyrtia Comm. grades into the C-L Comm...According to Horny (1955) most of this benthic fauna was worn and even crushed during transport, thus indicating redeposition from the higher parts of the volcanoclastic elevation...An alternative...would call for a more turbulent water environment than...in the Plicocyrtia Comm. into which it grades. The C-L Comm. probably lived on the slope of the volcanoclastic accumulation in the shallow subtidal rough water BA 3 environment, where it was periodically affected by slides of tuffaceous material from higher elevations. The overall aspect suggests a BA 3 Janius Comm. Grp. assignment."
• No lithologic description, but generalized section of Barrandian (Fig. 15.2) shows this community in lithotype 6 ("various biodetrital and bioclastic limestones").

Collection methods: For several groups, not all taxa listed (in some cases because they're not known). Horny (1955) may be worth consulting for more complete lists on some groups.
