Dlouha hora near Beroun (Silurian of Czech Republic)
Also known as Encrinuraspis beaumonti-Smooth Atrypid Community, Prague Basin
Where: Czech Republic (50.0° N, 12.9° E: paleocoordinates 53.6° S, 57.3° E)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Lobograptus scanicus graptolite zone, Lower Member (Kopanina Formation), Gorstian (427.4 - 425.6 Ma)
• Lower Kopanina, early Ludlow.
• member-level stratigraphic resolution
Environment/lithology: marine; shelly/skeletal grainstone and argillaceous limestone
• "Decrease in volcanic activity...provided favorable conditions for carbonate sedimentation and the development of fauna on the NW flank of the 'syncline' whereas calc. shale sed. dominated by graptolites continued along the SE limb...The high dominance, low diversity atrypid and athyrid lenses may represent BA 2, quiet water, restrictive conditions...[various aspects of shell preservation discussed, as well as shell accumulation indicating rough water in places...] Prevalence of small, smooth brachiopods and numerous trilobites is consistent with BA 3-4 position that graded laterally in calc. shales dom. by graptolites..."
• "The sequence of calcareous shales, commonly with tuffaceous intercalations, occupying the lowermost part of the Kopanina Formation, is overlain by bioclastic limestones of the E. beaumonti Horizon of the lower Kopanina Formation..." "...biosparitic limestone and laminated, argillaceous limestones..."
Size class: macrofossils
Collection methods: Trilobites based in part on Chlupac (1987) (ref. 6191) (his Encrinuraspis-Eophacops and Encrinuraspis-Metacalymene-Prantlia assemblages). Relative abundances of brachiopods given by the authors.
