Hyskov, V Jakubince (Silurian of Czech Republic)

Also known as Aegironetes-Aulacopleura Comm., Zelkovice Fmn., Prague Basin

Where: Czech Republic (50.0° N, 14.1° E: paleocoordinates 61.3° S, 67.6° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Monograptus sedgwicki zone, Zelkovice Formation, Aeronian (440.8 - 438.5 Ma)

• formation-level stratigraphic resolution

Environment/lithology: marine; volcaniclastic lime mudstone and limestone

• "This community is confined to the slope or foot of a submarine volcaniclastic accumulation...The...Community is assigned to BA 4-5, and grades downslope into an anoxic environment of black graptolitic shales...Two Eocoelia specimens found at Hyskov are considered as extraneous elements probably transported in from shallower water rather than indicating BA 2. The occurrence of Stricklandia probably representes BA 4."
• "According the Halicek and Kriz (1973), the fossiliferous layers, mostly formed of muddly limestones with a tuffaceous admixture and laminated limestones, commonly with volcanic glass on bedding planes...Interlayers of balatic tuff...At about the middle part of the sequence a fed beds of light, coarse grained limestone occur with abundant [list]..."

Size classes: macrofossils, mesofossils

Collection methods: Brachiopods ranked by authors as very rare, more frequent, frequent, dominant, and uncertain [based only on old collections], but these data are not entered here.
