PBDB Collection

Lochkovella-Lochkothele Community, Prague Basin (Devonian of Czech Republic)

Where: Czech Republic (50.0° N, 14.3° E: paleocoordinates 45.0° S, 52.5° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Monograptus hercynicus zone, Radotini Member (Lochkow Formation), Lochkovian (419.2 - 410.8 Ma)

• Late Lochkovian sequence below the base of the Pragian, Monograptys hercynicus Zone.

• member-level stratigraphic resolution

Environment/lithology: marine; gray lime mudstone and calcareous shale

• "The changes in grain size, layers of coarser clastic material, graded bedding, sorting of organic remains and their concentration in thin layers, all point to less stable conditions and to pulses of higher energy. Large, even very fragile shells are commonly well preserved, and articulated trilobites are present. Although short distance transport should be considered, the assemblage broadly corresponds to the original population. A deeper subtidal shelf to slope environment of medium energy is inferred within the BA 4-5 position."

• "The Lochkov Formation consists of two basic lithofacies corresponding to the Kotys Member (light gray, thicker bedded, sparitic limestones) and the Radotin Member (dark, bituminous, platy biomicrites to biosparites with shale interbeds..." "...occurring in dark, bituminous, platy biomicritic to finely biosparitic limestones, with a variable amount of dark, calcareous shale intercalations..."

Size class: macrofossils

Collection methods: NB: Trilobites of this Community were already entered in PBDB Collection 10314. Several faunal elements mentioned only at higher taxonomic levels.
