Stratigraphy
Formation:Zelkovice
Stratigraphic resolution:formation
Stratigraphy comments: Graptolite zones Demirastrites convolutus to Monograptus sedgwicki.
Lithology and environment
Primary lithology:volcaniclastic,gray,red or brown "shale"
Secondary lithology: "limestone"
Lithology description: "The lithofacies is marked by alternations of brown and grey tuffaceous shales and limestones, with distinct lamination. Trilobites are mostly disarticulated but complete specimens also occur."
Environment:marine indet.
Geology comments: "The local distribution and lithology point to an environment of submerged volcanic elevation, most likely BA 4...
Taphonomy
Modes of preservation:body
Size of fossils:macrofossils
Collection methods and comments
Collection excludes:some macrofossils
Reason for describing collection:paleoecologic analysis
Collection method comments: Very similar to Aegironetes-Aulacopleura Community of Havlicek and Storch (PBDB Coll. no. 14087), but not completely redundant with that. Trilobite species said to number "almost 30", but some rare ones are not listed. Papers by Snajdr (1978, 1986) may be able to supplement list.
Taxonomic list comments:Only trilobites are listed to genus level, but many other groups reported present.
