Stratigraphy
Formation:Kopanina
Stratigraphic resolution:formation
Stratigraphy comments: "The exact stratigraphic assignment is under discussion, probably the lowest layers of the Kopanina Formation..."
Lithology and environment
Primary lithology:shelly/skeletal,yellow grainstone
Lithology description: "Fossils are contained in yellow and white coarsely biodetrital crinoidal limestones under- and overlain by volcanoclastic rocks of the Svaty Jan Centre."
Environment:marine indet.
Geology comments: "The lithology, fragmentary preservation of most fossils and the composition of the fauna clearly point to a high energy shallow water environment of thw volcanic elevation (BA 3 or up to 2)."
Taphonomy
Collection methods and comments
Collection excludes:some macrofossils
Reason for describing collection:paleoecologic analysis
Taxonomic list comments:Only trilobites are listed to genus level, but many other groups reported present.
