Lithology and environment
Primary lithology:shelly/skeletal "limestone"
Includes fossils?Y
Lithology description: No lithologic description, but generalized section of Barrandian (Fig. 15.2) shows this community in lithotype 6 ("various biodetrital and bioclastic limestones").
Environment:marine indet.
Geology comments: "Towards the upper part of the volcanoclastic-carbonate sequence the Plicocyrtia Comm. grades into the C-L Comm...According to Horny (1955) most of this benthic fauna was worn and even crushed during transport, thus indicating redeposition from the higher parts of the volcanoclastic elevation...An alternative...would call for a more turbulent water environment than...in the Plicocyrtia Comm. into which it grades. The C-L Comm. probably lived on the slope of the volcanoclastic accumulation in the shallow subtidal rough water BA 3 environment, where it was periodically affected by slides of tuffaceous material from higher elevations. The overall aspect suggests a BA 3 Janius Comm. Grp. assignment."
Taphonomy
Collection methods and comments
Collection excludes:some macrofossils
Reason for describing collection:paleoecologic analysis
Collection method comments: For several groups, not all taxa listed (in some cases because they're not known). Horny (1955) may be worth consulting for more complete lists on some groups.
