Lithology and environment
| Primary lithology: | lime mudstone |
| Secondary lithology: | calcareous "shale" |
| Includes fossils? | Y |
| Lithology description: "Mostly disarticulated bivalves occur in lenticular, dark, micritic limestones with dark, calcareous shale intercalations." | |
| Environment: | marine indet. |
| Geology comments: "High diversity, relatively high pop. densities...Deposit feeders absent. Prevailing infaunal and reclining forms corresond to soft bottom conditions, high diversity speaks for favorable conditions for suspension feeders. The bottom was within reach of low current activity (nektobenthic cephalopods and graptolites are current oriented). Sed. rate relatively low (disartic. shells) and the bottom below wave base (good preservation)." | |
Taphonomy
Collection methods and comments
| Collection excludes: | some macrofossils |
| Reason for describing collection: | paleoecologic analysis |
| Collection method comments: Life modes and abundances given for bivalves. List based only on type locality (table 16.14). | |
| Taxonomic list comments:Bivalves are focus of this publication. Other taxa mentioned but not listed in detail. Taxa listed for this community but not explicitly stated to occur at type locality are: Gastropods (e.g. Platyceras, Orthonychia, Spirina), cephalopods, monoplacophorans (Drahomira), graptolites, Scyphocrinites, Ceratiocaris, Pterygotus, and ostracodes. | |
