Lithology and environment
| Primary lithology: | "limestone" |
| Environment: | carbonate indet. |
| Geology comments: The Dalby Limestone consists of a 19 m succession of bedded or slightly nodular calcarenites at the stratotype locality in Fjäcka, Siljan District, Sweden (Jaanusson 1960, 1963). The uppermost units often contain several thick layers of bentonites intercalated between beds of siliceous limestone, micrite or mudstone. | |
Taphonomy
| Modes of preservation: | body,original silica |
| Size of fossils: | macrofossils |
Collection methods and comments
| Reason for describing collection: | taxonomic analysis |
| Collection method comments: The material for this study was based on fieldwork collections by the first author, and museum collections at the Swedish Museum of Natural History, Stockholm (NRM), Museum of Evolution, Uppsala University (PMU), and the Geological Survey of Sweden, Uppsala (SGU).
