Lithology and environment
| Primary lithology: | planar lamination lithified lime mudstone |
| Lithology description: The fossiliferous layers are thinly bedded and laminated. | |
| Environment: | basinal (carbonate) |
| Geology comments: The depositional environment of the Prosanto Formation is interpreted as a localized basin with a stratified waterbody that resulted in oxygen-depleted bottom water. | |
Taphonomy
| Modes of preservation: | body,adpression |
| Size of fossils: | macrofossils |
Collection methods and comments
| Collection methods: | mechanical | ||
| Reason for describing collection: | taxonomic analysis | ||
| Collectors: | H. Furrer | Collection dates: | 1989 |
| Collection method comments: Starting in 1989, a large number of new Prosanto Formation fossils have been discovered in systematic excavations by Heinz Furrer and his team (Zürich University). Repository: PIMUZ. | |||
