Lithology and environment
| Primary lithology: | lithified mudstone |
| Secondary lithology: | gray lithified "limestone" |
| Includes fossils? | Y |
| Includes fossils? | Y |
| Lithology description: siliciclasltic mudstone; distintive 'two tone' lithology, compromising centrimetre-scale interbeds of light gray lime wackstone and darker gray dolomitic siltstone | |
| Environment: | open shallow subtidal |
| Geology comments: The carbonate beds crop out as low mounds, benches and pavements, in dolines or as towers; beds marking periods of unrestricted open shelf sedimentation | |
Taphonomy
| Modes of preservation: | body,replaced with silica |
| Size of fossils: | macrofossils |
Collection methods and comments
| Collection methods: | core,acetic,field collection |
| Reason for describing collection: | biostratigraphic analysis |
