| Lithology description: there are two members: lower is sandstone dominated and upper is mudstone dominated. both are siliclastic and have trace fossils. | |
| Environment: | offshore shelf |
Taphonomy
| Modes of preservation: | cast,trace,original calcite |
| Size of fossils: | mesofossils |
Collection methods and comments
| Collection methods: | mechanical,field collection |
| Collection size: | 3 specimens |
| Reason for describing collection: | taxonomic analysis |
| Collection method comments: Collection consists of two species of fauna from the Sirius Passet fauna. The fossils are preserved as central mineralization of original calcite and replacement of outer portions with clay minerals. | |
