| Formation: | Dengying |
Member: | Kuanchuanpu |
| Stratigraphic resolution: | member |
| Stratigraphy comments: Zone assingment based on personal exptertise (Na 2011); Kuanchuanpu often is called just "Upper Member". |
| Primary lithology: | phosphatic lithified "limestone" |
| Lithology description: phosphatic limestone |
| Environment: | marine indet. |
| Modes of preservation: | original phosphate,replaced with phosphate |
| Size of fossils: | mesofossils,microfossils |
| Collection methods: | chemical,field collection |
| Reason for describing collection: | taxonomic analysis |
| Collection method comments: C. spinatus - preserved in calcium phosphate, presumably apatite, replacement of soft parts with phosphate and recrystalization of a pre-existing phosphatic skeleton. Also occasional steinkers. Hexaconularia - fragmented with prominent ribbing and well-defined grooves. Carinachites have a tubicolous interpretation |
