Stratigraphy
| Formation: | Kuanyinchiao | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Kuanyinchiao Bed
Bed is about 50 cm thick. Community spans Diceratograptus mirus, Paraorthograptus uniformis, and Diplograptus bohemicus Zones. Authors do not give sufficient information to tie this bed to a particular one of these zones. This collection was collected in 1980 and prepared and identified in Corvallis - distinguishes it from collection with the same name but no "*". | |||||
Lithology and environment
| Primary lithology: | black calcareous mudstone |
| Includes fossils? | Y |
| Lithology description: "bed massive...brachiopods occur as thoroughly disarticulated, well-preserved shells scattered within calcareous mudstone matrix...specimens commonly convex up, suggesting current activity...The rock is very fine grained, black, calcareous mudstone..." | |
| Environment: | marine indet. |
| Geology comments: "moderate depth, possibly BA 3, because it occurs landward of both the Pelagic Community (dominated in this region by graptolites) and the more offshore "Paracraniops"-Paramalomena Community, and is itself interpreted to be seaward of the very low diversity Paramalomena-Aegiromena Comm....moderately turbulent, well-oxygenated...absence of corals, stromatoporoids, trilobites and bryozoans...very calcareous nature of rock suggests not cold water...BA 3 or 4." | |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
Collection methods and comments
| Reason for describing collection: | paleoecologic analysis |
| Collection method comments: I have combined two collections from same locality. Abundances are given in table 2. | |
