Geography
| Country: | China | State/province: | Guizhou |
| Coordinates: | 26.7° North, 104.4° East (view map) | ||
| Paleocoordinates: | 6.1° North, 94.1° East | ||
| Basis of coordinate: | stated in text | ||
| Geographic resolution: | outcrop |
Time
| Period: | Triassic | Epoch: | Early/Lower Triassic |
| 10 m.y. bin: | Triassic 1 | ||
| Key time interval: | Griesbachian | Ammonoid zone: | Ophiceras |
| Age range of interval: | 251.90200 - 251.40000 m.y. ago |
Stratigraphy
| Formation: | Kayitou | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: "The presence of Annalepis in the WGEY sections represents the first occurrence of a typical Triassic element in the base or lower part of the Kayitou Formation, associated with the earliest Triassic ammonoid Ophiceras and marine bivalves, and is therefore regarded as earliest Triassic in age" (Chu et al. 2017) | |||||
Lithology and environment
| Primary lithology: | siltstone |
| Environment: | lagoonal |
| Geology comments: "the 65-m-thick Kayitou Formation corresponds to a shallow coastal lagoon evolving towards coastal transitional deposition, and which has yielded a mixed continental-marine biota" (Chu et al. 2017) | |
Taphonomy
| Modes of preservation: | body,mold/impression |
| Size of fossils: | macrofossils |
Collection methods and comments
| Reason for describing collection: | biostratigraphic analysis |
| Collection method comments: Repository: State Key Laboratory of Biogeology and Environmental Geology, China University of Geosciences (BGEG), Wuhan, China | |
