Geography
| Country: | Japan |
| Coordinates: | 35.4° North, 137.0° East (view map) |
| Paleocoordinates: | 17.4° North, 139.8° East (Wright 2013) |
| Basis of coordinate: | estimated from map |
Time
| Period: | Triassic | Epoch: | Late Triassic |
| Stage: | Carnian | 10 m.y. bin: | Triassic 3 |
| Key time interval: | Carnian | Zone: | Capnuchosphaera |
| Age range of interval: | 237 - 227.3 m.y. ago |
Stratigraphy
| Local section: | NCU15 | Local bed: | 9.75 m | ||
| Stratigraphy comments: sample at 9.75m (Fig. 3); studied sections are in the Kamiaso unit, which consists of thrust sheets of sedimentary sequences containing Triassic to Lower Jurassic bedded cherts and overying Middle Jurassic clastic rocks (sandstones, mudstone); studied thin sections (N and O) are located in the CH-2 thrust sheet | |||||
Lithology and environment
| Primary lithology: | green chert |
| Includes fossils? | Y |
| Environment: | basinal (siliceous) |
| Geology comments: absence of carbonate rocks suggests that the primary depositional site was deeper than CCD, and beyond the reach of terrigenous clastic material | |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | microfossils |
Collection methods and comments
| Reason for describing collection: | biostratigraphic analysis |
