| Coordinates: | 69.3° North, 128.3° West (view map) | ||||
| Paleocoordinates: | 78.2° North, 70.2° West | ||||
| Basis of coordinate: | estimated from map | ||||

Time
| Period: | Cretaceous | Epoch: | Late/Upper Cretaceous |
| Stage: | Campanian | 10 m.y. bin: | Cretaceous 7 |
| Key time interval: | Early/Lower Campanian | ||
| Age range of interval: | 83.60000 - 72.10000 m.y. ago |
Stratigraphy
| Member: | Brown Bed |
| Stratigraphic resolution: | bed |
Lithology and environment
| Primary lithology: | bentonitic,concretionary,brown poorly lithified "shale" |
| Includes fossils? | Y |
| Environment: | lagoonal/restricted shallow subtidal |
| Glacial or sequence phase: | transgressive |
| Geology comments: "The microfossil recovery from these two sections indicates a fairly shallow, restricted marine environment."; "Therefore it seems more likely that the contact relationship between the two units is one of restricted marine deposits transgressing over shallow lagoonal sediments after a depositional hiatus." | |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
| Preservation of anatomical detail: | medium |
| Abundance in sediment: | few |
| Fragmentation: | frequent |
| Spatial resolution: | parautochthonous |
