Paleocoordinates: | 78.2° North, 70.3° 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: | 83.50000 - 70.60000 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." |

Modes of preservation: | body |
Size of fossils: | macrofossils |
Preservation of anatomical detail: | medium |
Abundance in sediment: | few |
Fragmentation: | frequent |
Spatial resolution: | parautochthonous |
