Locality P6502B (Cretaceous of Canada)

Also known as Anderson River

Where: Northwest Territories, Canada (69.4° N, 128.1° W: paleocoordinates 78.6° N, 81.6° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Grey Bed Member, Maastrichtian (72.1 - 66.0 Ma)

• bed-level stratigraphic resolution

Environment/lithology: lagoonal or restricted shallow subtidal; poorly lithified, bentonitic, concretionary, gray siltstone

• "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."

Size class: macrofossils
