ammonites
Locality P6502, Section I (sample 3) (Cretaceous of Canada)

Also known as Anderson River

Where: Northwest Territories, Canada (69.4° N, 128.1° W: paleocoordinates 78.5° N, 82.9° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Grey Beds Member, Maastrichtian (70.6 - 65.5 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 classes: mesofossils, microfossils
