Locality P6502D (Cretaceous of Canada)

Also known as Anderson River

Where: Northwest Territories, Canada (69.3° N, 128.3° W: paleocoordinates 78.2° N, 70.2° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Brown Bed Member, Early/Lower Campanian (83.5 - 70.6 Ma)

• bed-level stratigraphic resolution

Environment/lithology: lagoonal or restricted shallow subtidal; poorly lithified, bentonitic, concretionary, brown shale

• "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

Collected by D. Russell in 1965
