MDM Quarry 1, Reichert pit (Cretaceous of Canada)

Also known as Morden

Where: Manitoba, Canada (49.1° N, 97.6° W: paleocoordinates 53.3° N, 62.2° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Pembina Member (Pierre Shale Formation), Early/Lower Campanian (83.5 - 70.6 Ma)

• correlated with Sharon Springs Member in South Dakota and Wyoming by Gill and Cobban (1965) and McNeil and Caldwell (1981)

• member-level stratigraphic resolution

Environment/lithology: basinal (); black, carbonaceous shale and conglomerate

• Pembina was deposited in quiet water well below wave base, probably well removed from contemporary shores, but gypsum damage obscures evidence.
• The lower unit of the Pembina Formation, from which the fossils were collected, is a distinctive series of black, carbonaceous shales interbedded with seams of bentonite. Layer is "a bone-tooth conglomerate" that is free of selenite.

Size class: macrofossils

Collected by Isaak & Goertzen
