Cochrane 2 (Paleocene of Canada)

Also known as Cochrane 11; Cochrane II

Where: Alberta, Canada (51.2° N, 114.4° W: paleocoordinates 57.7° N, 92.1° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Paskapoo Formation, Ti1 (61.7 - 56.8 Ma)

• reassigned from the Porcupine Hills Formation to the Paskapoo Formation by Fox (2011)

•fossils are from "within an interval ranging from a few centimeters to a meter or so in thickness" (Fox 2011)

• group of beds-level stratigraphic resolution

Environment/lithology: fluvial-lacustrine; pebbly, shelly/skeletal, green siltstone

• "Paskapoo sediments were deposited in the channels and floodplains of small to moderate-sized rivers, and in ponds, lakes, and swamps" (Fox 2011)
• "poorly bedded grayish−green siltstones, rich in broken bivalve and gastropod shells that are accompanied by bits of coalified wood and occasional well−rounded pebbles" (Fox 2011)

Size classes: macrofossils, mesofossils

Collected by G. P. Youzwyshyn in 1988

Collection methods: bulk, chemical, sieve

• see Scott et al. 2002

•fossils were presumably collected over numerous field seasons
