Where: Northwest Territories, Canada (61.0° N, 117.0° W: paleocoordinates 6.2° S, 37.2° W)

• coordinate estimated from map

When: B Member (Hay River Formation), Frasnian (382.7 - 372.2 Ma)

• member-level stratigraphic resolution

Environment/lithology: marine; limestone

• "Most of Member A of the Hay River Formation is in a shaly facies and does not bear rugose corals. The first corals to appear are very rare specimens...in limy interbeds near the top of the member. Corals first appear abundantly in member B..."
