GSC Loc. O-102110. Southampton Island (Ordovician of Canada)

Where: Northwest Territories, Canada (64.4° N, 84.5° W: paleocoordinates 5.1° S, 43.1° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Amplexograptus inuiti graptolite zone, Boas River Formation, Richmondian (449.6 - 445.5 Ma)

• Was Maysvillian. However, Zhang (2017: CJES) notes that it is in the Amplexograptus inuiti zone. Zhang also notes that the Boas River is not a proper unit, and that these are just lower beds of the Foster Bay formation.
