Where: British Columbia, Canada (50.7° N, 120.1° W: paleocoordinates 21.1° N, 44.3° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: McGregor Creek Formation (Harper Ranch Group), Wordian (266.9 - 264.3 Ma)

• Limestone in the Harper Ranch Group spans a long age range based on conodonts (Orchard & Foster, 1988), including abundant Sakmarian-Kungurian ages. However the fusulinids are most consistent with a Guadalupian age, given the broader age ranges of fusulinids such as Boultonia, Dunbarula, Kahlerina, and Minojapanella. Dunbarula laudoni co-occurs with Yabeina species in its type area, suggesting a Wordian age (or possibly Capitanian).

• group of beds-level stratigraphic resolution

Environment/lithology: lithified, gray limestone

Size class: macrofossils
