Where: British Columbia, Canada (49.7° N, 125.7° W: paleocoordinates 0.5° N, 60.0° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Buttle Lake Formation, Artinskian (290.1 - 279.3 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: lithified limestone

• Medium to coarse-grained, crinoidal, sparsely fossiliferous, light-colored limestone. Nodules and irregular thin bands of light and dark chert and silicified limestone occur in zones between massive limestone beds. At least one thick bed of dark, richly fossiliferous, dolomitic limestone is present.
