Where: British Columbia, Canada (53.4° N, 132.3° W: paleocoordinates 2.3° N, 126.7° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Carlottense ammonoid zone, Fannin Formation (Maude Group), Late/Upper Pliensbachian (189.6 - 183.0 Ma)

• Sample from limestone 120.0 m above base of section
