Where: Saskatchewan, Canada (49.1° N, 109.5° W)

• Paleocoordinates: 58.9° N, 64.8° W (Wright 2013)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Coal Ridge Member (Judith River Formation), Middle Campanian to Middle Campanian (83.6 - 72.2 Ma)

• Judithian based on fauna

•Rogers et al. 2016: This mid-Judith discontinuity defines the boundary between the new McClelland Ferry and overlying Coal Ridge Members of the Judith River Formation. The shallow marine sandstones that form the backstepping sequences represent the leading edge of the Bearpaw transgression in this region and are formalized as the new Woodhawk Member of the Judith River Formation in a third reference section. New 40Ar/39Ar ages indicate (1) that the mid-Judith discontinuity formed ∼76.2 Ma

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; lithology not reported

Size classes: macrofossils, mesofossils
