Also known as Field No. 13, Bed 10

Where: Northwest Territories, Canada (68.0° N, 135.5° W: paleocoordinates 68.5° N, 66.6° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Upper Member (Lower Shale-Siltstone Formation), Berriasian (145.0 - 139.8 Ma)

• Shale and siltstone an unspecified height above the base of the section; assigned to the Polyptchites (Tollia) cf. tolli biozone; classified as "Upper Mbr" of the "lower shale-siltstone division" in Jeletzky (1958); Jeletzky (1958) assigns this unit a Berriasian age.
