Where: Northwest Territories, Canada (67.9° N, 135.4° W: paleocoordinates 70.5° N, 65.8° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Upper Member (Mount Goodenough Formation), Barremian (130.0 - 125.5 Ma)

• 35-37 ft thick siltstone, 403-442 ft from base of section; from Crioceras (Hoplocrioceras) cf. redmoni biozone; classified as "upper member" of "upper shale-siltstone division" in Jeletzky (1958); Jeletzky (1958) and Fowler and Braun (1993) assign this biozone a Barremian age.

• bed-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; poorly lithified, gray sandstone

• Boreal province; nearshore depositional environment; regressive and prograding conditions.
• Sandstone, soft, dark grey, with rusty specks and inclusions.

Size class: macrofossils

Reposited in the GSC

Collection methods: quarrying,

• Collected by Jeletzky; presumably reposited in GSC collections .
