Also known as Field No. 19, Bed 17
Where: Northwest Territories, Canada (67.9° N, 135.4° W)
• Paleocoordinates: 74.1° N, 39.8° W (Wright 2013)
• coordinate stated in text
• outcrop-level geographic resolution
When: Upper Member (Mount Goodenough Formation), Barremian (129.4 - 125.0 Ma)
• 8-9 ft thick siltstone, 287-313 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. Considered to be the equivalent of bed 48, section 5.

Environment/lithology: transition zone or lower shoreface; lithified, fine-grained, gray sandstone
Size class: macrofossils
Reposited in the GSC
Collection methods: quarrying,
• Collected by Jeletzky; presumably reposited in GSC collections .
