Where: Yukon, Canada (68.3° N, 138.3° W: paleocoordinates 66.9° N, 48.8° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Upper Shale-Siltstone Division Formation, Hauterivian (132.9 - 129.4 Ma)

• Collection a composite from the "upper shale-siltstone division" unit of the White Mountains section. This collection is from the lower part of the division, within the "Simbirskites kleini" biozone of Jeletzky (1960), which is assigned a Hauterivian age.

• bed-level stratigraphic resolution

Environment/lithology: offshore; sandstone and siltstone

Size class: macrofossils

Reposited in the GSC

Collection methods: quarrying,

• Collection is a composite derived from Fig. 8 of Jeletzky (1978), and amalgamated from occurrences of individual taxa on composite columns for individual lithostratigraphic units. Collections presumably are reposited in the Geological Survey of Canada collections.
