Where: Yukon, Canada (65.8° N, 139.9° W: paleocoordinates 70.6° N, 73.2° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Upper Sandstone Formation, Aptian (125.0 - 113.0 Ma)

• Collection a composite from the "upper sandstone division" unit of the Porcupine River headwaters section. This succession is assigned a Aptian age, although could potentially fall within the latest Barremian and the Aptian according to Jeletzky (1958).

• bed-level stratigraphic resolution

Environment/lithology: shoreface; sandstone

Size class: macrofossils

Reposited in the GSC

Collection methods: quarrying,

• Collection is a composite derived from Fig. 2 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.
