Where: Yukon, Canada (67.1° N, 135.7° W)

• Paleocoordinates: 64.1° N, 41.8° W (Wright 2013)

• coordinate stated in text

• outcrop-level geographic resolution

When: North Branch Formation, Berriasian (143.1 - 137.1 Ma)

• Collection from the "North Branch Formation" unit of the Vittrekwa River section. This succession is assigned a Berresian age based on macrofossil biostratigraphy (Buchia okensis biozone of Jeletzky, 1958). Overlies conformably lower Tithonian age North Branch Formation of the Buchia mosquensis biozone.

• bed-level stratigraphic resolution

Environment/lithology: foreshore; lithified, pebbly, conglomeratic 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.
