Headwaters of Bern Creek - Kingak Shale (Jurassic of Canada)

Where: Yukon, Canada (65.1° N, 140.3° W: paleocoordinates 63.7° N, 70.2° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Kingak Shale Formation, Oxfordian (163.5 - 157.3 Ma)

• Collection a composite from the "Kingak Shale" unit of the Bern Creek headwaters section. This succession is assigned a Oxfordian age based on macrofossil biostratigraphy (Buchia (Anaucella) concentrica biozone of Jeletzky, 1967), although could potentially fall within the Kimmeridgian-Callovian.

• formation-level stratigraphic resolution

Environment/lithology: offshore; sandstone and siltstone

• Mainly neritic paleoenvironments.
• Mainly sandy to pure siltstone.

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.
