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
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.
