Where: Yukon, Canada (65.8° N, 140.4° W: paleocoordinates 64.3° N, 69.7° 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 Kandik River 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.
• bed-level stratigraphic resolution
Environment/lithology: deep-water; shale 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.
