Where: Yukon, Canada (65.8° N, 140.4° W: paleocoordinates 66.2° N, 72.0° W)
• coordinate stated in text
• outcrop-level geographic resolution
When: Tithonian (152.1 - 145.0 Ma)
• Collection a composite from the "unnamed Upper Jurassic sandstone" unit of the Kandik River headwaters section. This succession is assigned a Portlandian=lower Tiithonian? age based on macrofossil biostratigraphy (Buchia mosquensis biozone).
• bed-level stratigraphic resolution
Environment/lithology: marine; sandy siltstone and silty 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.
