Where: Yukon, Canada (67.0° N, 136.2° W: paleocoordinates 66.6° N, 67.0° W)
• coordinate stated in text
• outcrop-level geographic resolution
When: Husky Formation, Tithonian (152.1 - 145.0 Ma)
• Collection a composite from the "Husky Formation" unit of the Rock River headwaters section. This succession is assigned an upper Tithonian Portlandian=lower Tiithonian? age based on macrofossil biostratigraphy (Buchia mosquensis biozone of Jeletzky, 1967).
• formation-level stratigraphic resolution
Environment/lithology: transition zone or lower shoreface; 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.
