Where: Yukon, Canada (65.8° N, 140.4° W: paleocoordinates 69.3° N, 73.9° W)
• coordinate stated in text
• outcrop-level geographic resolution
When: Hauterivian to Hauterivian (132.9 - 125.0 Ma)
• Collection a composite from the "Mid-Lower Cretaceous Coal Clastics" unit of the Kandik River headwaters section. This succession is equivalent to the "Upper Shale-Siltstone Division" of Jeletzky (1958, 1961, 1978), which is assigned a Barremian-Hauterivian age based on macrofossil biostratigraphy.
• formation-level stratigraphic resolution
Environment/lithology: deltaic; carbonaceous sandstone and silty, carbonaceous shale
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.
