Headwaters of Kandik River - Mid-Lower Cretaceous Coal Clastics (Cretaceous to of Canada)

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

• Mainly non-marine (paludal to deltaic). Obviously fossil fauna is marine, so hence must be derived from deltaic succession.
• Coaly sandstone with considerable interbeds of coaly shale and siltstone and some thin interbeds of impure coal.

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.
