Kogosukruk Tongue of the Prince Creek Formation. This locality is approximately 100 m downstream of locality 86/47. Dark orange ironstone concretions with Quereuxia leaves derived from a yellowish-green highly bentonitic mudstone unit about half way between the river level and an notable unconformity, and approximately 2 m below a coal. A freshwater bivalve was seen in a block containing abundant Quereuxia leaves. The coal has abundant white nodules and is equivalent to that exposed at locality 86/47. Nodules in the seat earth of this coal contain abundant Parataxodium leaves and Equisetites rhizomes.
