The Kishenehn Formation is a Paleogene stratigraphic unit in Montana. Fossil amiiforme and teleost fish have been found in outcrops of the formation's Coal Creek Member in Glacier National Park.[1] Mosquitos have also been found in the Coal Creek Member, and have been found to be hematophagous. It is considered a Middle Eocene Lagerstätte.[2]
