The Atane Formation is a geologic formation in Greenland. It preserves fossil insects of Elytrulum multipunctatum, dating back to the Albian to Coniacian stages of the Cretaceous period.
The carbonaceous mudstones, sandstones and coal seams are interpreted as freshwater lake or swamp deposits representing the vertical aggradation of a subaerial to shallow, limnic floodplain to upper delta plain. There are no indications âÂÂneither palynological evidence nor the presence of pyriteâ to suggest marine or brackish-water conditions.
