The Kanguk Formation is a geological formation in the Northwest Territories and Nunavut, Canada whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.Weishampel, David B; et al. (2004). "Dinosaur distribution (Late Cretaceous, North America)." In: Weishampel, David B.; Dodson, Peter; and Osmólska, Halszka (eds.): The Dinosauria, 2nd, Berkeley: University of California Press. Pp. 574-588. .
It was first described in the Kanguk Peninsula of the Axel Heiberg Island, along the shore of the Stand Fiord by Souther in 1963.Geological Survey of Canada Map 36-1959 The formation occurs throughout the Sverdrup Basin and the southern Queen Elizabeth Islands.
Lithology The Kanguk Formation is composed of dark shale and siltstone with interbeds of sandstone, bentonite and tuff. Thicker sandstone and conglomerate beds occur in the western reaches in Eglinton Island.
Fossil content The Kanguk Formation preserves an extensive record of shelf assemblages rich in benthic foraminifera that reveal numerous pulses of local hypoxia. Fish fossils have been unearthed here.
