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.^[2]

It was first described in the Kanguk Peninsula of the Axel Heiberg Island, along the shore of the Stand Fiord by Souther in 1963.^[3] 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.^[1] 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.^[4]
