Kanguk Formation (Canada)

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[edit]

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[edit]

The Kanguk Formation preserves an extensive record of shelf assemblages rich in benthic foraminifera that reveal numerous pulses of local hypoxia.[4]
