The Favel Formation is a stratigraphic unit of Late Cretaceous (late Cenomanian to middle Turonian) age. It is present in southern Manitoba and southeastern Saskatchewan, and consists primarily of calcareous shale. It was named for the Favel River near Minitonas, Manitoba, by R.T.D. Wickenden in 1945. The Favel Formation is richly fossiliferous and had yielded remains of a wide variety of marine animals, including the marine crocodile Terminonaris. It is also rich in organic carbon and is therefore an oil shale.
