The Ravenscrag Formation is a stratigraphic unit of early Paleocene age in the Western Canada Sedimentary Basin.[2] It was named for the settlement of Ravenscrag, Saskatchewan, and was first described from outcrops at Ravenscrag Butte near the Frenchman River by N.B. Davis in 1918.[3]
The Ravenscrag Formation includes a wide range of vertebrate and plant fossils, as well as economically significant coal seams[4] and clay deposits.[3]
