The Exshaw Formation is a stratigraphical unit of Mississippian age in the Western Canadian Sedimentary Basin.
It takes the name from the hamlet of Exshaw, Alberta, and was first described in outcrops on the banks of Jura Creek, north of Exshaw by P.S. Warren in 1937. The formation is of late Famennian to middle Tournaisian age, and includes the Devonian-Carboniferous limit. The strata were deposited during the Hangenberg event, an anoxic period associated with the Late Devonian extinction.

“It is because the body is a machine that education is possible. Education is the formation of habits, a superinducing of an artificial organisation upon the natural organisation of the body.”
