The Devonian Swan Hills reef complexes of western Canada contain a prolific and well-preserved stromatoporoid fauna. Species of the genera Hermatostroma, Atelodictyon, Stromatopora, Parallelopora, Ferestromatopora, and Clathrocoilona are common constituents of the reef, fore-reef, and reef platform limestones. Specimens from six reef complexes (Snipe Lake, Goose River, Kaybob, Virginia Hills, Swan Hills, and House Mountain) are described. Most species occur in several growth forms although one growth form is usually predominant. Two new species, Clathrocoilona sp. and Stromatopora sp., are recognized in the Swan Hills material.
