Cyrtoclymenia aff. C. strigata is identified from the Upper Devonian Pinyon Peak Limestone near Salt Lake City, Utah. The age of the ammonoid, as well as the associated conodont fauna, indicates that the enclosing rocks represent the Polygnathus styriacus conodont Zone and the Clymenia and Wocklumeria ammonoid Stufen of the Famennian Stage.--Journal abstract.
