Deinodus is a form genus that includes two species: the form found in the Onondaga Formation of western New York, Deinodus bennetti, and the form found in the Columbus and Limestone of central Ohio, Deinodus ohioensis. Both species are limited to the Eifelian age of the middle Devonian Period, which occurred 398-391 million years ago (Martin, 2002).
