Pachyacanthus is an extinct genus of toothed whale that lived about 15.97 to 2.589 million years ago (Miocene and Pliocene). It contains the single species Pachyacanthus suessi. The genus is known from European deposits in Hungary, Kazakhstan, Austria and Italy.^[1]^[2] The type specimen consisted of a few fragments of a rostrum and two fragmentary tympanic bullae. Skeletons from the Sarmatian (Middle Miocene) of Austria did not include skulls.^[3]
