Gyronchus is an extinct genus of prehistoric marine pycnodont fish from the Jurassic. This genus is currently treated as a wastebasket taxon, with several genera such as Macromesodon and Turbomesodon being split out of it.[1] The type species, G. oblongus Agassiz, 1844 is known from the Bathonian-aged Stonesfield Slate of England.[2] Another apparent freshwater species, G. dumblei is known from the Early Cretaceous-aged Paluxy Formation of Texas, US and the Antlers Formation of Oklahoma, but is more likely a member of Turbomesodon.[3][4][5]
