Kyrtogymnodon is an extinct genus of prehistoric porcupinefish that lived during the Pliocene epoch of Europe. It contains a single species, K. capellini from Italy. It can be distinguished from other porcupinefish by the arched occlusal surface of its tooth plates, and may be related to the earlier genus Progymnodon.Ortwin Schultz: Oligodiodon, ein Igelfisch aus dem Mittel-Miozän (Badenium) der Steiermark, Österreich (Diodontidae, Osteichthyes). In: Joannea – Geologie und Paläontologie 8 (2006), S. 25–46 (pdf, geologie.ac.at). An alleged earlier record of this genus from the Eocene of the eastern United States is now thought to represent an aberrant tooth plate of the bonefish relative Phyllodus.
