Rhomphaiodon is an extinct genus of prehistoric sharks in the order Synechodontiformes that has been found in Late Triassic and Early Jurassic deposits located in Europe.[1] The type species R. minor was originally named as a species of Hybodus in 1837 by Louis Agassiz.[2] A second species, R. nicolensis, was added when the genus was named in 1993.[3]
