Taxonomy
Oxyrhina retroflexa was named by Louis Agassiz in an 1838 illustration,[2] which was followed by his text description in 1843.[5][a] Its holotype is a tooth of unknown provenance housed in the State Museum of Natural History, Karlsruhe.[2][5] In 1871, Henri Le Hon named Anotodus agassizii for teeth from the Pliocene of Belgium, while acknowledging that it could be the same as O. retroflexa.[1] The former species is now regarded as a junior synonym of the latter; while some authors consider it to belong to Isurus,[7] it is more widely accepted as a distinct genus of alopiid.[3][4][8]
