Daptinus is an extinct genus of ichthyodectid fishes within the subfamily Saurodontinae, from the Late Cretaceous (Coniacian-Campanian) Niobrara Formation of Alabama,[2] that was originally named as a species of Saurocephalus (S. phlebotomus) in 1870 by Edward Drinker Cope,[2][3] and then became a species of Saurodon in 1871, but was moved to a separate genus in 1873.[4][5] Subsequent authors listed Daptinus as a tentative, possible synonym of Saurocephalus or Saurodon leanus.[6] The holotype, which is probably the only known specimen discovered to date, is AMNH 1906,[7] which is listed as containing vertebrae (?) and portions of the cranium, the latter including the dentary, maxilla and palate.[2]
