Aspidorhynchiformes
Aspidorhynchiformes is an extinct order of prehistoric ray-finned fish that was described by Bleeker in 1859.Taxonomy
Aspidorhynchiformes has one family, which is divided into at least two genera:
- Order †Aspidorhynchiformes Bleeker 1859
- * Family †Aspidorhynchidae Bleeker 1859
- ** Genus ?†Jonoichthys Gouiric-Cavalli 2015
- ** Genus ?†Ophirachis Costa 1854
- ** Genus ?†Platycerhynchus Costa 1864
- ** Genus ?†Pseudovinctifer Arratia 2015
- ** Genus ?†Richmondichthys Bartholomai 2004
- ** Genus †Aspidorhynchus Agassiz 1833 non Fitzinger 1843
- ** Genus †Belonostomus Agassiz 1834
- ** Genus †Vinctifer Jordan 1920
Fossils range have been found in the United States, France, Italy, Russia, Saskatchewan, Alberta, North Dakota, Montana, Wyoming, and Uzbekistan. These fossils range from 167.7mya to 66 mya.
Vinctifer is presumably closely related, but has several differences from the other two; though it is likely a member of the Aspidorhynchiformes, it might be treated as distinct from the Aspidorhynchidae.
