List of prehistoric brittle stars

This list of prehistoric brittle stars is an attempt to create a comprehensive listing of all genera from the fossil record that have ever been considered to be ophiuroids, excluding purely vernacular terms.

The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (nomina dubia), or were not formally published (nomina nuda), as well as junior synonyms of more established names, and genera that are no longer considered brittle stars.

Naming conventions and terminology follow the International Code of Zoological Nomenclature (ICZN).

Technical terms used include: Acinetaster Aganaster Amphiophiura Amphioplus Antiquaster Aplocoma Archaeophiomusium Arenorbis Argentinaster Armathyraster Aspiduriella Asteronyx Aulactis Bdellacoma Brezinacantha Bohemura Cheiropteraster Cholaster Crepidosoma Drepanaster Encrinaster Eophiura Eospondylus Euzonosoma Furcaster Geocoma gorgonocephalid Hallaster Hemieurylae Kentrospondylus Klasmura Lapworthura Loriolaster Lumectaster Marginaster Mastigactis Mastigophiura Medusaster Miospondylus Nullamphiura Onychaster Ophiacantha Ophiaulax Ophiocnida Ophiocoma Ophiocrossota Ophiocten Ophioglyphoida Ophiolancea Ophiomusium Ophiopetra Ophiopinna Ophiothrix Ophiotitanos Ophiotrigonum Ophiura Ophiurella Ophiurina Ophiuriocoma Paleocoma Palaeophiura Palaeura Phragmactis Pradesura Protaster Ptilonaster Rhopalocoma Schoenaster Silesiaster Sinosura Stenaster Stephanoura Stuertzaster Syntomospina Taeniaster Tremataster Urosoma Vandelcoaster Xanthamphiura
