This list of prehistoric sea cucumbers is an attempt to create a comprehensive listing of all genera from the fossil record that have ever been considered to be holothuroidea, 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 sea cucumbers.
Naming conventions and terminology follow the International Code of Zoological Nomenclature(ICZN).
Technical terms used include: Acanthotheelia Acanthocaudina Achistrum Acutisclerus Aduncrum Alexandrites Amphitriodites Andenothyone Auricularites Bathysynactites Binoculites Calcancora Calcancorella Calcancoroidea Calclamna Calclamnella Calclamnoidea Calcligula Calclyra Clavallus Collbatothuria Conisia Cosmatites Costigerites Croneisites Crucivirga Cucumarites Curvatella Dictyothurites Elgerius Eocaudina Etheridgella Exlinella Fissobractites Frizzellus Helfriedella Hemisphaeranthos Holothuropsis Huniella Jordanocaudina Kozurella Kuehnites Mercedescaudina Micradites Microantyx Monilipsolus Mortensenites Oneirophanites Ornaticannula Pachopsites Palaeocucumaria Palaeoypsilus Palelpidia Paleochiridota Paracucumarites Parvioctoidus Parvispina Pedatopriscus Petropegia Porachistrum Praecaudina Praeeuphronides Priscoligula Priscolongatus Priscopedatoides Priscopedatus Priscularites Proholothuria Protheelia Protocaudina Pseudoexlinella Pseudostaurocumites Punctatites Ramusites Rhabdotites Rigaudites Rota Schlumbergerites Sclerothupites Semperites Solopedatus Spandelites Spinopriscopedatus Staurocumites Stichopitella Stichopites Strobilothyone Stueria Synaptites Tetravirga Thallatocanthus Theelia Triradites Uncinulina Uncinuloides Uniramosa
