List of crinoid genera

This list of crinoid genera is an attempt to create a comprehensive listing of all genera that have ever been considered to be crinoids, 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 crinoids.

Naming conventions and terminology

Naming conventions and terminology follow the International Code of Zoological Nomenclature (ICZN). Technical terms used include:

Junior synonym: A name which describes the same taxon as a previously published name. If two or more genera are formally designated and the type specimens are later assigned to the same genus, the first to be published (in chronological order) is the senior synonym, and all other instances are junior synonyms. Senior synonyms are generally used, except by special decision of the ICZN, but junior synonyms cannot be used again, even if deprecated. Junior synonymy is often subjective, unless the genera described were both based on the same type specimen.
Nomen nudum (Latin for "naked name"): A name that has appeared in print but has not yet been formally published by the standards of the ICZN. Nomina nuda (the plural form) are invalid, and are therefore not italicized as a proper generic name would be. If the name is later formally published, that name is no longer a nomen nudum and will be italicized on this list. Often, the formally published name will differ from any nomina nuda that describe the same specimen.
Nomen oblitum (Latin for "forgotten name"): A name that has not been used in the scientific community for more than fifty years after its original proposal.
Preoccupied name: A name that is formally published, but which has already been used for another taxon. This second use is invalid (as are all subsequent uses) and the name must be replaced. As preoccupied names are not valid generic names, they will also go unitalicized on this list.
Nomen dubium (Latin for "dubious name"): A name describing a fossil with no unique diagnostic features. As this can be an extremely subjective and controversial designation, this term is not used on this list.

Columnals

Stukalina proposed a classification of columnals.^[1]^[2] Most families in this classification are based on a single genus. It may also be that separate families have been erected for different parts of the stem of a single crinoid genus. No families have been added for columnal genera in the initial input of data in the following table. These genera may be identified by the use of "[columnal]" in the family column of the table. It should also be noted that, where the same generic name has been used for columnals and cups/crowns, there is often considerable uncertainty that they actually belong in the same genus. As studies of columnals continue, it is hoped that things will improve and a classification will emerge that is based on the whole animal.
