List of therapsids

This list of therapsids is an attempt to create a comprehensive listing of all genera

 that have ever been included in the Therapsida
Therapsida
Therapsida is a group of the most advanced synapsids, and include the ancestors of mammals. Many of the traits today seen as unique to mammals had their origin within early therapsids, including hair, lactation, and an erect posture. The earliest fossil attributed to Therapsida is believed to be...

), or were not formally published (nomina nuda
Nomen nudum
The phrase nomen nudum is a Latin term, meaning "naked name", used in taxonomy...

), as well as junior synonyms of more established names, and genera that are no longer considered therapsids.

The list currently contains 512 generic names.

Naming conventions and terminology

Naming conventions and terminology follow the International Code of Zoological Nomenclature
International Code of Zoological Nomenclature
The International Code of Zoological Nomenclature is a widely accepted convention in zoology that rules the formal scientific naming of organisms treated as animals...

. 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
    Nomen nudum
    The phrase nomen nudum is a Latin term, meaning "naked name", used in taxonomy...

    (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
    Nomen oblitum
    A nomen oblitum is a technical term, used in zoological nomenclature, for a particular kind of disused scientific name....

    (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
    Nomen dubium
    In zoological nomenclature, a nomen dubium is a scientific name that is of unknown or doubtful application...

    (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.
