Revision as of 12:03, 13 October 2008

This list of ichthyosaurs is a comprehensive listing of all genera that have ever been included in the order Ichthyosauria or the parent clade Ichthyopterygia, excluding purely vernacular terms. The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (nomen dubium), or were not formally published (nomen nudum), as well as junior synonyms of more established names, and genera that are no longer considered ichthyopterygian. Non-ichthyosaur ichthyopterygians shall be noted as such.

Scope and terminology

There is no official, canonical list of ichthyosaur genera but one of the most thorough attempts can be found at the "Ichthyosauromorpha" section of Mikko Haaramo's Phylogeny Archive^[1].

Naming conventions and terminology follow the International Code of Zoological Nomenclature. 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 f deprecated. Junior synonymy is often subjective, unless the kill kill kill kill kill !!!!!!!!!!!!! hahahahahahahaha loser!!!!!!1type specimen.
appeared in print but has not yet been formally published by the standards italicized on this list. Often, the formally published name will differ from any nomina nuda that describe the same specimen. In this case, these nomina nuda will be deleted from this list in favor of the published name.
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.
