This list of dinosaurs is a comprehensive listing of all genera that have ever been included in the superorder Dinosauria, excluding class Aves (birds, both living and those known only from fossils) and 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 dinosaurs. Many listed names have been reclassified as everything from birds to crocodilians to petrified wood. The list contains 1497 names, of which approximately 1165 are considered either valid dinosaur genera or nomina dubia.
Scope and terminology
There is no official, canonical list of dinosaur genera. The closest is the Dinosaur Genera List, compiled by biological nomenclature expert George Olshevsky, which was first published online in 1995 and is regularly updated. The most authoritative general source in the field is the second (2004) edition of The Dinosauria. The vast majority of citations are based on Olshevsky's list, and all subjective determinations (such as junior synonymy or non-dinosaurian status) are based on The Dinosauria, except where they conflict with primary literature. These exceptions are noted.
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 instances are junior synonyms. Senior synonyms are generally used, except by special decision of the ICZN (see Tyrannosaurus), 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. Preoccupied names are not valid generic names.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 (see Hadrosaurus), this term is not used on this list.Aachenosaurus – a piece of petrified woodAardonyxAbdallahsaurus – nomen nudum, probably GiraffatitanAbelisaurusAbrictosaurusAbrosaurusAbydosaurusAcanthopholisAchelousaurusAcheroraptorAchillesaurusAchillobatorAcristavusAcrocanthosaurusAcrotholusActiosaurus – a choristoderanAdamantisaurusAdasaurusAdelolophusAdeopapposaurusAegyptosaurusAeolosaurusAepisaurusAerosteonAetonyx – possible junior synonym of MassospondylusAfrovenatorAgathaumas - possible synonym of TriceratopsAggiosaurus – a metriorhynchid crocodilianAgilisaurusAgnosphitysAgrosaurus – probably a junior synonym of ThecodontosaurusAgujaceratopsAgustiniaAhshislepeltaAirakoraptor - nomen nudumAjancingeniaAjkaceratopsAlamosaurusAlaskacephaleAlbalophosaurusAlbertaceratopsAlbertadromeusAlbertonykusAlbertosaurusAlbinykusAlbisaurus – a non-dinosaurian reptileAlcovasaurusAlectrosaurusAletopeltaAlgoasaurusAlioramusAliwalia – junior synonym of EucnemesaurusAllosaurusAlnashetriAlocodonAltirhinusAltispinaxAlvarezsaurusAlwalkeriaAlxasaurusAmargasaurusAmargastegosAmargatitanisAmazonsaurusAmmosaurusAmpelosaurusAmphicoeliasAmphicoelicaudia – nomen nudum;
