File:Dinosaur supertree.jpg

A phylogeny of most dinosaurs and major clades, illustrating the enormous diversity of dinosaurs.

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 dinosaurs have since been reclassified as everything from birds to crocodilians to petrified wood. The list contains 1237 names, of which approximately 833 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.

Arctosaurus	Adams	1875	Misident.	Late Triassic	Canada	Originally classified as a small reptile of unknown affinities, but was often classified as a sauropodomorph dinosaur. Although it has also been classified as a theropod, recent review finds that the similarities it shares with theropods are spread throughout several groups of Late Triassic reptiles, and so it cannot be assigned any more specifically than to Archosauriformes.

Asiatosaurus	Hou, Yeh, & Zhao	1975	Valid	Early Cretaceous	Mongolia; China
Astrodon	Johnston	1859	Valid	Early Cretaceous	Eastern US	Two teeth were found in the Arundel Formation near Bladensburg, Maryland and named Astrodon in 1859 by Christopher Johnston. However, Johnston did not attach a specific epithet, so Joseph Leidy is credited with naming Astrodon johnstoni (the type species) in 1865. If Johnston had attached a scientific epithet, it would have been the second dinosaur identified in the United States.

Aublysodon	Leidy	1868	Disputed	Late Cretaceous	Montana, USA	Most palaeontologists no longer recognize Aublysodon as a valid genus. It is now widely considered to be just a juvenile tyrannosaurine. The apparently unique morphological traits of a long, low snout, nonserrated teeth, and upturned dentary tip are characteristic of younger tyrannosaurines in general.

Avaceratops	Dodson	1986	Valid	Late Cretaceous	Northwest US
"Avalonia"	Seeley	1898	Preoccupied name	Late Triassic	England	Preoccupied name, now known as Avalonianus. It was first described by Seeley from teeth from the Late Triassic of England, but the name was preoccupied (Walcott, 1889), so Kuhn renamed it in 1961. It was thought to be a prosauropod, as additional, prosauropod postcranial remains were added to it (which would eventually be named Camelotia). Later analysis revealed it was actually a chimera of prosauropod remains (Camelotia) and teeth from a non-dinosaurian archosaur (or possibly an early theropod).

Becklespinax	Olshevsky	1991	Valid	Early Cretaceous	Sussex, England	The vertebrae were originally assumed to be linked with some theropod teeth and the result named Altispinax dunkeri, a species of the superfamily Megalosauroidea. Later this assignment was shown to be unjustified, as the vertebrae identified as belonging to a new species of Acrocanthosaurus, Acrocanthosaurus altispinax. In 1991 it was reassigned to a new sinraptorid genus, Becklespinax, by George Olshevsky, in honour of its discoverer.
