User:Miracusaurs/List of non-avian dinosaur species

Dinosaurs are a diverse group of reptiles that comprise at least one thousand non-avian species and more than ten thousand avian species, also known as birds. Dinosaurs were first recognized as a group by Richard Owen by 1842, who named it to include the fossil taxa Megalosaurus, Iguanodon, and Hylaeosaurus. Birds, which are the only living dinosaurs, were not recognized as part of this group until later.

Scope
This list covers every Mesozoic non-avialan dinosaur species that is currently considered valid. Dinosaurs are currently phylogenetically defined as all members of the clade composed of the most recent common ancestor of theropods, sauropodomorphs, and ornithischians, and all of its descendants; however, this list will exclude members of Avialae, which is phylogenetically defined as all taxa more closely related to modern birds than to dromaeosaurids or troodontids. However, taxa which are currently disputed to be non-avian dinosaurs (in lieu of being non-dinosaurian dinosauriforms or basal avialans), such as herrerasaurids, Archaeopteryx, and Balaur, are also included for convenience.

The concepts of which taxa are valid, dubious, and invalid are subjective. For this list, valid genera are defined as all genera listed on List of dinosaur genera that do not have a note attached to them and do not redirect to another page; their taxoboxes should also be set to within Dinosauria. Dubious genera are those who have notes but do not redirect, as well as those labeled as nomina dubia or potentially synonymous in the literature. Invalid genera are redirects or genera who have susequently been reinterpreted as being non-dinosaurian. On the other hand, dubious or invalid species are those which are written with question marks or quotation marks on the genus' page.

The list
The following is a list of all Mesozoic non-avian dinosaur species that are currently considered valid, as well as other taxa that have been synonymized in recent years. The list contains the following information:


 * Genus: The genus a taxon represents, accompanied by a citation to the description paper, with a link if possible.
 * Species: The species within a given genus.
 * Authors: The authors who named the species. If a given combination was not the original one, the authors for the current combination will be given first, followed by the original describers of the species.
 * Year: The year a species' description was physically published. If a given combination was not the original one, the year for the current combination will be given first, then the original.
 * Holotype: The name-bearing specimen of a species.
 * Formation: The geological formation/s where the species' fossils were found.
 * Age: The geological epoch and age when the fossils date to.
 * Location: The countries and first-level administrative divisions where the fossils were found.
 * Validity: The validity of a species; in addition to labels, dubious and invalid species will have gray cells.
 * Classification: The current classification a species is assigned to. Ranks are to be taken from a classification scheme devised by Justin Tweet.
 * Notes: An interesting tidbit of information about the species, or notes clarifying other aspects of the table.
 * Skeletal elements: Images of a skeletal element or a skeletal diagram of the species.
 * Life restoration: A life restoration of the species.
 * Comments: Personal comments about the diagrams and/or restorations.
