This list of specimens is a comprehensive catalogue of all the type specimens and their scientific designations for each of the genera and species that are included in the clade ornithopoda.Ornithopoda is a clade of ornithischian dinosaurs that includes some of the most common and widespread Mesozoic animals including iguanodonts, hadrosaurs, and some animals formerly called "hypsilophodonts". The clade was named by Othniel Charles Marsh in 1881[1] and roughly means "bird feet". This name is reflective of the tridactyl feet of most ornithopods, which are superficially similar to many birds. Ornithopods were among the first dinosaurs known to scientists. The first species to be described was Iguanodon, which was described in 1825 by Sir Richard Owen.[2] Today, they collectively comprise the most diverse ornithischian group.
The exact origin of ornithopods is uncertain. Some authors consider very primitive ornithischians like Nanosaurus, Hypsilophodon, and Jeholosaurus to be ornithopods,[3] while others do not.[4] Most ornithischians were ancestrally small and bipedal, which makes the taxonomy of these species complex and uncertain.[5] [6] However, they are generally agreed to have originated by the middle Jurassic and shortly thereafter, they proliferated to most of the world's continents.[7] Ornithischians in general, but especially ornithopods, saw a large degree of diversification during the early Cretaceous.[8] This culminated in the proliferation of the giant hadrosaurs across the Northern Hemisphere and even into Africa and South America.[9] Ornithopod remains are known from all of the world's continents, including Antarctica.[10]
There is no complete, canonical list of all dinosaur taxa or holotype specimens. Attempts are regularly published in the form of books, such as the Princeton Field Guide to Dinosaurs by Gregory Paul[11] and Dinosaurs: The Most Complete, Up-to-Date Encyclopedia for Dinosaur Lovers of All Ages by Thomas Holtz and Luis Rey.[12] Where appropriate, The Paleobiology Database and Fossilworks, which are both online databases of named fossil taxa, are used to supplement the entries from published encyclopedias which are missing or data-deficient.
This list will also be updated regularly as new scientific descriptions are published and new taxa are named. The most recently named ornithopod is Minqaria bata, which was described in February 2024 by Nicholas R. Longrich, Xabier Pereda-Suberbiola, Nathalie Bardet, and Nour-Eddine Jalil.[13]
Types are also used to diagnose higher-level taxa than an individual. One individual might represent the "type specimen" of a particular species. This species would in turn represent the "type species" of a particular genus, unless it is referred to a previously described genus. Most dinosaur genera are monospecific, therefore most type specimens are also the type species of their respective genera. On this list, the type species of a genus is only noted when it belongs to a genus with multiple referred species, such as Dryosaurus or Parasaurolophus. Furthermore, when an animal is different enough from its close relatives that it is given its own family, it is conventional in dinosaur systematics to name a family after the first described, most famous, or most abundant genus assigned to it. Therefore, on this list, the type species of any type genus for a family or sub-family level taxon is also noted when appropriate.
There are several different varieties of type specimen when referring to fossil animals:
All name-bearing type specimens (i.e. holotypes, lectotypes, neotypes, and syntypes) have unique entries on this list, and non-name-bearing types (i.e. paratypes, paralectotypes, topotypes, and holotypes that have been subsumed by a neotype) are noted alongside their name-bearing counterpart.
Some described species are later determined to be invalid by subsequent scientific publications. However, invalid species are sometimes resurrected, such as in the case of Brontosaurus,[14] and sometimes the validity of a species can be controversial among researchers (e.g. the case of Torosaurus and Triceratops[15] [16]). For the purposes of neutrality and completeness, all described species and genera of marginocephalians are included, even those that have been considered invalid in subsequent scientific publications.
Some ornithopod taxa are not included on this list. Nomina nuda are not included because a type does not become recognized by the ICZN until it is published in a scientific journal with a full description.
Some misidentified taxa are also not included so long as there is a scientific consensus with regard to the specimen in question. If a specimen is later referred to a taxon outside ornithopoda, it is not included on this list. However, specimens that are identified as ornithopods in publications subsequent to their initial description are included under the name they are given within ornithopoda.
Referred taxa are only included on the list as separate entries when their initial description includes a unique type specimen.
In the case of specimens with uncertain taxonomic affinity, they will be excluded unless they are considered ornithopods by the most recently published nomenclatural study of ornithischian dinosaurs, published in 2021. This excludes animals like Jeholosaurus and Thescelosaurus, which are considered basal neornithischians by the authors. This is the same definition used on the article "Ornithopoda".
