Tarbosaurus ( ; meaning "alarming lizard") is a genus of large tyrannosaurid dinosaur that lived in Asia during the Maastrichtian age of the Late Cretaceous epoch. It contains the type and single species Tarbosaurus bataar, which is known from the Nemegt Formation of Mongolia, with more fragmentary remains found further afield in the Subashi Formation of China. Tarbosaurus is represented by dozens of fossil specimens, including several complete skulls and skeletons. These remains have allowed studies focusing on its phylogeny, skull mechanics, and brain structure. Further fossil remains have b

Gallimimus ( ) is a genus of theropod dinosaur that lived in what is now Mongolia during the Late Cretaceous period. Several fossils in various stages of growth were discovered by Polish-Mongolian expeditions in the Gobi Desert of Mongolia during the 1960s; a large skeleton discovered in this region was made the holotype specimen of the new genus and species Gallimimus bullatus in 1972. The generic name means "chicken mimic", referring to the similarities between its neck vertebrae and those of the Galliformes. The specific name is derived from bulla, a golden capsule worn by Roman youth, in r

Avimimus ( ), meaning "bird mimic" (Latin avis = bird + mimus = mimic), is a genus of oviraptorosaurian theropod dinosaur, named for its bird-like characteristics, that lived in the late Cretaceous in what is now Mongolia, during the Maastrichtian.

Therizinosaurus (; meaning 'scythe lizard') is a genus of very large therizinosaurid dinosaurs that lived during the Late Cretaceous period in what is now Asia. It contains a single species, Therizinosaurus cheloniformis, known from the fossiliferous Nemegt Formation. The first remains of Therizinosaurus were found in 1948 by a Mongolian field expedition in the Gobi Desert and later described by Evgeny Maleev in 1954. The genus is only known from a few bones, including gigantic manual unguals (claw bones), from which it gets its name, and additional findings comprising fore and hindlimb elemen

Saurolophus (; meaning "lizard crest") is a genus of large hadrosaurid dinosaur that lived during the Late Cretaceous period of North America and Asia, in what is now the Horseshoe Canyon and Nemegt formations respectively (about 70 to 66 million years ago). It is one of the few dinosaur genera known from multiple continents. The type species, S. osborni, was described by Barnum Brown in 1912 from Canadian fossils. A second valid species, S. angustirostris, is represented by numerous specimens from Mongolia, and was described by Anatoly Konstantinovich Rozhdestvensky. Saurolophus is distinguis

Deinocheirus ( ) is a genus of large ornithomimosaur that lived during the Late Cretaceous around 70 million years ago. In 1965, a pair of large arms, shoulder girdles, and a few other bones of a new dinosaur were first discovered in the Nemegt Formation of Mongolia. In 1970, this specimen became the holotype of the only species within the genus, Deinocheirus mirificus; the genus name is Greek for "horrible hand". No further remains were discovered for almost fifty years, and its nature remained a mystery. Two more complete specimens were described in 2014, which shed light on many aspects of

Mononykus ( , sometimes ; meaning "one claw") is a genus of alvarezsaurid dinosaur that lived during the Late Cretaceous in what is now Mongolia, specifically the Nemegt Formation. Mononykus was a very small theropod, estimated around in length with a weight of . As in Shuvuuia, Mononykus likely developed a shaggy feathering. It was lightly built with long, thin legs and highly reduced and specialized forelimbs that were likely used for foraging termite mounds or other insect colonies.

Alioramus (; meaning 'different branch') is a genus of tyrannosaurid theropod dinosaurs from the Late Cretaceous period of Asia. It currently contains two species. The type species, A. remotus is known from a partial skull and three foot bones recovered from the Mongolian Nemegt Formation, which was deposited in a humid floodplain. These remains were named and described by Soviet paleontologist Sergei Kurzanov in 1976. A second species, A. altai, known from a much more complete skeleton also from the Nemegt Formation, was named and described by Stephen L. Brusatte and colleagues in 2009. Its r

Homalocephale (from Greek ὁμαλός, homalos, "even", and κεφαλή, kephalē, "head") is a genus of pachycephalosaurid dinosaur that lived during the Late Cretaceous period of what is now the Nemegt Formation, Mongolia. The genus was described in 1974 by Halszka Osmólska and Teresa Maryańska, and consists of a single species, H. calathocercos. Though Homalocephale has been regarded as a synonym (and juvenile form) of Prenocephale, juvenile specimens of the latter indicate that they were distinct. Homalocephale was long and possibly an omnivore.

Adasaurus ( ; meaning "evil lizard") is a genus of dromaeosaurid dinosaur that lived in Asia during the Late Cretaceous period. The genus is known from two partial specimens found in the Nemegt Formation of Mongolia that were partially described in 1983 by the paleontologist Rinchen Barsbold.

Raptorex is a controversial genus of tyrannosaurid dinosaur. Its fossil remains consist of a single juvenile specimen probably uncovered in Mongolia, or possibly northeastern China. The type species is R. kriegsteini, described in 2009 by Sereno and colleagues. The genus name is derived from Latin ', "robber", and ', "king". The specific name honours Roman Kriegstein, a survivor of the Holocaust, whose son Henry Kriegstein donated the specimen to the University of Chicago for scientific study.

Saichania (Mongolian meaning "beautiful one") is a genus of herbivorous ankylosaurid dinosaur from the Late Cretaceous period of Mongolia and China. The first fossils of Saichania were found in the early 1970s in the Baruungoyot Formation. In 1977, the type species Saichania chulsanensis was named.

Tarchia (meaning "brainy one") is a genus of herbivorous ankylosaurid dinosaur from the late Cretaceous of Mongolia.

Prenocephale (meaning "sloping head") is a genus of small pachycephalosaurid dinosaur from the Late Cretaceous Nemegt Formation of Mongolia. It was similar in many ways to its close relative, Homalocephale.

Nemegtosaurus (meaning "reptile from the Nemegt") was a sauropod dinosaur from the Late Cretaceous Period of what is now Mongolia. Measuring an estimated long and weighing , it was named after the Nemegt Basin in the Gobi Desert, where the remains — a single skull — were found. The skull resembles diplodocoids in being long and low, with pencil-shaped teeth. However, recent work has shown that Nemegtosaurus is in fact a titanosaur, closely related to animals such as Saltasaurus, Alamosaurus, and Rapetosaurus.

Opisthocoelicaudia is a genus of sauropod dinosaur of the Late Cretaceous Period discovered in the Gobi Desert of Mongolia. The type species is Opisthocoelicaudia skarzynskii. A well-preserved skeleton lacking only the head and neck was unearthed in 1965 by Polish and Mongolian scientists, making Opisthocoelicaudia one of the best known sauropods from the Late Cretaceous. Tooth marks on this skeleton indicate that large carnivorous dinosaurs had fed on the carcass and possibly had carried away the now-missing parts. To date, only two additional, much less complete specimens are known, includin

Conchoraptor (meaning "conch plunderer") is a genus of oviraptorid dinosaurs that lived in Asia during the Late Cretaceous epoch, about 70 million years ago. It is known from the Barun Goyot and possibly the Nemegt formation of Mongolia.

Anserimimus ( ; "goose mimic") is a genus of ornithomimid theropod dinosaur, from the Late Cretaceous Period of what is now Mongolia. It was a lanky, fast-running animal, possibly an omnivore. From what fossils are known, it probably closely resembled other ornithomimids, except for its more powerful forelimbs.

Barsboldia (meaning "of Barsbold", a well-known Mongolian paleontologist) is a genus of large hadrosaurid dinosaur from the Maastrichtian Nemegt Formation of Ömnogöv, Mongolia. It is known from a partial vertebral column, partial pelvis, and some ribs.

Elmisaurus (meaning "foot sole lizard") is an extinct genus of caenagnathid theropod dinosaur from the Late Cretaceous Nemegt Formation of Mongolia.

Borogovia is a troodontid theropod dinosaur genus which lived during the Late Cretaceous Period, in what is now Mongolia. It contains one species, Borogovia gracilicrus.

Rinchenia (named after Byambyn Rinchen) is a genus of oviraptorid dinosaur that lived in Asia during the Late Cretaceous epoch in what is now Mongolia, Nemegt Formation. The type and only known species, Rinchenia mongoliensis, was originally classified as a species within the genus Oviraptor (named Oviraptor mongoliensis), but a subsequent reexamination found differences significant enough to warrant a separate genus. The name Rinchenia was coined for this new genus, though not formally described in detail.

Nemegtomaia is a genus of oviraptorid dinosaur from what is now Mongolia that lived in the Late Cretaceous Period, about 72 to 70million years ago. The first specimen was found in 1996, and became the basis of the new genus and species N. barsboldi in 2004. The original genus name was Nemegtia, but this was changed to Nemegtomaia in 2005, as the former name was preoccupied. The first part of the generic name refers to the Nemegt Basin, where the animal was found, and the second part means "good mother", in reference to the fact that oviraptorids are known to have brooded their eggs. The specif

Nomingia is a genus of oviraptorosaurian theropod dinosaur known from the Late Cretaceous Bugin Tsav Beds of Mongolia.

Bagaraatan (/'ba-ɣa-raa-tan/ meaning 'small' baɣa + 'carnivorous animal, beast of prey' araatan in Mongolian) is a genus of theropod dinosaur from the Late Cretaceous period of what is now the Nemegt Formation of Mongolia. It may have been a small predatory dinosaur measuring around in length.

Gobiraptor is a genus of oviraptorid maniraptoran dinosaur from the Maastrichtian-aged Nemegt Formation of Mongolia. The type and only species is Gobiraptor minutus, known from a single incomplete specimen—the holotype MPC-D 102/111. It has been found not to be closely related to the other oviraptorids it shared its environment with.

Tochisaurus (meaning "Ostrich lizard") is a genus of small troodontid theropod dinosaur from the Late Cretaceous Period of Mongolia. The type (and only named) species is Tochisaurus nemegtensis.

Brodavis is a genus of freshwater hesperornithiform birds known from the Late Cretaceous (possibly Campanian and Maastrichtian stage) of North America and Asia. It was first described and named by Larry D. Martin, Evgeny N. Kurochkin and Tim T. Tokaryk in 2012 and assigned to a new monogeneric family, Brodavidae. Four species were described and assigned to Brodavis.

Nemegtonykus (meaning "Nemegt claw") is a genus of alvarezsaurid dinosaur from the Late Cretaceous ( Maastrichtian) Nemegt Formation of Mongolia. The type and only species is Nemegtonykus citus. It is the second alvarezsaurid known from the Nemegt Formation, preceded by Mononykus.

Manipulonyx is an extinct genus of alvarezsaurid theropod dinosaurs known from the Late Cretaceous (Maastrichtian age) Nemegt Formation of Mongolia. The genus contains a single species, Manipulonyx reshetovi, known from a partial skeleton. This includes the most complete forelimb known from any member of the alvarezsaurid subfamily Parvicursorinae, including all of the proximal bones. Manipulonyx has been interpreted as an ovivore (egg-eater), with unique ossified spikes on the wrist that helped the animal to grasp eggs and an enlarged claw on the functionally-monodactyl hand being used to pun
