Deinocheirus
Deinocheirus (ˌdaɪnoʊ-ˈkaɪrəs ) 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.
Beishanlong
Beishanlong is a genus of giant ornithomimosaurian theropod dinosaur from the Early Cretaceous of China. It is the second-largest ornithomimosaur discovered, only surpassed by Deinocheirus. Three fossils of Beishanlong were in the early twenty-first century found in northwestern China at the White Ghost Castle site, in the province of Gansu. The type species is Beishanlong grandis, described and named online in 2009 by a team of Chinese and American paleontologists, and formally published in January 2010 by the same Peter Makovicky, Li Daiqing, Gao Keqin, Matthew Lewin, Gregory Erickson and Mark Norrell.
Garudimimus
Garudimimus (meaning "Garuda mimic") is a genus of ornithomimosaur that lived in Asia during the Late Cretaceous. The genus is known from a single specimen found in 1981 by a Soviet-Mongolian paleontological expedition in the Bayan Shireh Formation and formally described in the same year by Rinchen Barsbold; the only species is Garudimimus brevipes. Several interpretations about the anatomical traits of Garudimimus were made in posterior examinations of the specimen, but most of them were criticized during its comprehensive redescription in 2005.
Paraxenisaurus
Paraxenisaurus (meaning "strange lizard") is a genus of deinocheirid theropod dinosaur that lived in what is now Mexico during the Campanian stage of the Late Cretaceous Period, 73 to 72.1 million years ago. During the 1990s, ornithomimosaur fossils were discovered at three sites in the Cerro del Pueblo Formation of Coahuila state. Two decades later, these remains were identified as belonging to a distinct North American taxon.

Anserimimus
Anserimimus (ˌænsərᵻˈmaɪməs ; "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. Anserimimus was found in the Mongolian aimag, or province, of Bayankhongor during a joint Soviet-Mongolian expedition to the Gobi Desert, in the late 1970s.
Gallimimus
Gallimimus (ˌɡælᵻˈmaɪməs ) is a genus of theropod dinosaur that lived in what is now Mongolia during the Late Cretaceous period, about seventy million years ago (mya). 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.
