Maiasaura
Maiasaura (from , and , the feminine form of saurus, ) is a large herbivorous saurolophine hadrosaurid ("duck-billed") dinosaur genus that lived in the area currently covered by the state of Montana and the Canadian province of Alberta, in the Upper Cretaceous (mid to late Campanian), from 86.3 to 70.6 million years ago. Maiasaura is the state fossil of Montana.
Torvosaurus
Torvosaurus () is a genus of large megalosaurine theropod dinosaur that lived approximately 165 to 146.5 million years ago during the Callovian to Tithonian ages of the late Middle and Late Jurassic period in what is now Colorado, Portugal, Germany, and possibly England, Spain, Tanzania, and Uruguay. It contains two currently recognized species, Torvosaurus tanneri and Torvosaurus gurneyi, plus a third unnamed species from Germany.
Segnosaurus
Segnosaurus is a genus of therizinosaurid dinosaur that lived in what is now southeastern Mongolia during the Late Cretaceous, about 102–86 million years ago. Multiple incomplete but well-preserved specimens were discovered in the Gobi Desert in the 1970s, and in 1979 the genus and species Segnosaurus galbinensis were named. The generic name Segnosaurus means "slow lizard" and the specific name galbinensis refers to the Galbin region. The known material of this dinosaur includes the lower jaw, neck and tail vertebrae, the pelvis, shoulder girdle, and limb bones. Parts of the specimens hav

Piatnitzkysaurus
Piatnitzkysaurus ( ; meaning "Piatnitzky's lizard") is a genus of tetanuran theropod dinosaur that lived approximately 179 to 177 million years ago during the lower part of the Jurassic Period in what is now Argentina. Piatnitzkysaurus was a moderately large, lightly built, bipedal, ground-dwelling carnivore that could grow over long.

Mussaurdes
Mussaurus (meaning "mouse lizard") is a genus of herbivorous sauropodomorph dinosaur that lived in southern Argentina during the Sinemurian stage of the Early Jurassic. It receives its name from the small size of the skeletons of juvenile and infant individuals, which were once the only known specimens of the genus. However, since Mussaurus is now known from adult specimens, the name is something of a misnomer.

Miracinonyx
Miracinonyx, colloquially known as the American cheetah or the New World cheetah, is an extinct genus of felids belonging to the subfamily Felinae that was endemic to North America from the Pleistocene epoch (about 2.5 million to 16,000 years ago) and morphologically similar to the modern cheetah (Acinonyx jubatus), although its apparent similar ecological niches have been considered questionable due to anatomical morphologies of the former that would have limited its ability to act as a specialized pursuit predator. The genus was originally known from fragments of skeletons, but nearly comple

Patagosaurus
Patagosaurus (meaning "Patagonia lizard") is an extinct genus of eusauropod dinosaur from the middle Toarcian of Patagonia, Argentina. It was first found in deposits of the Cañadón Asfalto Formation, which date to around 178 million years ago. Although originally twelve specimens were assigned to the taxon, at least one of them may belong to a different genus. Patagosaurus probably lived alongside genera such as Piatnitzkysaurus, Condorraptor, and Volkheimeria.

Nanshiungosaurus
Nanshiungosaurus (meaning "Nanxiong's lizard") is a genus of therizinosaurid that lived in what is now Asia during the Late Cretaceous of South China. The type species, Nanshiungosaurus brevispinus, was first discovered in 1974 and described in 1979 by Dong Zhiming. It is represented by a single specimen preserving most of the cervical and dorsal vertebrae with the pelvis. A supposed and unlikely second species, "Nanshiungosaurus" bohlini, was found in 1992 and described in 1997. It is also represented by vertebrae but this species however, differs in geological age and lacks authentic charact

Gilmoreosaurus
Gilmoreosaurus (meaning "Charles Whitney Gilmore's lizard") is a genus of hadrosauromorphan dinosaur from the Late Cretaceous of Asia. The type species is Gilmoreosaurus mongoliensis, known from the Iren Dabasu Formation of Inner Mongolia, dating to 96 million years ago. Additional specimens have been described as distinct species, including G. atavus from the Khodzhakul Formation of Uzbekistan, and G. arkhangelskyi from the Bissekty Formation, also of Uzbekistan. However, these are based on very fragmentary remains, and their classification is dubious. An additional species, G. kysylkumense,

Dravidosaurus
Dravidosaurus ("Dravidian lizard") is a dubious genus of Late Cretaceous reptiles, variously interpreted as either a ornithischian (possibly a stegosaurian) dinosaur or a plesiosaur. The genus contains a single species, D. blanfordi, known from mostly poorly preserved fossils from the Coniacian (Late Cretaceous) of southern India.
Pachyrhachis
Pachyrhachis (from , 'thick' and , 'spine') is an extinct genus of snake with well developed hind legs known from fossils discovered in Ein Yabrud, near Ramallah, in the central West Bank. It is a relatively small snake, measuring more than long at maximum. Pachyrhachis appears to have been an ancient marine snake; the fossils occur in a marine limestone deposit, and the thickened bone of the ribs and vertebrae would have functioned as ballast to decrease the buoyancy of the animal, allowing it to dive beneath the ancient Cretaceous seas that it once inhabited.

Secernosaurus
Secernosaurus (meaning "severed lizard") is a genus of herbivorous hadrosaurid dinosaur that lived during the Late Cretaceous of what is now Argentina. This genus and its close relatives lived in South America, unlike most hadrosaurids, which lived in the Laurasian continents of Eurasia and North America. It has been suggested that the ancestors of Secernosaurus crossed into South America when a land bridge temporarily formed between North and South America during the Late Cretaceous and allowed biotic interchange between the two continents.
Unquillosaurus
Unquillosaurus (meaning "Unquillo river lizard") is a genus of large theropod dinosaur from the Late Cretaceous Los Blanquitos Formation of Salta Province, Argentina. Its precise classification is uncertain, but most researchers consider it as a maniraptoran. The genus contains a single species, U. ceibalii, known only from a single fossilized pubis (a pelvic bone).
Gravitholus
Gravitholus (meaning 'heavy dome') was a genus of pachycephalosaurid dinosaur from the late Cretaceous period (Campanian stage, around 75 million years ago). It was a pachycephalosaur, and like other pachycephalosaurids the skull roof formed a thick dome made of dense bone, which may have been used in head-butting contests over mates or territory. It lived in what is now Alberta, Canada, and was described in 1979 by W. P. Wall and Peter Galton. The type species is Gravitholus albertae.

Yandusaurus
Yandusaurus is a genus of basal neornithischian dinosaur from the middle Jurassic (Bathonian age, approximately 168 to 162 Ma) of eastern Asia. The type species is Y. hongheensis, described in 1979 from the Lower Shaximiao Formation of Sichuan Province, China.

Drepanosaurus
Drepanosaurus (; "sickle lizard") is a genus of arboreal (tree-dwelling) reptile that lived during the Triassic Period. It is a member of the Drepanosauridae, a group of diapsid reptiles known for their prehensile tails. Drepanosaurus was probably an insectivore, and lived in a coastal environment in what is now modern day Italy, as well as in a streamside environment in the southwestern United States.
Volkheimeria
Volkheimeria is an extinct genus of sauropod dinosaurs that lived in what is now Argentina during the Early Jurassic, about 179–178 million years ago. Its type and only species is Volkheimeria chubutensis.
Burgessochaeta
Burgessochaeta is an extinct genus of polychaete annelids from the Middle Cambrian. Its fossils have been found in the Burgess Shale in British Columbia, Canada. The genus was described by Conway Morris (1979) and re-examined by Eibye-Jacobsen (2004).
Ernanodon
Ernanodon ("a sprout of toothless animals") is an extinct genus of placental mammal from extinct family Ernanodontidae within extinct order Palaeanodonta, that lived from the middle to late Paleocene in China (Nongshan Formation) and Mongolia.
Megaoryzomys
Megaoryzomys curioi, also known as the Galápagos giant rat, is an extinct species of sigmodontine rodent, known only from Santa Cruz Island in the Galápagos Islands. It likely met its demise when European settlers introduced invasive species to the island. It is the only species in the genus Megaoryzomys. Its relationships have historically been unclear; it has been placed in both Oryzomyini and Thomasomyini in the past. A 2021 study favoured placing it in the former on overall skull morphology.
Barawertornis tedfordi
Barawertornis is an extinct genus of cassowary-sized dromornithid known from Oligocene and Miocene deposits in Queensland and South Australia. Only a single species, B. tedfordi, is placed in this genus. It shows adaptations towards a cursorial lifestyle. Like other dromornithids, Barawertornis was probably a folivorous and frugivorous browser.
Tylocephalonyx
Tylocephalonyx, from Ancient Greek (túlos), meaning "knob", (képhalos), meaning "head", and (ónux), meaning "claw/hoof", is an extinct schizotherine chalicothere from the Miocene of North America.
Microhadrosaurus
Microhadrosaurus (meaning "small bulky lizard" in Greek) is a genus of hadrosaurid dinosaur from the Late Cretaceous (Campanian or Maastrichtian) Nanxiong Formation of Guangdong, China. Although its name identifies it as a small hadrosaurid, it is based on juvenile remains, and the adult size is unknown.
Arganodus
Arganodus is an extinct genus of freshwater lungfish that had a wide global distribution throughout much of the Triassic period, with a single species surviving across Gondwana into the Cretaceous. It is the only member of the family Arganodontidae, although it is sometimes placed in the Ceratodontidae or synonymized with the genus Asiatoceratodus.
Protoichthyosaurus
Protoichthyosaurus is a genus of ichthyosaur from the early Jurassic of southern England and possibly Switzerland. Two species are known, P. prostaxalis—the type species, named by Appleby in 1979—and P. applebyi. A third species, P. prosostealis, was named by Appleby, but it was removed from the genus in 2017 due to its similarity to Ichthyosaurus. The genus Protoichthyosaurus was synonymized with Ichthyosaurus by Maisch and Hungerbuhler in 1997, and again by Maisch and Matzke in 2000. However, it was found to be distinct in 2017 by Dean Lomax and colleagues, who separated it from Ichthyosauru
Hainina
Hainina is an extinct mammal genus from the latest Cretaceous to the Paleocene of Europe.
Alforjas
Alforjas is an extinct genus of camelid, endemic to North America. They lived during the Late Miocene 10.3—5.3 mya existing for approximately .

Kalisuchus
Kalisuchus ('Kali's crocodile') was a genus of basal archosauriform known from remains unearthed from the Arcadia Formation (Rewan Group) of the Early Triassic of the Crater, Southwest of Rolleston, south central Queensland, Australia. It was named after Kali, the Hindu goddess of destruction, a reference to the very fragmentary nature of its remains. The type species of Kalisuchus is K. rewanensis, which refers to the Rewan Group. The Arcadia formation is dated to the Induan age at the very beginning of the Triassic, making Kalisuchus one of the oldest archosauromorphs known in Australia.
Odontocyclops
Odontocyclops (Greek: “tooth” Greek: “round eye”, a kind of Greek mythological giant with one eye in the midline; "toothy cyclops") is an extinct genus of Dicynodonts that lived in the Late Permian. Dicynodonts are believed to be the first major assemblage of terrestrial herbivores.
Fossils of Odontocyclops have been found in the Karoo Basin of South Africa and the Luangwa Valley of Zambia. The phylogenetic classification of Odontocyclops has been long under debate, but most current research places them as their own genus of Dicynodonts and being very closely related to Rhachiocephalus and Oud
