Velociraptor is a genus of small dromaeosaurid dinosaurs that lived in Asia during the Late Cretaceous epoch, about 75 million to 71 million years ago. Two species are currently recognized, although others have been assigned in the past. The type species is V. mongoliensis, named and described in 1924. Fossils of this species have been discovered in the Djadochta Formation, Mongolia. A second species, V. osmolskae, was named in 2008 for skull material from the Bayan Mandahu Formation, China.
Morrisonodon brentbaatar is an extinct multituberculate mammal from the Upper Jurassic Morrison Formation of North America.
The Trachypachidae are a family of beetles that generally resemble small ground beetles, but that are distinguished by the large coxae of their rearmost legs. There are only six known extant species in the family, with four species of Trachypachus found in northern Eurasia and northern North America, and two species of Systolosoma in Chile and Argentina. They were much more diverse in the past, with dozens of described species from the Mesozoic.
Scarabaeoidea is a superfamily of beetles, the only subgroup of the infraorder Scarabaeiformia. Around 35,000 species are placed in this superfamily and some 200 new species are described each year. Its constituent families are also undergoing revision presently, and the family list below is only preliminary. This superfamily includes some of the largest beetles extant today, including rhinoceros beetles, (Dynastinae), the Hercules beetle and Goliath beetles.
Zosuchus is a genus of basal, Late Cretaceous crocodyliform from Mongolia.
The Perissommatidae are a family of flies (Diptera) that was proposed in 1962 by Donald Colless based on the species Perissomma fusca from Australia. The family now includes five extant species within the single genus Perissomma, four from Australia and one from Chile. The Perissommatidae are unusual as they appear to have four compound eyes. They have a small slender body less than 2 mm in length. Their wings are large in comparison to their bodies and subsequently their flight is weak. Preferring high-altitude forest environments, adults only fly in the winter. The larvae live in decaying leaf litter in wet sclerophyll or cool rain forests. Some species are suspected to be associated with fungi. In the case of Perissomma macalpinei, numbers of adults have been observed congregating in clumps of foliage and rising in short, zigzag flights in the sunlight above the foliage for short periods before descending.
Pseudotribos is an extinct genus of mammaliaform that lived in Northern China during the Middle Jurassic some 165 million years ago, possibly more closely related to monotremes than to theria, although other studies indicate that these shuotheres are closer to therians than to monotremes. The only known specimen was found in the Daohugou Bed in Inner Mongolia.
Sinaspideretes is an extinct genus of turtle from the Late Jurassic of China, probably from the Shaximiao Formation. It is considered the earliest and most basal representative of the Trionychia, and is possibly the oldest known member of Cryptodira. In 2013, it was proposed that this animal and the genus Yehguia are in fact one and the same.
Protosuchia is a group of extinct Mesozoic crocodyliforms. They were small in size and terrestrial. In phylogenetic terms, Protosuchia is considered an informal group because it is a grade of basal crocodyliforms, not a true clade.
Gobiops is an extinct genus of temnospondyl from the Jurassic of Mongolia, China, and possibly Kyrgyzstan. The genus is represented by a single species, Gobiops desertus. It was named in 1991 from the Late Jurassic Shar Teeg Beds of Mongolia. Additional material was described in 2005 from the Middle Jurassic Toutunhe Formation in the Junggar Basin of China. Gobiops belongs to the family Brachyopidae. The poorly known genus Ferganobatrachus, named in 1990 from Shar Teeg, is probably synonymous with Gobiops.
Fruitachampsa is a genus of shartegosuchid crocodyliform from the Upper Jurassic Morrison Formation of Colorado. It is known from multiple specimens that show it to have been a relatively long-limbed terrestrial quadrupedal predator less than 1 metre (3.3 ft) long, with a short face and a prominent pair of canine-like teeth in the lower jaw. Before it was formally described in 2011, it was also known as the "Fruita form". Its type species is F. callisoni.
Shartegosuchus is a genus of protosuchian-grade crocodyliform. It is known primarily from PIN 4174/2, the partial deformed skull and jaws of a juvenile. This specimen was discovered in ancient lake deposits of the Tithonian-age Upper Jurassic Tsagaantsav Formation, southwestern Mongolia. The estimated length of the holotype skull is 40 millimetres (1.6 in). This genus was similar to Nominosuchus, and both are assigned to the same family (Shartegosuchidae). Shartegosuchus was described in 1988 by Mikhail Efimov, and the type species is S. asperopalatum.
The Tiaojishan Formation is a geological formation in Hebei and Liaoning, People's Republic of China, dating to the middle-late Jurassic period. It is known for its exceptionally preserved fossils, including those of plants, insects and vertebrates. It is made up mainly of pyroclastic rock interspersed with basic volcanic and sedimentary rocks. Previously, the Tiaojishan Formation was grouped together with the underlying Haifanggou Formation as a single "Lanqi Formation." The Tiaojishan Formation forms a key part of the Yanliao Biota assemblage, alongside the Haifanggou Formation.
Dorsetisaurus is a genus of extinct lizard, known from the Late Jurassic of North America, and the Late Jurassic-earliest Cretaceous of Europe. The genus was first reported from the Early Cretaceous (Berriasian) Lulworth Formation of the Purbeck Group of Durlston Bay, in Dorset. It has also been reported from the Late Jurassic aged Alcobaça Formation of Portugal, the Aptian-Albian Dzunbain Formation of Mongolia, and the Morrison Formation of Western North America present in stratigraphic zones 2, 4, and 5. It is considered the oldest widely accepted member of Anguimorpha. based on the presence of 11 shared synapomorphies.
The Ulan Malgait Formation is a Late Jurassic geologic formation in Mongolia. Dinosaur remains are among the fossils that have been recovered from the formation, although as of 2004 none have yet been referred to a specific genus.
Shantungosuchus is an extinct genus of Early Cretaceous crocodyliform found in China. It includes three species: Shantungosuchus chuhsienensis and S. brachycephalus, which were both described by Yang Zhongjian – usually referred to as "Young" – in 1961 and 1982, and S. hangjinensis, which was described by Xiao-Chun Wu et al in 1994. S. chuhsienensis is the type for this genus.
Platycrossos is an extinct genus of protocoleopteran beetles in the family Permosynidae. It is known from the Triassic and Jurassic of Australia, Austria, Mongolia and Russia. Like other members of the family, the species of this genus were described from fossils of isolated elytra with punctate striae.
Tegotherium is an extinct mammaliaform from the Late Jurassic of East Asia. The type species T. gubini is known from the Shar Teeg Beds of Mongolia and an indeterminate species is also known from the Late Jurassic Qigu Formation of China. It belongs to the clade Docodonta.
Shartegodon is an extinct genus of tritylodontid cynodont from late Jurassic Ulan Malgait Formation of Mongolia. The type species, Shartegodon altai, was named in 2017.
Nuurtherium is an extinct genus of tritylodontid cynodonts of the Late Jurassic Ulan Malgait Formation of Mongolia. It contains a single species, N. baruunensis, named by Paúl Velazco and colleagues in 2017.
