Achillobator ( ; meaning "Achilles hero") is a genus of large dromaeosaurid theropod dinosaur that lived during the Late Cretaceous period about 96 million to 89 million years ago in what is now the Bayan Shireh Formation of Mongolia. The genus is currently monotypic, only including the type species A. giganticus. The first remains were found in 1989 during a Mongolian-Russian field expedition and later described in 1999. Remains at the type locality of Achillobator may represent additional specimens. It represents the first and largest dromaeosaurid known from the Bayan Shireh Formation.

Caudipteryx (meaning "tail feather") is a genus of small oviraptorosaurian dinosaurs that lived in China during the Early Cretaceous, around 124.6 million years ago. They were feathered and extremely bird-like in their overall appearance, to the point that some paleontologists suggested it was a bird. Two species have been described: C. zoui (the type species), in 1998, and C. dongi, in 2000. Caudipteryx had a stout trunk, long legs, and was probably a swift runner. Its discovery has led to many intensive studies and debate over the relationship between birds and dinosaurs.

Shuvuuia is a genus of bird-like theropod dinosaur from the late Cretaceous period of Mongolia. It is a member of the family Alvarezsauridae, small coelurosaurian dinosaurs which are characterized by short but powerful forelimbs specialized for digging. The type (and only known) species is Shuvuuia deserti, or "desert bird". The name Shuvuuia is derived from the Mongolian word shuvuu (шувуу) meaning "bird".

Citipati (; meaning "funeral pyre lord") is a genus of oviraptorid dinosaur that lived in Asia during the Late Cretaceous period, about 75 million to 71 million years ago. It is mainly known from the Ukhaa Tolgod locality at the Djadochta Formation, where the first remains were collected during the 1990s. The genus and type species Citipati osmolskae were named and described in 2001. A second species from the adjacent Zamyn Khondt locality may also exist. Citipati is one of the best-known oviraptorids thanks to a number of well-preserved specimens, including individuals found in brooding posit

Guanlong () is an extinct genus of proceratosaurid tyrannosauroid dinosaur from the Late Jurassic (Oxfordian) Shishugou Formation of China. It was first described in 2006 by Xu Xing and colleagues, who found it to represent a new taxon related to Tyrannosaurus. Two individuals are currently known, consisting of a partially complete adult and a nearly complete juvenile.

Huaxiagnathus is an extinct genus of coelurosaurian theropod dinosaur from the Lower Cretaceous of China. The genus contains a single species, Huaxiagnathus orientalis, known from two immature individuals from the Yixian Formation. Huaxiagnathus may represent an earlier ontogenetic stage of the tyrannosauroid Sinotyrannus from the younger Jiufotang Formation.

Anchiornis is a genus of small, four-winged paravian dinosaurs, with only one known species, the type species Anchiornis huxleyi, named for its similarity to modern birds. The Latin name Anchiornis derives from a Greek word meaning "near bird", and huxleyi refers to Thomas Henry Huxley, a contemporary of Charles Darwin. Anchiornis fossils have been found only in the Tiaojishan Formation of Liaoning, China, in rocks dated to the Late Jurassic, about 160 million years ago. It is known from hundreds of specimens, and given the exquisite preservation of some of these fossils, it became the first M

Sinovenator (meaning "Chinese hunter") is a genus of troodontid dinosaur from China. It is from the early Cretaceous Period.

Xiongguanlong (International Phonetic Alphabet|) is an extinct genus of tyrannosauroid theropod from the Early Cretaceous period of what is now China. The type and only species is X. baimoensis. The generic name comes from Jiayuguan City (formerly called "Xiong Guan" or "grand pass") and the Mandarin word "long" which means dragon. The specific epithet, "baimoensis" is a latinization of the Mandarin word for "white ghost" in reference to one of the geological features of the type locality (nicknamed the "White Ghost Castle").

Liaoceratops, meaning "Liaoning horned face", is a ceratopsian dinosaur believed to be an early relative of the horned ceratopsids. It lived in the Early Cretaceous, 126 million years ago. It was discovered in China by a team of American and Chinese scientists. Liaoceratops was much smaller than its later relatives, but offers a glimpse into the early evolution of this group of dinosaurs. ==Discoveries and naming== left|thumb|Skeletal restoration Liaoceratops was discovered in the famous Liaoning Province of China, where several fossils of feathered dinosaurs have also been collected. The type

Sciurumimus ("squirrel mimic," named for its tail's resemblance to that of the tree squirrel genus Sciurus) is an extinct genus of tetanuran theropod from the Late Jurassic Torleite Formation of Germany. It is known from a single juvenile specimen representing the type species, Sciurumimus albersdoerferi, which was found in a limestone quarry close to Painten in Lower Bavaria. The specimen was preserved with traces of feather-like filaments.

Khaan (; from Mongol 'lord') is an extinct genus of oviraptorid dinosaur known from remains found in the Djadochta Formation of Mongolia, dating to the Late Cretaceous (Campanian, 75-71 million years ago).

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 the related Deinocheirus.

Shenzhousaurus (meaning "Shenzhou lizard") is a genus of basal ornithomimosaurian theropod dinosaur from the Lower Cretaceous of China.left|thumb|RestorationThe holotype (NGMC 97–4–002, National Geological Museum of China) was collected from near the bottom (fluvial beds) of the Yixian Formation (Aptian) at the Sihetun fossil site, Beipiao, western Liaoning Province. This specimen consists of a partial skeleton preserved on a sandstone slab in a "death pose," its head above the torso. The distal parts of the hindlimbs, distal portion of the tail, and the forelimbs (except for part of the right

Aorun () (敖闰 pinyin Áo rùn) is a genus of carnivorous theropod dinosaur first discovered in 2006, with its scientific description published in 2013. It is generally considered one of the oldest known coelurosaurian dinosaurs and is estimated to have lived ~161.6 million years ago during the Late Jurassic Period, though some researchers consider it to be a carnosaurian instead.

Albinykus (meaning "Albin claw", after a term used by Mongolian shamans to describe light phenomena in the Gobi Desert) is a genus of alvarezsaurid dinosaur whose fossils have been found in the Late Cretaceous-aged (Santonian) Javkhlant Formation in the Gobi Desert of Mongolia. The type species, A. baatar, was named by Sterling J. Nesbitt, Julia A. Clarke, Alan H. Turner and Mark A. Norell in 2011.

Erketu (meaning "Erketü tengri") is a genus of somphospondylan dinosaur that lived in Asia during the Late Cretaceous, roughly between 96 million and 89 million years ago. It is known from the Bayanshiree Formation of Mongolia, and its fossils were found between 2002 and 2003 during field expeditions. Erketu was first described in 2006 and later on in 2010 due to some cervicals that were left behind in the expedition. This genus represents the first sauropod described from the Bayanshiree Formation. The elongated cervical vertebrae indicate that it probably had the longest neck relative to its

Apsaravis is a Mesozoic avialan genus from the Late Cretaceous. The single known species, Apsaravis ukhaana, lived about 78 million years ago, in the Campanian age of the Cretaceous period. Its fossilized remains were found in the Camel's Humps sublocality of the Djadokhta Formation, at Ukhaa Tolgod in the Gobi Desert of Mongolia. They were collected in the 1998 field season by the Mongolian Academy of Sciences/American Museum of Natural History Paleontological Expeditions. It was described by Norell and Clarke (2001).

Armandisaurus explorator is an extinct species of iguanid that lived in what is now Santa Fe County, New Mexico, in the Early Middle Miocene period. The fossil specimen is a well-preserved cranium with mandibles and parts of seven cervical vertebrae collected by J. C. Blick in 1940. Fossil evidence suggests that A. explorator was a blunt, medium-sized iguana that grew to about 61 cm (24 in) including its tail.
