List of Asian dinosaurs facts for kids

This is a list of dinosaurs whose bones and other remains have been found in Asia. We're not including India here, because it was a separate landmass for most of the Mesozoic Era, which is often called the "Age of Dinosaurs." (If you want to learn about dinosaurs from India, check out the List of Indian and Madagascan Dinosaurs). This list also doesn't include birds, even though they are modern-day dinosaurs, because they lived after the Mesozoic Era.

How Dinosaurs Make It Onto This List

To be included here, a dinosaur must meet a few simple rules:

• The dinosaur's name must be officially recognized on the main list of dinosaur types.
• At least one type of this dinosaur must have been found in Asia.
• This list works with the main category for Asian dinosaurs from the Mesozoic Era.

Dinosaur Names Still Being Figured Out

Sometimes, scientists find fossils that are hard to classify, or they give a dinosaur a name that isn't officially recognized yet. Here are some of those:

• 

  Amtosaurus

• 

  Chienkosaurus

• 

  EK troodontid

• 

  Epidendrosaurus

• 

  "Eugongbusaurus"

• 

  "Gadolosaurus"

• 

  Gobiceratops

• 

  Gyposaurus

• 

  Lukousaurus

• 

  Magnirostris

• 

  Nomingia

• 

  Nurosaurus

• 

  Raptorex

• 

  "Ronaldoraptor"

• 

  "Sinopliosaurus" fusuiensis

• 

  Zhongyuansaurus

• Amtosaurus magnus: This dinosaur is an ornithischian, but we're not sure if it's a hadrosaurid or an ankylosaurid.
• Antarctosaurus: A species from Kazakhstan was linked to this genus, but that's probably incorrect.
• Asiamericana asiatica: Only known from teeth. It might be a fish, a spinosaurid, or a type of Richardoestesia.
• "Bakesaurus": Often listed as a dinosaur name that was never officially published (nomen nudum). It might just be a misspelling of Bactrosaurus.
• "Balochisaurus malkani": A supposed saltasaurid titanosaur from Pakistan. New research might make this name, and others from Pakistan, official.
• Beipiaognathus jii: Its main fossil is a mix of bones from different animals, including a compsognathid.
• "Changdusaurus laminoplacodus": A possible stegosaur whose remains are now thought to be lost.
• Chienkosaurus ceratosauroides: It might be the same as Szechuanosaurus.
• "Dachongosaurus yunnanensis": Reported to be a sauropod similar to Cetiosaurus.
• "Damalasaurus": A sauropod whose exact type is unknown. Two species have been named, but not officially.
• "EK troodontid": This is the informal name for a troodontid fossil found in Early Cretaceous rocks in Mongolia.
• Epidendrosaurus ninchengensis: Most scientists agree it's the same as Scansoriopteryx. There's a debate about which name should be used.
• "Eugongbusaurus" wucaiwanensis: This name was created for a species once linked to Gongbusaurus. It's said to have been leaked by accident.
• "Futabasaurus": A supposed tyrannosaur from Japan. If officially described, it would need a new name because Futabasaurus is already used for a plesiosaur.
• "Gadolosaurus": This name was a mistake, a wrong spelling of the Russian word for hadrosaur. It was not meant to be a new dinosaur name. It might have been the same as Arstanosaurus.
• Gobiceratops minutus: It might be a younger version of Bagaceratops.
• "Gspsaurus pakistani": One of several titanosaurs from Pakistan that haven't been officially named.
• Gyposaurus: The main species was found in South Africa and might be the same as Massospondylus. The Asian species might be identical to Lufengosaurus.
• "Hanwulosaurus": Possibly the most complete ankylosaur found in Asia. It's said to belong to its own special group within ankylosaurs.
• "Heilongjiangosaurus jiayinensis": It might be the same as Charonosaurus and/or "Mandschurosaurus" jiayinensis.
• "Khetranisaurus barkhani": Also spelled "Khateranisaurus." Both spellings are still informal.
• "Koreanosaurus": This has no connection to the officially named ornithischian of the same name (listed above). It was later renamed "Deinonychus" "koreanensis," but this is likely incorrect.
• "Kunmingosaurus wudingensis": Although sometimes shown as a valid dinosaur, it's actually a name that was never officially published (nomen nudum).
• Lamaceratops tereschenkoi: It might be the same as Bagaceratops.
• "Lancanjiangosaurus cachuensis": A sauropod that hasn't been officially named. It's also been spelled "Lancangosaurus."
• Lukousaurus yini: Sometimes thought to be either a theropod or a type of ancient crocodile.
• Magnirostris dodsoni: It was supposedly different from other early ceratopsians because of its small horn cores, but it might actually be a Bagaceratops with a fossilization quirk.
• "Marisaurus jeffi": Potentially closely related to "Balochisaurus" and "Sulaimanisaurus".
• "Megacervixosaurus tibetensis": A sauropod whose classification is uncertain, but it might be a titanosaur.
• "Microdontosaurus dayensis": It might have been officially described under a different name, but this can't be proven.
• "Ngexisaurus dapukaensis": Sometimes known as Megalosaurus "dapukaensis," but it's unlikely to belong to that genus.
• Nomingia gobiensis: Important as one of the first non-avian dinosaurs found with a pygostyle (fused tail bones). However, it might be the same as Elmisaurus.
• "Nurosaurus qaganensis": Noted for having the first stress fracture found on a sauropod foot. It was said to be "soon to be described" in 1992 but is still an unofficial name.
• "Oshanosaurus youngi": An early sauropod. It has been confused with heterodontosaurids and Eshanosaurus.
• "Otogosaurus sarulai": Very little is known about it. Although it often appears on dinosaur lists, there's no proof it was ever officially named.
• "Pakisaurus balochistani": A titanosaur. It has been linked to the unofficial titanosaur family "Pakisauridae."
• Platyceratops tatarinovi: It might be the same as Bagaceratops.
• Raptorex kriegsteini: Described as a small adult tyrannosaur from early Cretaceous China. However, new studies suggest it was from late Cretaceous Mongolia, and likely a young Tarbosaurus.
• "Ronaldoraptor": An oviraptorosaur with a tall, rectangular crest. It was named in a book described as a field guide for time travelers.
• "Sanchusaurus": Said to be potentially the same as Gallimimus.
• "Sangonghesaurus": Possibly the same as Tianchisaurus, if it's not a primitive ornithischian.
• Shuangbaisaurus anlongbaoensis: It might be a variation of Sinosaurus.
• "Sinopliosaurus" fusuiensis: Originally thought to be a plesiosaur, but it's actually a spinosaurid. It might be the same as Siamosaurus.
• "Sugiyamasaurus": Known only from teeth that might belong to Fukuititan.
• "Sulaimanisaurus gingerichi": An unofficial titanosaur from Pakistan.
• "Szechuanoraptor dongi": This name was created for a fossil once linked to Szechuanosaurus. It might belong to Yangchuanosaurus zigongensis.
• "Tonouchisaurus mongoliensis": A theropod reported to have only two fingers on its hand.
• "Vitakridrinda sulaimani": Supposedly an abelisaurid. It's sometimes treated as valid in books, like one by Thomas Holtz.
• "Vitakrisaurus saraiki": A noasaurid found in the same rock layers as "Vitakridrinda".
• "Yibinosaurus zhoui": It might actually be a second species of Gongxianosaurus.
• "Yunxianosaurus hubeinensis": Mentioned in a scientific paper as a temporary name. More study is needed to see if it deserves an official name.
• Zhongornis haoae: Known from a young skeleton. It's usually thought to be a primitive bird, but one idea is that it's a non-avian scansoriopterygid.
• Zhongyuansaurus luoyangensis: It might be the same as Gobisaurus.
