Mounted skeletons of Tyrannosaurus (left) and Apatosaurus (right) at the AMNH. Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research.
There is no complete, canonical list of all dinosaur taxa or holotype specimens. Attempts are regularly published in the form of books, such as the Princeton Field Guide to Dinosaurs by Gregory Paul [8] and Dinosaurs: The Most Complete, Up-to-Date Encyclopedia for Dinosaur Lovers of All Ages by Thomas Holtz and Luis Rey.

Jintasaurus (Chinese: 金塔龙; pinyin: Jīntǎ lóng; meaning "Jinta County dragon") is a genus of hadrosauriform dinosaur described by Hai-Lu You (尤海鲁, Yóu Hǎilǔ) and Da-Qing Li (李大庆, Lǐ Dàqìng) in 2009. The type species is J. meniscus. Jintasaurus lived during the Early Cretaceous of what is now Gansu, northwestern China.
"Bayosaurus" is the informal name given to an as yet undescribed genus of theropod dinosaur. The name was coined by paleontologists Rodolfo Coria, Philip J. Currie, and Paulina Carabajal in 2006. It apparently was an abelisauroid from the Turonian Cerro Lisandro Formation of Neuquén, Argentina, around 4 m (13 ft) long.
This list of nicknamed dinosaur fossils is a list of fossil non-avian dinosaur specimens given informal names or nicknames, in addition to their institutional catalogue numbers. It excludes informal appellations that are purely descriptive (e.g., "the Fighting Dinosaurs", "the Trachodon Mummy").
Jaxartosaurus (meaning "Jaxartes lizard" after the early name of the Syr Darya) is a genus of hadrosaurid dinosaur similar to Corythosaurus which lived during the Late Cretaceous. Its fossils were found in Kazakhstan .
Dinosaur classification began in 1842 when Sir Richard Owen placed Iguanodon, Megalosaurus, and Hylaeosaurus in "a distinct tribe or suborder of Saurian Reptiles, for which I would propose the name of Dinosauria." [1] In 1887 and 1888 Harry Seeley divided dinosaurs into the two orders Saurischia and Ornithischia, based on their hip structure. [2]
Jainosaurus is a genus of titanosaurian sauropod dinosaur of India and wider Asia, which lived in the Maastrichtian (approximately 68 million years ago).It is thought to have been about the same size as its contemporary relative Isisaurus, measuring 18 metres (59 ft) long and weighing 15 metric tons (17 short tons).
