Dryosaurus (/ ˌ d r aɪ ə ˈ s ɔːr ə s / DRY-ə-SOR-əs, meaning 'tree lizard', Greek δρῦς (drys) meaning 'tree, oak' and σαυρος (sauros) meaning 'lizard'; the name reflects the forested habitat, not a vague oak-leaf shape of its cheek teeth as is sometimes assumed) is a genus of an ornithopod dinosaur that lived in the Late Jurassic period.
The closest is the Dinosaur Genera List, compiled by biological nomenclature expert George Olshevsky, which was first published online in 1995 and was regularly updated until June 2021. [ 1 ] [ 2 ] The most authoritative general source in the field is the second (2004) edition of The Dinosauria .
Yutyrannus (Simplified Chinese : 华丽羽王龙 Traditional Chinese : 華麗羽王龍 Pinyin : Huà Lì Yǔ Wáng Lóng meaning "feathered tyrant") is a genus of proceratosaurid tyrannosauroid dinosaur which contains a single known species, Yutyrannus huali. This species lived during the early Cretaceous period in what is now northeastern ...
Dinosaurs belong to a group known as archosaurs, which also includes modern crocodilians. Within the archosaur group, dinosaurs are differentiated most noticeably by their gait. Dinosaur legs extend directly beneath the body, whereas the legs of lizards and crocodilians sprawl out to either side. [29]
Yi is a genus of scansoriopterygid dinosaur from the Late Jurassic of China.Its only species, Yi qi (Mandarin pronunciation: [î tɕʰǐ]; from Chinese: 翼; pinyin: yì; lit.

It had large eyes as shown by the curved jugal.The teeth, showing a unique pattern of parallel vertical ridges compared by Chinese researchers to the fingers of the hand of Buddha statues, are very asymmetrical in that the inner side is strongly worn down.
Yuxisaurus was a basal thyreophoran. Depending on the dataset, it may be the sister taxon to the German Emausaurus or more basal than Scelidosaurus and eurypods.The discovery of Yuxisaurus definitively proves that thyreophorans were present in Asia during the Early Jurassic, as other potential records of Early Jurassic Asian thyreophorans, Bienosaurus and Tatisaurus, are too fragmentary to be ...
