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 ...
Yinlong was a relatively small dinosaur, reaching 1.2 m (3.9 ft) in length and 10 kg (22 lb) in body mass. [3] Despite a virtually frill-less and totally hornless skull, Yinlong is a ceratopsian.

Protoceratops skeleton at the Wyoming Dinosaur Center. The classical folklorist Adrienne Mayor has proposed that the profusion of literary descriptions and imagery of the griffin in Greek and Roman literature and art beginning in the 7th century BC to the 3rd century AD were influenced by observations and travelers' accounts of fossilized beaked dinosaur skeletons found in the Turpan and ...
