Dinosaurs are called 恐龙 (Frightening Dragons) in Chinese.
The dinosaurs can't be named after dragons if dragons had not existed first in the minds of the Chinese, prior to the discovery of (fossilized) dinosaurs.

A step into the quite-fictitious-but-also-near-to-fact past:
In HDSD Chapter 12:
As for Ji Xiaofu, her internal injury had been caused by poison. After Zhang Wuji had ascertained its roots, he had combatted it with a decoction of raw fossil fragments (sheng1 long2 gu3), perilla (su1 mu4), mole cricket (tu2 gou3), Trogopterus dung (wu3 ling2 zhi1), Caper Euphorbia seed (qian1 jin1 zi3) and powdered toad (ge2 fen3).
Raw Fossil Fragments (sheng1 long gu3) is 生龙骨.
The 龙骨 here refers to "dinosaur bones".
