Guanlong wucaii

Guanlong (Crowned Dragon) is the best represented tyrannosauroid in the fossil record, and includes a spectacular name-prompting head crest which ran along its snout from nostrils to eye sockets. This crest was distinctly delicate—too flimsy for a weapon—and probably brightly colored to attract a mate or intimidate rivals. Like most early tyrannosauroids Guanlong may have been feathered, at least partially, though there is no hard evidence to support this theory. Yet.
(Crowned dragon from Wucaiwan)Etymology
Guanlong takes its name from the Chinese "Guan" (crown) and "long" (dragon)" in reference to its headcrest, the most elaborate of any known theropod dinosaur. The species epithet, wucaii, is derived from the Chinese "wucai" (five colours) and refers to the multi-hued rocks at Wucaiwan, the badlands where the fossils were found.
Discovery
The fossils of Guanlong were discovered in the Shishugou Formation at Wucaiwan, Junggar Basin, Xinjiang, northwestern China.
The holotype (IVPP V14531) consists of a reasonably complete and partially articulated adult skeleton. A referred specimen (IVPP V14532) is a fully articulated, nearly complete skeleton, though much smaller than the holotype.
