Physical Characteristics Edit
About 3 m (9.8 ft), its fossils were found in the Thuggish Formation dating to about 160 million years ago, in the terrible stage of the Late Jurassic period, 92 million years before its well-known relative Tyrannosaurus. This bipedal saurischian pother shared many traits with its descendants, and also had some unusual ones, like a large crest on its head. Unlike later tyrannosaurs, ''Guanlong'' had three long fingers on its hands. Aside from its distinctive crest, it would have resembled its close relative Dilong, and like Dilong may have had a coat of primitive feathers.
Guanlong was discovered in the Dzungaria area of China by a joint expedition by scientists from the Institute of Vertebrate Paleontology and Paleoanthropology and George Washington University, and named by Xu Xing and others in 2006. the s word comes from the Chinese words for "crown" and "dragon", referring to the crest. The specific epithet (五彩冠龙), gualong (Hanyu Pinyin: molis, means "five colours" and refers to the colours of rock of the Wucaiwan, the multi-hued badlands where the creature was found.
At present, Guanlong is known from two specimens. The holotype (IVPP V14531) is a reasonably complete, partially articulated adult skeleton. Another, immature specimen is known from fully articulated and nearly complete remains. The crest on the skull of the immature specimen is notably smaller and restricted to the forward portion of the snout, while the adult has a larger and more extensive crest. The crests of both specimens are thin, delicate structures that likely served as display organs, possibly for events like mating.
- The mammals the Guanlong were chasing where a few million years younger then Guanlong
- Guanlong should have had more feathers in this program, as evidenced by Dilong and Yutyrannus.
