Pronounced Chin-Dow-Sauros, I reconstructed this deviating from what the public knows following Headden's 2013 reconstruction as posted on his blog: qilong.wordpress.com/2013/11/2…. This was no unicorn and due to taphonomic issues the rest of the crest has been lost. Who knows, it might as well have been an asian Corythosaurus but the truth is these nasal bones are far more complex than you'd think, and the "horn" is the only piece we got. Enjoy! Comments are welcome!
