Changmiania

Changmiania (from the Chinese "changmian", meaning "eternal sleep") is a genus of basal ornithopod dinosaur that lived in what is now China during the Early Cretaceous. It contains a single species, Changmiania liaoningensis.

==Discovery and naming== The taxon is represented by two near-complete articulated skeletons: the holotype specimen, PMOL AD00114; and a referred specimen, PMOL LFV022. These remains were discovered in the Barremian age, 123.2 million years old, Lujiatun Beds of the Yixian Formation by local farmers and partially prepared. They were acquired by the Paleontological Museum of Liaoning at Shenyang, which completed the preparation. No indications were found that the fossils had been tampered with by fossil thieves. The perfect life-like positions of these specimens suggest that they were buried alive, possibly in their own burrows due to a volcanic eruption.
