I had some time before I took some more medications to do some of this. By request from Arri here is the Mei long

Pronounced: my-long
Length: 21 inches
Weight: 8 pounds
When it lived: 130 MYA
Where found: Liaoning Province, China
TheOctober 13, 2004, National Geographic News carried a story on the new dinosaur recently discovered in China, quickly dubbed, "The sleeping dragon." because of its posture. The new fossil specimen is an almost fully grown adult. It sits on long, folded hind limbs. Its forelimbs are folded birdlike next to its body and its neck curves to the left, so that its relatively small head lies between the left elbow and body. "I never expected we'd find a sleeping dinosaur in general, let alone with the tuck-in position," said Xu Xing, a curator at the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing, China.
Mark Norell, chairman of the division of paleontology at the American Museum of Natural History in New York, said the discovery further strengthens the chain linking dinosaurs and birds, suggesting this birdlike sleeping posture first evolved in dinosaurs. "This is another stereotypical bird behavior in another nonavian theropod," he said. Theropods are meat-eating dinosaurs characterized by short forelimbs and powerful hind legs. Many scientists believe small theropods are ancestors to the first birds. The posture is identical to the "tuck-in" posture of many living birds, according to Xu and Norell.
Mei long was found in layers of volcanic and riverbed sediment that have been dated to about 130 million years ago. At that time, Liaoning Province was a volcanically active, forested region filled with lakes and streams. "It is kind of difficult to imagine how a fossil can be preserved in such a posture. It must be like it instantly died and was buried," Xu said. Scientists are uncertain as to exactly how the fossil was preserved. Sues and Philip Currie, curator of dinosaurs at the Royal Tyrell Museum in Alberta, Canada, point out that an incomplete troodontid skeleton from Mongolia, Sinornithoides, was discovered in 1994 in a similar pose. "Overall, I think [Mei long] is a very remarkable find and is especially amazing because it is the second small troodontid in this pose," Currie said. "Not much doubt that this is the way they slept."
While feathered-dinosaur discoveries are becoming almost routine, the discovery of a sleeping dinosaur is a rare surprise, Norell said. "There are so very few fossils of animals which are basically buried alive, preserving behavior that's interesting." [/size]
