Mei Long, the Soundly Sleeping Dragon, is a fossil of a juvenile troodont that demonstrates another link between birds and these dinosaurs. It died in a curled, heat-preserving posture, apparently in its sleep — with its head tucked beneath its forelimb. The posture immediately recalls birds sleeping with head tucked under wing. PZ Myers at Pharyngul has the details and diagrams in his 2004 article, “Mei Long, the Sleeping Dragon.”
