Scientists working in the Hukawng Valley in northern Myanmar have found something very special in a fragment of Cretaceous amber. The tail of a 99-million-year-old dinosaur, including bones, soft tissue, and even feathers, has been found preserved in amber, according to a report published today in the journal Current Biology. The wing of a bird, also from the Cretaceous period, was recently found in amber, but where the feathers of the ancient bird wing had the stiff central shaft and well developed structures to support flight, the feathers from the dinosaur tail were softer and more like the plumage some birds sprout for display. The dinosaur feathers feature a poorly defined central shaft (rachis) and appear to keel to either side of the tail.
