A dinosaur tail preserved in amber with both bones and feathers intact is opening new doors for scientists.
The specimen was discovered in 2015 in an amber mine in Myanmmar.
The discovery allows scientists to take CT scans to get details of the bones and feathers to see how they attach to the skin.
The tail was that of a juvenile theropod dinosaur the size of a sparrow from about 99 million years ago.
Ryan McKellar Curator of Invertebrate Palaeontology at the Royal Saskatchewan Museum said this could mean certain dinosaurs may have been covered in feathers.
The discovery is being called a once in a life time finding.
