“It’s a once in a lifetime find. The finest details are visible and in three dimensions,” Ryan McKellar, a paleontologist at the Royal Saskatchwan Museum in Canada confirmed. Fragments of dinosaur-era bird wings have been found preserved in amber before but this is the first time part of a mummified dinosaur skeleton has been discovered. The tail section belongs to a young coelurosaurian — from the same group of dinosaurs as the predatory velociraptors and the tyrannosaurus. The amber, which weighs 6.5 grams, contains bone fragments and feathers, adding to mounting fossil evidence that many dinosaurs sported primitive plumage rather than scales. Scientists believe the creature would have had a whip-like tail like a mouse but covered with contour feathers similar to those that give shape and color to birds. Soft tissue and decayed blood from the tail were found in the amber but no genetic material was preserved.
