Beautiful Feathered Dinosaur’s Tail Found Preserved 99-Million-Old Amber Fossil
Beautiful Feathered Dinosaur’s Tail Found Preserved 99-Million-Old Amber Fossil: Our past holds the key to our present and future. This’s very same when it comes to our and other species’ evolution on this planet. For millions of years, the dinosaurs had roamed the Earth and then they became extinct leaving us with fossils and clues as to how life was back then. Recently, the scientists have discovered a piece of amber that contained feathered dinosaur’s tail from the mid-cretaceous period which sheds new light on the evolution of bird plumage.
The amber is 99 million years old and belonged to mid-Cretaceous time. The tail is believed to belong to a juvenile coelurosaur, a close relative of birds, and has a chestnut-brown upper surface and white underside.
Lida Xing from the China University of Geosciences in Beijing and Ryan McKellar from the Royal Saskatchewan Museum in Canada have published a study of the amber fossil on Current Biology. Though it is not new to find feathers in ambers, there has never been a complete part, such as a tail in this case, of a dinosaur preserved in it. The researchers believe that the dinosaur is a juvenile and about the size of a sparrow.
