A team of researchers from the University of Bristol have found a dinosaur tail almost perfectly preserved in amber - covered in feathers.
The discovery was made in Myanmar in a joint project with teams from Canada and China.
Fossil evidence had previously indicated that many dinosaurs did have feathers, and while these are not the first to be found in amber, it is the first time they can be definitively linked to an animal.
The researchers say the specimen is about 99 million years old, dating back to the mid-cretaceous period.
The feathered tail is from a theropod - a group of dinosaurs that walked on two legs and were largely carnivorous.
The initial discovery was made by Lida Xing from the China University of Geosciences in Beijing who came across the remarkable specimen at an amber market in Myitkyina, Myanmar in 2015.
Ryan McKeller, from the Royal Saskatchewan Museum in Canada, says they can be confident the tail is that of a dinosaur and not a bird:
The research team say they're now eager to find more specimens from the region.
