Feathered dinosaur
The feathered tail of a non-avialan (non-bird) theropod has been found preserved in mid-Cretaceous (∼99 mya) amber from Kachin State, Myanmar (Burma). The BBC describe it as "perfectly preserved". Lida Xing found it at an amber market in Myitkina, Myanmar. The amber was already polished for jewellery: the seller thought it was plant material. However, it was the tail of a feathered dinosaur about the size of a sparrow. The feathers were not flight feathers. Dr Paul Barrett, from London's Natural History Museum, called the specimen a "beautiful fossil", describing it as a "really rare occurrence of vertebrate material in amber".
