Chinese paleontologist Xing Lida bought this piece of amber in a gem market in norther Burma. The seller thought it had a piece of ancient plant inside, but that isn't a plant; it's the tail of a small predatory dinosaur that lived 99 million years ago.
Detail. This dinosaur was about the size of a sparrow. The piece of amber is, according to CNN, "about the size of a dried apricot."
