Sticky tree resin captured the wings of two birds 99 million years ago in what is now Myanmar. Most feather fossils are in 2D specimens captured in sedimentary rock, so these findings are extraordinary, showing scientists the structure and color of ancient features during the Cretaceous age.

An ancient, hummingbird-size bird got its wing stuck in sticky tree resin and likely struggled for its life about 99 million years ago. Researchers nicknamed this specimen "Angel Wing."

In Myanmar, some locals use elephants for transportation, including for moving amber.

The other bird wing, nicknamed "Rose" by scientists, can be seen here encased in amber. It's possible that Rose was a severed limb that was torn off by a predator before that animal got stuck in amber. Or perhaps the wing floated free from the rest of the corpse due to resin flows, the researchers said. [Read the Full Story on the Mummified Bird Feathers]
