Stuck wing
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.

Sticky trap
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."
Elephant transportation
In Myanmar, some locals use elephants for transportation, including for moving amber.

Mummified wing
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]
CT scan
The researchers were able to merge data about the bone and soft tissue together in this digital reconstruction.
Magnified wing
A close-up of Rose's wing shows the claw and a pale spot on the plumage.
Ancient feather
A magnified look at Rose's feathers shows where the feathers insert into the bird's skin.
Downy feathers
Rose's downy feathers are shown here inserting into the skin.
Wing feathers
Rose's overlapping flight feathers are shown here. Amber polishing gave the researchers a clearer view of the specimen.[Read the Full Story on the Mummified Bird Feathers]
