All the science journalists are talking about the bird feathers found in amber (solidified tree sap). The unique specimens from Myanmar (formerly Burma), announced in Nature Communications, provide the clearest evidence yet for bird feather structure and color in fossils. The asymmetrical flight feathers, with claws on the wing tips, indicate that the extinct birds that were strong flyers. Some secondary feathers, tissue and bone were also preserved, including the alula. The remains are said to be mummified, but no original biological material was reported. The feathers show patterning with stripes and spots, and for the first time in amber, show attachments to bone, giving paleontologists additional anatomical details to work with.
