Dinosaur and early bird feathers trapped in amber around 80 million years ago provide unprecedented insight into the evolution of plumage.
After rummaging through thousands of amber inclusions housed at the University of Alberta and the Royal Tyrrell Museum of Paleontology in Canada, researchers discovered 11 amber encased-feather fossils that provide the most detailed picture yet of ea
Using synchrotron rapid scanning X-ray fluorescence to map the distribution of trace metals in avian fossils over 120 million-year-old, researchers reconstruct the pigment patterns of their feathers—revealing some of the extinct birds' long-lost colo
Researchers map pigments in early bird fossils using preserved metallic residues.
