The primitive, hair-like feathers known as protofeathers likely belonged to theropods — dinosaurs similar to tiny Tyrannosaurus rexes — that roamed the swampy forests of Alberta 80 million years ago, said Alexander P. Wolfe, a University of Alberta earth sciences professor who co-authored the research published Thursday in Science.
noticed that some of the feathers resemble those found on modern birds, complete with barbs sporting tiny Velcro-like hooks that lock onto adjacent barbs to create a sturdy flight surface. Some of these fragments likely came from a flight-capable bird.
The oldest bird, Archaeopteryx, lived in what is now Germany about 150 million years ago, and the oldest known feathered dinosaur, Anchiornis huxleyi, lived in northeastern China between 151 million and 161 million years ago.
