the dinosaur equivalent of a peacock's iridescent plumage. Vivid evidence for that theory appeared when scientists unveiled the true colors of 125-million-year-old feathers. Bird feathers and ...

Prior research has shown that patterns in melanosomes can be used to determine feather, fur, or skin coloring. This has led other research teams to learn about the coloring of many types of dinosaurs.

But there is one natural wonder that just about all of us can see, simply by stepping outside: dinosaurs using their feathers to fly. Birds are so common, even in the most paved-over places on ...

Feathers are among the most complex cutaneous ... emerged around 200 million years ago in certain dinosaurs. Paleontologists continue to discuss the possibility of their even earlier presence ...
