… and Ostriches. "Some old tail feathers are shedding new light on the link between dinosaurs and modern-day birds, and scientists simply can't contain their excitement. When the well-preserved partial skeleton and rare soft tissue of an Ornithomimus dinosaur was unearthed in the badlands of southwestern Alberta, Canada, in 2009, scientists also found its fossilized feathers. A new analysis of the feathers, which was published in the journal Cretaceous Research on Wednesday, suggests what the plumage might have looked like and what it was used for. "We've known that birds and theropod dinosaurs had a common ancestor for at least 15 years now," Dr. Alexander Wolfe, an adjunct professor of paleobiology at the University of Alberta and a co-author of the research, told The Huffington Post in an email. "But we didn't expect a dinosaur that clearly did not fly, Ornithomimus, to have the same basic feather architecture, structure, and composition as birds. So the similarities appear even greater with this specimen, and imply that essentially modern bird feathers evolved before flight." link Main page
