A ten foot tall raptor, with a chicken-like head and possibly covered in feathers roamed North America 66 million years ago, says a new study. A team of scientists identified this new species, Anzu wyliei, from three partial fossils found in North and South Dakota. These fossils gave paleontologists a more detailed picture of North American oviraptorosaurs, feathered and beaked dinosaurs that are more commonly found in Asia.
