For the past decade, dinosaur scientists have been puzzling over a set of fossil bones they variously describe as weird and bizarre. Now they've figured out what animal they belonged to: a bird-like creature they're calling "the chicken from hell."

In the fall, newly equipped with adult plumage, she flew thousands of miles south until she reached the coast of Maryland. And this winter, she became an important part of an unprecedented research project.
