Alan Feduccia, a paleontologist at the University of North Carolina, is one a few paleontologists who reject the bird-from-dino theory."A lot of things look like feathers," he says. "Where ever birds came from, it's much earlier [than the new fossil]. There's this timing problem." Norell counters it isn't useful to think of evolution as a linear process. "When you're looking at these animals, you're really looking at a family tree," he says. Because dromaeosaurs are more primitive than birds, Norell believes the new fossil shows that feathers developed before flight, perhaps along with warm-bloodedness. Scientists says they won't know if the fossilized creature represents a new species until they see three-dimensional CAT scans of its bones. It will be on display through the summer at the Museum of Natural History in New York.
