The following item came over the Associated Press wire and was printed in _The Washington Post_ on Monday, April 19, 1993, in "Science Notebook" on Page A2: Paleontology: Another Clude to Origin of Birds A long-legged, turkey-sized bird with powerful claws instead of wings and dinosaur traits such as a long tail and teeth sprinted in Mongolia about 70 million years ago, a fossil study says. The flightless creature represents a "bizarre new group of birds," and its characteristics may help scientists better understand the origins of birds, said researcher Mark Norell. The discovery of two well-preserved fossil specimens is reported in the current issue of Nature by Norell, of the American Museum of Natural History in New York, with colleagues there and in Mongolia. The creature combine bird characteristics and dinosaur traits, and its skeletal features show it is more closely related to modern birds than is the well-known, older _Archaeopteryx_, Norell said. Storrs Olsen, curator of birds at the Smithsonian Institution, who has examined the new specimens, called it "an extraordinary beast." But he declared, "There's no way that thing could be a bird." The differing interpretations reflect a longstanding debate over whether birds evolved from dinosaurs or developed independently. Norell supports the birds-from-dinosaurs idea; Olsen conceded that's the prevailing view, but said he does not consider it proven.
