PALEONTOLOGY:
Plucking the Feathered Dinosaur
Ann Gibbons
A year ago, the so-called "feathered dinosaur" Sinosauropteryx made the front page of The New York Times, and was viewed by some as confirming the dinosaurian origins of birds. But at this year's vertebrate paleontology meeting in Chicago late last month, the verdict was a bit different: The structures are not modern feathers, say the roughly half-dozen Western paleontologists who have seen the specimens. But just what the structures are--and whether they link birds and dinosaurs--is still under debate.
