Discovery of new bird species in China, oldest beak shows evolution complexity

sornis was a ground-living predator whose beak may have been hooked like a hawk, and this restoration was recently featured as a cover of Scientific American," Martin said. "The new fossil shows something very different. The beak is pointed and turned up at the tip very much like the cartoon bird Woody Woodpecker."

Combining modern and ancient features in the same skull was surprising, he said.

"This is very much like having the space shuttle with a back end built like a Model T."

Dui, the new specimen, also shows that the half-moon shaped bone in the wrist that's been used to support a dinosaurian ancestry for birds is the same in Confusciusornis and Archaeopteryx as in modern birds, but is a different bone in dinosaurs, Martin said.

"It no longer can be one of the main supports for a dinosaurian origin of birds," he said.
