Dino-Era Bird Fossil Found; One of Oldest Known

A fossil of a new species of dinosaur-era bird found in China is one of the oldest ever discovered, experts say in a new study.

The new bird, called Eoconfuciusornis zhengi, or "the dawn of the Confucius bird," is predated only by the 150-million-year-old Archaeopteryx, which lived during the Jurassic period.

Chinese and British paleontologists discovered the well-preserved fossil along a forested lakeside in the country's northern Hebei Province.

"Eoconfuciusornis provides a new piece in the puzzle of the evolution from Archaeopteryx to more advanced birds," said study co-author Zhou Zhonghe, executive director of the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing.

Etched in Stone

The fossil bird likely plunged into a lake 131 million years ago, where it drifted to the bottom and was quickly covered in sediment. Over time the animal became encased in mudstone.

The specimen's fully developed, modern-looking wings and symmetrically balanced tail feathers were etched into the stone in curved lines of black and brown.

"The brown and black may reflect the original colors, but these might alternatively have been the bright reds, blues, and yellows of modern birds," said study co-author Mike Benton, a paleontologist at the University of Bristol in the United Kingdom.

Lead author Zhang Fucheng, a professor at the Beijing institute, added: "Eoconfuciusornis was extraordinarily well preserved for the fossil to have contained such depth of detail."

The study appeared recently in the journal Science in China.

Awkward to Smooth

Archaeopteryx was likely an awkward flier, weighted down with a long bony tail, teeth, and other physical features of a dinosaur.
