Four-winged dino may be missing link in bird debate

PARIS (AFP) – The stunning remains of a “four-winged” dinosaur have confirmed that birds owe their ancestry to two-footed dinosaurs that lived millions of years ago, the world’s most famous fossil-hunter said.

Xing Xu of the Chinese Academy of Science in Beijing is staking the claim thanks to an astonishingly-preserved fossil of a bird-like dinosaur called Anchiornis huxleyi.

Until now, A. huxleyi was thought to be a primitive bird. It was presumed to have been a near-contemporary of Archaeopteryx, the first recognised bird, which flew around 150 million years ago.

But these opinions were based on an incomplete fossil.

The new, nearly-complete specimen gives a different picture, suggesting that A. huxleyi is millions of years older than Archaeopteryx and has both dinosaur and avian features.

It is the long-sought evidence that proves birds descended from theropod dinosaurs, argues Xu.

Soooo.... Two-winged critters are more complex than four-winged?
That doesn’t make any sense.
