Four-winged dino may be missing bird link

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.

This visualization below allows you to see the impact that each user has on the current conversation. The top row contains the group of users who have had the most impact, the 2nd row the group of users who have had the 2nd most impact (et cetera). Users with similar impact are grouped together, and the average score of the group is shown to the left of the group. The author of the article is also shown on the left, in their corresponding group. Each user's score is based on the number of comments the user has made plus the number of votes their comments have received. The scores are calculated relative one another, so while their absolute value is not particularly important, their relative difference does indicate a larger difference in impact on the conversation.

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.

Good link, but you're a little behind the times. PBS did a NOVA special on this a year or more ago.

Watch the whole thing here:
