4-Winged Proto-Bird Unearthed In China; Predates Archaeopteryx 140

Wired reports on a find described September 24 in a note at Nature and the day after at the annual meeting of the Society of Vertebrate Paleontology: a dinosaur fossil bearing true feathers on four limbs. The fossil was discovered in northeastern China, in strata believed to have been deposited between 151 million and 161 million years ago. If that estimate is correct, the newly discovered Anchiornis huxleyi is at least one million years older than the believed age of the more famous winged dinosaur Archaeopteryx.

    like a year ago on Nova.

    http://www.pbs.org/wgbh/nova/microraptor/program.html [pbs.org]

    And from the documentary, it was obvious that the discovery had been made some time prior to the making of the show.

    So this is old news. I guess dinosaur news travels slowly.

      I also remember watching that document and was fascinated. However, a few wordings from TFA are interesting.

      In fact it does refer to the microraptor (which parent's link is about). "A similar configuration has been seen in other feathered dinosaurs, including Microraptor* (SN: 1/27/07, p. 53) and Archaeopteryx (SN: 9/23/06, p. 197)." So they know it is similar to earlier findings.

      "...is the oldest known to have sported feathers and is estimated to be between 1 million and 11 million years older than Archaeopteryx, the first known bird..."

      So they have found yet another feathered, four winged dinosaur. All such findings help us understand more of them. In addition, this one appears to be older than the previous findings which again gives us a bit better image of what happened and when. I'm interested to see how this thing is different from microraptor. So they seem to have made findings that are nothing revolutionary but give us again a bit better image of what has happened, how and when. Probably some news sources misinterpreted that to mean much more than it does

    • Sorry, microraptor (covered in the nova story) dates from the early Cretaceous, well after Archaeopteryx. This new find dates from the late Jurassic but pre-dates Archaeopteryx finds. This fossil was just found this year. Not every four winged dinosaur with feathers is the same. Jeeze.

      Just one problem: we're talking about two different animals here. The PBS critter is Microraptor, found in at least 2003, while the new four-wing in TFA is Anchiornis (and it's older than Microraptor, which is an important part of the story).

      Where are all the transitional species?

      This is an old, tired anti-evolutionary argument. The answer is that every single fossil we find is a transitional species. Unfortunately fossilization is an incredibly unlikely event, and a fossil surviving for tens of millions of years and then happening to be uncovered even more incredibly unlikely, so the fossil record simply doesn't contain every species that ever existed. We may never find the real ancestor of all modern birds, just cousins of it like Archaeopteryx. So what? The fact that birds evolved from dinosaurs is irrefutable.

      The problem is the date for feathers keeps getting pushed back and there have even been early lizards found with what appear to be feathers.

      I assume you're referring to Longisquama. There is good reason to doubt that those structures were even real, let alone feathers.

      One massive gap is if birds evolved from dinosaurs where are all the tree dwelling dinos?

      What are you talking about? First, the division between "bird" and "dinosaur" is entirely arbitrary. Birds, in a very real sense, ARE dinosaurs. We just draw an arbitrary line in the sand and say the things on one side are dinosaurs and the things on the other side are birds, but there's no hard and fast reason to draw the line at any particular spot. Archaeopteryx really doesn't look all that different from the raptors that came before it, and still has a very dinosaur-like head and no beak. Is it a bird?

      Early birds were likely ground dwellers, just like the raptors they evolved from. We don't know precisely when tree-dwelling evolved, because we don't have enough fossils to be able to tell. I fail to see how this is a "massive gap"; it's a minor question at best.

      Odds are birds branched off very early on and were a separate line of evolution so saying birds evolved from dinosaurs is kind of like saying we evolved from chimpanzee.s

      Nonsense. Saying birds evolved from Archaeopteryx would be like saying we evolved from chimps -- not all that far wrong, but wrong. Saying birds evolved from dinosaurs is like saying we evolved from primates. Dinosaurs are a very, very big group, and there is absolutely no doubt that birds evolved from them.

        You miss the poster's point. He isn't saying that evolution didn't happen. He is positing that he believes the divergence happened WAY sooner than what the 'consensus' claims. He believes that having feathers and not having feathers is a large enough evolutionary gap, and we have enough fossils from the currently believed deliverance period, that if the time line were correct, we would see a lot of intermediary fossils.

        To poster isn't saying that birds didn't evolve from dinosaurs. He is saying that he believes that by just saying 'evolved from dinosaurs' implies that it happened towards the middle or end of their existence as opposed to the beginning. This leads to many people making a perfectly reasonable but incorrect conclusion as to when it happened, while adding nothing to those that correctly understand the statement. Since, if the divergence happened as early as the poster believes, basically all complex animals evolved from 'dinosours'. Since the statement adds nothing for those who are not confused by it, but gives the wrong conclusion to people who are confused by it, from a pragmatic standpoint, it is wrong.

        Of course, it being right or wrong depends on when birds actually first appeared. I'm not arguing that. I'm just pointing out that you are misunderstanding the parent poster.
