Researchers Discover Largest Ever Dinosaur With Birdlike Wings and Feathers 47

sciencehabit writes: When we see birds winging their way across the sky, we are really looking at living dinosaurs—the only lineage of these mighty beasts that survived mass extinction. Yet before they went extinct, many dinosaurs sprouted wings themselves. Researchers now report finding the largest ever winged dino in China, a sleek, birdlike creature adorned with multiple layers of feathers all over its arms and torso that lived 125 million years ago. The dino was about 1.65 meters long, a little longer than a modern condor, but at an estimated 20 kilograms, it was probably nearly twice as heavy as that bird. It almost certainly could not fly, however—an important confirmation that wings and feathers originally evolved to serve other functions like attracting mates and keeping eggs warm.

      Other than leaping further, limbs would be just as useful if not more so than wings. Wings could also help you stop faster, if that was of any benefit.

  • I don't understand how scientists could use birdlike wings and feathers to find large dinosaurs.

    Read another piece yesterday that mentioned the find in question here was of a very, very close cousin to the good ol' Velociraptor. The conclusion there was that the Velociraptor was likely feathered as well, and not likely to look much like the leather/scaley beasts from the movies (and, um, they weren't that big, either, apparently).

      Future anthropologists probably won't realize we're feathered either.

      The movie mentioned that same thing about feathers and said that the public wanted big scary monsters with no feathers.

      Yeah, what they had in the movie looked like Deinonychus. But Velociraptor sounds like something more 12 year old boys would pay to see.

    It would suck to be a dino: your front arms are too short to yank off.

    (I was a grad student of John Ostrom's once upon a time.)

    This may be "the first evidence of feather morphologies and distribution in a short-armed (and probably non-volant) dromaeosaurid" but this dinosaur says nothing about the origins of flight feathers. It lived 25 million years AFTER Archaeopteryx, so there were certainly flight feathers around for a very long time before it. This is really no more surprising than the fact that ostriches and emus still have feathers.

    The real question, which remains unanswered, is the exact relationship between dromaeosurids and birds and whether flight originated from the ground up (use of drag to control running) or the top down (use of drag to create lift).

    they are birds. It's called speciation.

    • My first thought on that was that surely crocodiles, alligators, and turtles are also modern descendants of the dinosaur lineage. I don't think they evolved from small mammals.

        No... Just like mammals are not descendants of dinosaurs. Not all prehistoric animals were dinosaurs, only the birds were. The reptile and mammal ancestors were contemporary with dinosaurs but were different groups. Think of them as respectively furry, scaly and feathered prehistoric -saurs, with the feathered being the dinos.

      • Crocodilians (crocs and alligators), testudinid (turtles and tortoises), dinosaurs (including their minor group of birds), are all archosaurs, along with some extinct groups like mosasaurs. Lizards and snakes are on a different lineage. I forget where the pterosaurs fit in.

        "Reptile" is a taxonomic bucket list. Best avoided.

        Mammals are more closely related to the archosaurs than the lizards.

      "Dinosaur" is not a species. Nor is "bird."

    • Birds are dinosaurs because they are the descendants of dinosaurs. It's called taxonomy.

    ...that we know of so far. There could have been a larger one we haven't discovered yet.

  • They depict a large fearsome creature in blue. Not at all like a friendly yellow bird. So it is not Big Bird.
