Siberian Discovery Suggests Almost All Dinosaurs Were Feathered 139

A new study published in Science (abstract) suggests that most dinosaurs were covered with feathers. This conclusion was drawn after the discovery of fossils belonging to a 1.5-meter-long, two-legged dinosaur called Kulindadromeus zabaikalicus. "The fossils, which included six skulls and many more bones, greatly broaden the number of families of dinosaurs sporting feathers—downy, ribboned, and thin ones in this case—indicating that plumes evolved from the scales that covered earlier reptiles, probably as insulation." Its distinctiveness from earlier theropod fossil discoveries suggests that feathered dinosaurs appeared much further back in history than previously thought. Paleontologist Stephen Brusatte said, "This does mean that we can now be very confident that feathers weren't just an invention of birds and their closest relatives, but evolved much deeper in dinosaur history. I think that the common ancestor of dinosaurs probably had feathers, and that all dinosaurs had some type of feather, just like all mammals have some type of hair."

        You think a T-Rex "chicken" wouldn't be scary? Imagine a 15 foot tall, 40 foot long bird of prey with a 4 foot jaw and 9 inch long teeth. Your average adult human would be finger food - a bite or two and then gone. This gets even more terrifying if you imagine them as giant cockatoos (and if you know how nasty cockatoos can be).

          I worked a good many years in an exotic pet store. My area of expertise was reptiles and, in my time, i was bitten by all manner of things that most people don't want to get bitten by. Of all the animals i would deal with, the birds were the things that really terrified me.

          Reptiles, yeah, you gotta repect them, esspecially the highly venemous ones. But, they are predictable and easily outsmarted. Birds can be fierce opponents. They are intelligence combined with effective weapons. They can deduce it's better to ignore the leather glove and aim for the exposed forearm. There was one macaw that i swear would pretend to be nice just to lull me into a vulnerable position.

          Not a day goes by that i'm not thankful that i live in a world where i only have to worry about sharks, big cats, bears, wolves, and reptiles. I would be terrified having to worry about a bird that might get me.

These birds' jaws are powerful enough to crush bone and intelligent enough to plan out actions. Like you said, a reptile might strike you but you'd see it coming. My in-laws' cockatoo does what that macaw you mentioned did. She will act all sweet and want you to pet her... until she decides to bite your finger off. She hasn't succeeded yet, but that's because we're extra cautious about body

      by Anonymous Coward

      For those of us who have been following the literature on the subject, this doesn't really come as a surprise. Rather than that this fossil shows that all/most dinosaurs had feathers where we previously assumed this to be the case only for some groups, this fossil is a confirmation of the already commonly held view (in the field) that feathers were to all probability basal in dinosaurs.

    • Find some more feathered fossils and conclude that ALL dinosaurs probably had feathers.

      It makes a little more sense to conclude something like that when the fossils are very old and of a different lineage than other feathered dinosaurs. The Guardian article does a much better job at explaining the reasoning than the NatGeo article.

      It's a broad leap, but they didn't just find some random feathered fossils. They found fossils of various species that shared an ancestor very early in the dinosaur line. So it would be like discovering that Humans, Orangutans and Gorillas all had something in common (like a particular lobe of the brain) that we had previously thought only humans had. It would imply the there is a good chance Chimpanzees have it too, because it seems likely to be inherited from that early shared ancestor. They could be wrong, and each of those lines of dinosaurs could have evolved feathers separately. But it's not just a random conclusion.
  • Pre-historic animals in Siberia mutated to grow feathers and withstand the blistering cold. That's called evolution. It still doesn't mean all dinossaurs were feathered. I bet in Australia they wore bathing suits.

    What exactly did all these different feathers do? "I don't know; nobody knows for sure," Godefroit says. "These animals couldn't fly, that's all we can tell you."

    Of course these dinosaurs couldn't fly; everyone knows that in the late Triassic, the Pterosaurs [wikipedia.org] received a broad-reaching patent titled "Feathery Apparatus for Flight". Regrettably, the patent term length at the time was over one hundred million years.

  • What's their definition of "most dinosaurs"? Maybe most as in, there was this one tiny feathered dinosaur that bred like rabbits and was everywhere? And do they mean "had feathers" as in had 3 tiny feathers on the top of a big lizardy dino head? Big dinos almost always had scales from what I've read. And perhaps size is part of is as is seen in recent animals and animals today... larger mammals have far far less fur except during the times of ice ages.

  • I've never understood this idea. Sure at a macroscopic scale there is some resemblance between scales and feathers, but on looking close you get an entirely different structure.

    Scales being basically flat plates and feathers being long rods with interconnected hooks on them.
