Velociraptor Had Feathers 189

Spy der Mann writes "A new look at some old bones have shown that velociraptor, the dinosaur made famous in the movie Jurassic Park, had feathers. A paper describing the discovery, made by paleontologists at the American Museum of Natural History and the Field Museum of Natural History, appears in the Sept. 21 issue of the journal Science."

    What was depicted in the movie Jurassic Park was clearly Deinonychus. Velociraptor didn't have that large inner claw. In fact, the name Deinonychus means Terrible Claw while Velociraptor means Speedy Predator. I suspect they misnamed the dinosaur in the movie because the name Raptor was more marketable to children.

      I think you'll find it was just computer generated.
    • Velociraptors as big as the ones in the film weren't found when the first Jurassic Park movie was made, and anyway they had flatter snouts. The animals in the movie were always Deinonychii (pl?), with that rounder head, rigid tail and sickle claw on each foot.

      Just looked up when the Utah raptor was discovered - 1993 according to Wikipedia. Hmm... might be close either way. The book was from '90 and the film was released in '93. Hmm...

      Deinonychus was rechristened by some authors, which happens moreoften, like the all known Brontosaurus which is named Apatosaurus.

      There have been renamings all along, including to believe in a species and revoking his own line. Happened to the Gorgosaurus, too. Depends which line of Paleonotology you follow, there was always big debate over such things from the beginning of this science.

      Velociraptor does not mean Speedy Predator, raptor means theif.

      And the Megaraptor, not the Deinonychus, was the villan of the JP movies.

      They were velociraptors in the novel. Whether it was Crichton, Spielberg, or someone else at fault for any inaccuracies in the visual description or portrayal of the creature, it was Crichton who wrote about velociraptors, and I somehow doubt that he did so in order to make his novel marketable to children.

      I thought the general consensus was that the JP "Velociraptor" was definitely to big for a Velociraptor and probably a bit too big for Deinonychus, and probably most similar in size and body plan to Utahraptor (though a bit small); at any rate, most likely, the CGI critter was designed based on Velociraptor and then scaled up till had the desired dramatic appearance on screen, so calling it "clearly" any particular bird is probably mistaken; it is a fictional creation based loosely on then-current ideas about Velociraptor adapted to fit a particular theatrical vision.

      Velociraptor didn't have that large inner claw.


      Actually, the "sickle claw" is a distinguishing feature of the family Dromosauridae of which Deinonychus, Utahraptor, Velociraptor, and a whole host of other relatives are members.

    I wonder why other velociraptor fossils haven't been found with feathers, if all velociraptors had them? If this is the first one where feathers were identified then I'd ask if it really is the same species. Is it possible that this new fossil is a different species, but one where the skeleton was close enough to velociraptor that a fossilized version is originally identified as one?

      the suspicion is that all dinosours had feathers.

      Feather are made from the same stuff as scales, chitin (snakes and so on), its just a form of scale thats better suited to temperature regulation. Having feathers did not mean flight was even possible, that would have required specific adaption that feathers would probably have helped, but it would have been some environmental push, not the feathers themselves that caused birds to emerge.

        Feathers/scales/hair/fingernails are all made of keratin, not chitin. Feathers are a form of scales??? Why the fax machine is nothing but a waffle iron with a phone attached!
      • the suspicion is that all dinosours had feathers.

        I don't think that is theory, but instead that quite a lot of theropod dinosaurs (aside from birds, which are theropod dinosaurs and indisputably have feathers) had feathers, and that many that have not been previously recognized as such are actually not just "theropod dinosaurs with feathers", but actually birds (Velociraptor included.)
    • So is velociraptor going to be announced as the earliest known ancestor of birds?

      That would assume evolution works as a ladder - but it doesn't. It's more like a tree. This indicates that velociraptor *could* be an ancestor of birds; probably more likely is that they share a common ancestor.

    • Velociraptor was a late dinosaur. there had already been birds around for a while. Not a bird, just a distant cousin.

      Indications are that all dinos had down as young, probably had feathers growing up. May have lost them, if they were the large species, may not have. All the species I am aware of had stones in the chest cavity, when found whole, indicative of a gizzard. Like birds, the large species also had hollow bones. That saves weight. In birds, it helps the power to weight ratio which is vital for flig
      • Preditor/prey ratios also indicate that they were warm blooded.
        ...And the massive size of the largest dinosaurs entirely precludes the possibility of being warm blooded, lest they have to eat for more hours than there is in a day to maintain their weight.
    • I wonder why other velociraptor fossils haven't been found with feathers, if all velociraptors had them?


      There has been considerable, IIRC, evidence of feathers in velociraptor fossils previously, and evidence of feathers throughout the same family, which there is some reason to believe are actually birds. But feathers don't fossilize really well, and most of the evidence for velociraptor in particular has been indirect indications.

    • So is velociraptor going to be announced as the earliest known ancestor of birds?


      Probably not; IIRC, there is some evidence the other way around, that is, that Archaeopteryx, generally accepted as the first bird, may be an ancestor of Velociraptor, which would then be a flightless bird.

        ... Archaeopteryx, generally accepted as the first bird, may be an ancestor of Velociraptor, which would then be a flightless bird.

        Minor quibble: Some of the bird fossils recently found in China are dated to a few millions years before the earliest Archaeopterix fossils, and appear somewhat more modern in many respects. It's more likely that Archaeopterix was in a clade that branched off early, and died out. But this is all still a lot of speculation, as there are significant error bars on all the dates.

    Constantly being tarred and feathered, the poor velociraptors were often the butt of the larger dinosaurs' jokes.

    Nowhere is there proof that the 'raptors actually grew those feathers out of their skin!

    • Yes, the raptors should be brought back... but not to feed the portly. Rather, to cull the herd.

      You can bet that more people will stick to their diets (or "lifestyle changes" if "diet" is too non-PC) if their intact survival depends on outrunning velociraptors.

      Actually, there would be no possibility of outrunning the raptors. However, the principle still applies, since there would be a need to outrun the poor slob running next to you.

    See, in the article it mentions briefly before getting to the feather part that the Veliciraptor may be smaller than originally thought. Then it goes on about how this guy found bumps on the arm bone that correspond to bumps on the same bone in birds. Alright. But then it mentions that the bumps have never been found on any Velociraptor bones before.

    My question: Why is the conclusion that Velociraptor had feathers and not that they've discovered a different species?
  • I was very disappointed to hear that they now believe velociraptors had feathers. Not very menacing when they look like tall chickens.

    The process of discovering this new feathery information was shown in a lame IMAX documentary called Dinosaurs Alive! [dinosalive.com], narrated by Michael Douglas. It's playing now in a number of markets as both a 2D and 3D film.

      Isn't that like saying that a lion doesn't look so menacing since it's fluffy and looks like a kitty from a distance?

      I suspect they probably looked a little more menacing than simply a chicken. :-P
