The Facts About Dinosaurs & Feathers

  • Publicado el 27 nov 2017
  • Over the past 20 years, dinosaurs of all types and sizes have been found with some sort of fluff or even full-on plumage. These fuzzy discoveries have raised a whole batch of new questions so we're here to tell you everything we know about dinosaurs and feathers.

    Let's not forget that birds are naked under the skin, not scaly. And that scales on bird feet, and maybe elsewhere on dinosaurs, are former feathers. The origin of feathers in embryo birds is at the lower back and over the pelvis, probably recapitulating phylogeny as this is where you find proto-feathers on non-bird dinosaurs.

    Doesn't moving Theropods to be a members or closer relatives of the Ornithischia just solve this. It makes sense considering extant theropods have bird like hipbones (because they are birds) and having the dinosaurs with similar hips and feathers grouped together makes so much more sense then separated.

    Those dinosaurs that didn't have feathers actually did, but thought it fashionable to wax them off. Interestingly enough there were also dinosaurs that thought it would be cool to wax their feathers into curls, reminiscent of a fossil called Ischíosaurs (the "Hip-lizard"), who was doing it before it was cool. Some dinosaurs plucked their eyebrows, and filled them back in to make them appear thicker. While others went all natural claiming #nomakeup on their social media. Fascinating stuff.

It literally has no reason to keep its feathers because they were only a detriment to a predator specialized in killing large, powerful prey."
    Ya know, the arguments people supporting a featherless rex have made for years.

    There's no denying the striking similarities (and presumably exceedingly close relationship) between coelurosaurian theropods and birds (i.e., maniraptorans, i.e., paravians etc etc.) However I am disturbed by this "incontrovertible evidence" that birds EVOLVED from warm-blooded, chicken-sized coelurosaurian theropods who were terrestrial and covered in "Dino-fuzz". There is some serious flaw in methodology, absence of rigorous science, and dangerously religious ethos driving this sudden "renaissance" in our understanding of avian evolution. Where are all the paleontologists practicing actual science (rigorous attempts at refuting REFUTABLE hypotheses, rather than "proving their theories")?
    The entire Prum model for feather evolution is literally Platonic in nature. Plato, while himself 'slightly' more clever than the simplistic misinterpretation/application of his thought experiments in "perfect forms"... This was literally the regression in natural philosophy that was responsible for the DARK AGES.
    It seems to me that the entire foundation of the "dino-to-bird" transition has been grossly misrepresented, and ironically those who offer very scientific refutation (attempts to reject this hypothesis) by pointing out Archaeopteryx is a BIRD (a primitive bird): some of these folks literally believe the world is 6000 yrs old. Why is no one calling the bluffs of tenure-hungry desperate nerds who apply a fervor and shortsightedness to evolution of flight and birds themselves with the same neurotic "cladistics" they might use to arrange their Star Wars figurines alphanumerically by episode and planet?
    This simply is not science, and it should cause no offense to a real scientist to point such fundamentals out in public. This is literally anti-science, by definition.

    As soon as it was recognized that birds were descended from a clade of dinosaurs, it ought to have been immediately clear that other members of that clade, and very likely other related clades, must themselves have been feathered. Archaeopteryx has developed flight feathers. These are specialized, complex structures that cannot have arisen all at once. They must have developed from something simpler.
    This isn't usually brought out, but I very much doubt that paleontologists were all that surprised when evidence of feathers in all sorts of dinosaur clades were noticed.

    • Randall Wilks
      Randall Wilks Hace 2 meses

      They were not birds. Dinosaur evolution did not stop with birds. Evolution is an ongoing series of natural experiments where what works gets perpetuated and those that don't, perish. Dromeosaurs like microraptor and its relatives were successful for a time as there are a fair number of them in museum collections. Not certain how well they could fly, but they could certainly glide.

    I always assumed because of dinosaurs size finding coverage from the sun would be difficult. Feathers would act like a heatsink dissipating body warmth through the stalk and out the bristles.

    • Randall Wilks
      Randall Wilks Hace 2 meses

      If you look at large mammals in warm climates, they don't have much hair as they have more problem dissipating heat than retaining it, so even though most theropods had feathers, they would be less likely on an adult T-Rex. Feathers on birds are not just for insulation, they are used for display as well, so perhaps they retained some for that purpose.

    As one who works with, plays with, and studies birds, (and specializing in ravens) I'm going to predict most of this is incorrectly interpreted. I'd love to be a fly on the Chinese paleontology wall, every time they find something that has any indication of lines coming out from a fossil (and of course they'd never add any...) the American dollar signs dance above their "grant" loving heads... a feather, the skin that holds and directs it, and the interaction with the brain are unbelievably complex. I'd like to know how a dinosaur brain, created the density of a bird brain? It's like comparing a 500mb (dinosaur brain) memory chip to a 5T (bird brain) memory chip. That's quite a leap.

      Well, everyone of us is right. The first protofeathers looked most likely just like thick hairs, although they were actually elongated scales. Those helped to keep the dinosaurs warm, just like the hairs on mammals. But instead of getting more hair and eventually fur, like mammals, those feathers split up and became the down feathers and cover feathers today's birds have. There were most likely some pretty fluffy dinosaurs back then.

      It is not possible. The common ancestor of mammals and reptiles was cold blooded. It wouldn't have needed filaments unless it used them as sensory organs. No reptiles have hair or whiskers (other than feather whiskers), so that can be safely ruled out. Also I think there is a keratin in bird feathers that is only found in the embryonic stages of alligator scales. So yep, it is not possible. But they do look similar.
