I’m going to say this right up front: We have found dinosaurs with feathers. That’s a confirmed fact. Small carnivores make up most of the species with this particular trait. Velociraptor had quill knobs on its arm bones, which served as points where long feathers attached. Microraptor had four fully developed wings. Others were covered in what looks like a downy covering, possibly for insulation. There’s even a medium-sized Tyrannosaur with down on its hide (although I think T. rex in particular has been found to have scales instead, and any addition of feathers is pure speculation).
But as I look over the blogosphere and hear the words of fellow dinosaur fanatics, there arises a hysterical cry that scaly theropods (carnivorous dinosaurs), especially raptors, should be tarred and…well, feathered. Fictional treatments of dinosaurs in books, movies, and TV shows are practically burned in effigy if a small carnivore shows up naked (scaly). Tyrannosaurs and allosaurs and abelisaurs can be tolerated without down or full feathers, but God help you if there’s a Deinonychus or Ornitholestes that isn’t fuzzy.
Notice that I said fictional. As in, stories told for entertainment, which are often known for fudging scientific accuracy. That should be expected and understood, even when the creators try to be accurate. This gets you about as far as saying “You can’t hear explosions in space!” We already know that. Now are you going to sit down and watch Star Wars, or do I have to ask you to leave?
I kid you not, one unpleasant man insisted to me that the scaly Velociraptors of Jurassic Park were “abominations” even though their only crime is being outdated. Let’s get something straight, Jurassic Park was released in 1993, at which point any feathered raptors were speculative. The quill knobs on this species’s arms were examined in a paper published in 2007. Call me nuts, but “abomination” doesn’t quite fit.
To make matters worse, I’ve seen these self-important, melodramatic bloggers getting upset about episodes of Doctor Who and Terra Nova because they do have feathered dinosaurs, but they’re not “feathery enough.” Why count your blessings when movies and TV shows aren’t furthering your cause as hard as you want them to?
Allow a little artistic license. Come on, people know they’re not looking at real dinosaurs. The Doctor isn’t riding a real Triceratops, and Stephen Lang isn’t shooting an actual Carnotaurus. By all means, correct a museum display that shows a Deinonychus without a scrap of feathers on its skin, because that’s meant to be a scientifically accurate reconstruction. But even then, don’t lose your temper. That’s just childish.
And for the love of everything sacred and holy, stop telling me that dinosaurs had “denser” feather coatings than modern birds. That’s a little hard to establish when you point to feathers on (gasp) a dinosaur’s ankles. And when all you’ve got with dinosaurs is feather impressions in the rock…how do you know the coating was denser than on birds? This is pseudoscience at its finest, folks.
Bloggers and paleontologists, listen. I know you’re tired. You’re tired of people whining “Don’t take away my scaly raptors and replace them with foofy little peacocks with teeth!” I know you’re tired of creationists insisting that Microraptor was nothing more than a weird bird (I don’t even know that much anatomy, and even I can tell you that’s false). I know you specialize in the cutting edge discoveries of dinosaur paleontology, and a lack of feathers can be aggravating.
Nevertheless, seeing this aggravation bleeding out into long-winded rants about how important feathered dinosaurs are can get very tiresome. A raptor without feathers may be scientifically inaccurate, but it’s not a threat to scientific literacy. It’s just outdated. Don’t try saying “feathered dinosaurs are more beautiful,” either, because beauty is subjective, and some people just find a scaly raptor more badass. Too bad. Just because you have the benefit of scientific evidence doesn’t mean you can be a jerk to someone who likes scaly raptors better.
Eventually the public will come around and find feathered raptors “cool.” Don’t expect that to happen anytime soon, however, when you’re doing more whining than they are.
UPDATE: I would also like to point out, just for the heck of it, that many of the same anatomical features on Microraptor that identify it as a dinosaur (lack of a beak, teeth set into the jawbone, large antorbital fenestra, etc.) are traits shared by Archaeopteryx. For this reason, I place Archaeopteryx within the Dinosauria, rather than call it a full-fledged bird.
ADDITIONAL UPDATE: I think it’s more likely a given theropod was feathered if it was in a colder climate, such as the Antarctic Cryolophosaurus, Canadian Ornithomimids, or the Mongolian Tyrannosaur Yutyrannus. In warmer climates, they might simply not need them.
