I adore feathered dinosaurs. It feels a little strange to say that, but it’s true. Few things make me happier than seeing delicately-rendered restorations of theropods covered in fuzz and ceratopsians with some accessory bristles. The various bits of plumage–from quill-like structures to true feathers–make dinosaurs look even more wonderful and fantastic than the drab, scaly monsters I grew up with. And who wouldn’t love a fluffy like dinosaur like Sciurumimus, perhaps the cutest dinosaur of all time?
Of course, not everyone feels the same way. There are some people who want their dinosaurs to be scaly, scaly, scaly, science be damned. They weep, wail and gnash their teeth whenever a new study suggests that another branch of the dinosaur family tree might have been adorned with plumage. It’s as if they expect the Dinosauria to be consistent with an unchanging canon–sci-fi and comic fans suffer a similar apoplexy when one of their favorite characters deviates from their most cherished storyline.
io9′s “We Come From the Future” show recently debated whether science had “ruined” dinosaurs by decorating so many non-avian species with feathers. (Remember–birds are dinosaurs, too, and there have been some very scary birds in the history of life on earth). Granted, some restorations of feathery dinosaurs really do look stupid, and the minor plumes on the heads of Jurassic Park III‘s Velociraptor didn’t really help.
The show’s point-counterpoint debate on the matter isn’t totally serious, and it’s a way to get a tidbit of science out to a wider audience. That’s a good thing. All the same, I’m pretty sick of people who complain that feathers somehow detract from dinosaurian magnificence. How immature can you get? We all love the dinosaurs we first meet as kids, and, for many of us, those leviathans were drab and scaly. But those earlier versions have been slit from stem to stern by more active, colorful and complex dinosaurs, many of which had some kind of feather-like body covering. Which would you prefer? The scaly, sluggish pot-bellied Tyrannosaurus of the mid-20th century, or a svelte, agile predator that has a few patches of fuzz?
Don’t misunderstand me here. I’m not saying that all dinosaurs looked like big chickens. Dinosaurs exhibited an array of body structures–from simple, fuzzy tubes to bristles and full-on flight feathers. Some species, like modern birds, even exhibited several different types of feathers. The weird Beipiaosaurus, for one, had fuzzy protofeathers on much of its body but also had a sort of tail fan created by a different feather type. And “feathered dinosaur” doesn’t mean that the animal was entirely cloaked in plumage. Take Psittacosaurus, for example–this little ceratopsian was a very, very distant relative of birds and had a row of bristles along its tail. The structures were probably visual signals, and I have no doubt that same was true among other dinosaurs. Feathers aren’t just about flight or insulation, but they’re also important in display and communication.
And feathers are the key to dinosaur color. I’m still awestruck that we can recreate the colors of creatures that have been extinct for tens of millions of years. By comparing the microscopic details of prehistoric dinosaur feathers to the feathers of modern birds, we can finally answer that most persistent of paleo questions. That fact, alone, makes feathered dinosaurs especially magnificent.
I’m weary of this Portlandia-esque attitude that dinosaurs are over if they’re feathered. Please. New scientific discoveries are allowing us to gain unprecedented insights into the biology of dinosaurs, including the lives of the fluffy species. Feathers are just part of that bigger picture, and I’m ecstatic that paleontologists are reconstructing dinosaurs in ever-greater detail. The point is this. Feathered dinosaurs are awesome. Deal with it.
