You may call a jay a bird. Well, so he is, in a measure--because he's got feathers on him, and don't belong to no church, perhaps;but otherwise he is just as much a human as you be. And I'll tell you for why. A jay's gifts and instincts, and feelings, and interests, cover the whole ground. A jay hasn't got any more principle than a Congressman.
Paleontologists have tried to turn Archaeopteryx into an earth-bound, feathered dinosaur. But it's not. It is a bird, a perching bird. And no amount of 'paleobabble' is going to change that.
Instead of regarding birds as deriving from dinosaurs, Scansoriopteryx reinstates the validity of regarding them as a separate class uniquely avian and non-dinosaurian.
