From The Economist via Science:
Many dinosaurs, perhaps even all of them, could have had feathers of some sort or another, the researchers suggest in a paper in this week’s Science. The feathers, they believe, might well have developed as a form of insulation and a way of signalling, perhaps to attract mates. It was only later that they were adopted for flight. At first that may have been for gliding. It is entirely possible, then, that even Tyrannosaurus rex sported the odd feather or two. Jurassic Park will never seem the same again.
