Yeah you're right. Most had feathers. Though it seems like the dragons in Flight Rising, kind of depict dragons. Though in real life, these dragons would never exist, they're too inefficient. Also the world works differently than it did many years ago, it was less focused on speed, and more on defense. So the strategy predators like lions and wolves use were more rare back then. Mostly being used by small predators, such as velociraptors. (Elephants only agree with your argument)
