Why do we now believe dinosaurs had feathers?

Question

Why do we now believe most/all dinosaurs have feathers? Is it simply that we found fossilized feathers and hence assume all dinosaurs had feathers?

Thanks!

We don’t believe that, we know that. Fossilized feathers together with fossil dinosaurs have been found. Scientists do not assume that *all* dinosaurs had feathers. But many dinosaurs did have feathers, like chickens and turkeys and other birds do.
