that's selection bias. only the avian 'dinosaurs' survived, but calling them dinosaurs would be like calling humans rodents. It's not like birds existed back then.
There seems to be a rush to try and put feathers on everything. We are finding some amazing specimens that are giving us amazing detail, such as the ankylosaur found in Canada. Yup, covered in scales and hard armor.
Now we got this T-rex crazed idea to put feathers all over them. It sort of reminds me of the 1990s who tried to put t-rex as scavengers / non predators because of 1 solitary data point. the data strongly suggests they were scaled (we found skin impressions of t-rex, they had scales). So now they are trying to say 'oh well maybe they had feathers elsewhere, or were covered in feathers when young'. sheesh.

if a leaf can be fossilized, I imagine so can a feather.
