Apparently, larger theropods probably lacked feathers because it would have led their body to overheat (unless they lived in cold regions, like Yutyrannus). Now large dromeosaurs like Utahraptors were larger than a polar bear while living in an environment that was the exact opposite of the north pole climate wise. So isn't it possible they were featherless/sparsely feathered too?
