Fossil evidence from Mesozoic feathered dinosaurs and early birds indicates that certain dinosaur species underwent feather molting processes, although strategies like sequential molting differed from modern birds.
The retrieved papers consistently support the claim that certain dinosaur species underwent molting. Papers [0], [1], and [2] all discuss evidence of feather molt or moult in non-avian dinosaurs and early stem birds such as Microraptor and Confuciusornithiformes, while paper [3] is tangential developmental biology. The evidence is robust and directly supports the claim.
