What purpose will the feather serve for the cold-blooded reptile's body?

Question

Recent findings in China revealed feathered dinosaur fossils which could be Evolution's missing link between reptiles and birds.What do you think?

Present-day reptiles are cold-blooded.Evidences why their "cousins" dinosaurs are cold-blooded?

Answer 1

The findings in China were indeed interesting, especially when the preservation of the fossils was discussed. There is also the theory that dinosaurs evolved from birds, confusing. Here is a site http://www.geocities.com/dannsdinosaurs/featdino.html that discusses that theory. There is also a discussion on what feathers may or may not be that is linked to that page. Here is the URL for that discussion:
http://www.geocities.com/dannsdinosaurs/whatfeat.html I found that page most interesting as it delves into the various uses and reasons for feathers.

Answer 2

the concept was put about by others a few years ago read the jurrasic park series of books but the feather is a natural insulator and light enough to shed water easily the hollow stems and the other parts are used for pillows and for the downy feathers near the body they are called down pillows and comforters for this reason they are used in cold winter countries to cover folkes from the cold rooms in barely heated rooms

Answer 3

I'm afraid your question is flawed. Theropods were almost certainly warm-blooded. Homeothermy appeared in the anscestors of the birds, not in birds themselves. Hence, insulating feathers certainly would have been beneficial before they were adapted for flight.

Answer 4

Well... birds are a reptile( reptiles gave rise to birds)!!! Feathers are modified scales
