Fran here, T-Rex is a tremendous faggot.

Dinosaurs confirmed for feathers. I see no feathers ITT. Pure sci-fi.

Ironical shitposting is still shitposting anon.
Fantastic, a new board and already there are dedicated shitposters. I'm truly impressed.

Not all of them had feathers dumbass.

Alright Jack Horner, go home.
You're theory is debunked.

No, all coelurosaurs did (or rather, all major groups within coelurosauria are known to have had feathers and there isn't any direct evidence for individual species didn't, although some might have been secondarily featherless). Besides that, there's a couple of ornithischian species (like Tianyulong and Psittacosaurus) with similar structures, but it is not known if they are analogous or homologous with coelurosaurian (proto)feathers. It could be that the common ancestor of crocodiles, pterosaurs and dinosaurs were fluffy (and that crocodiles and some dinosaurs lost theirs: crocodiles actually have some genes related to making feathers, all pterosaurs appear to have been covered with so-called pycnofibers and if that was the case, coelurosaurs and these species would have inherited them from the same ancestor) or it might be that body covering just evolved at least twice independently.

>at least twice
Three times, rather (pterosaur pycnofibers, coelurosaurian (proto)feathers, whatever the last common ancestor of Tianylong and Psittacosaurus had).
About crocodilian feather-making gene: http://ngm.nationalgeographic.com/2011/02/feathers/zimmer-text/4
>There's an even more astonishing possibility. The closest living relatives of birds, dinosaurs, and pterosaurs are crocodilians. Although these scaly beasts obviously do not have feathers today, the discovery of the same gene in alligators that is involved in building feathers in birds suggests that perhaps their ancestors did, 250 million years ago, before the lineages diverged. So perhaps the question to ask, say some scientists, is not how birds got their feathers, but how alligators lost theirs.
