Not that it matters but on the Paleo thread Television User has posted on the new paper (which got the usual shitload of ill informed publicity) stating T.rex may have not had feathers.
I think it is flawed for all sorts of reasons which is why I did not post the many links on here in the snug.
Absence of evidence is not evidence of absence.
That means just because we haven’t found feathers preserved on big tyrannosaurids, does not mean they didn’t have them. The conditions needed for feather preservation are very specific (like for the nine metre Tyrannosaurid fluffball Yutyrannus), and the places where we find these big tyrannosaurids are not the same types of places that preserve feathers.
Big Archosaurs were not like big mammals - they were far more efficient and the paper even states that rex et al may have just had plumage on certain areas.
So I believe rexy had feathers and they just weren’t preserved. Maybe it had feathers as a baby and lost most of them as an adult. Maybe it had feathers in some places on its body.
Nice diagram showing the possibilities.

Way off topic but I would have posted on there.
Sorry.

This enormous animal turned up on a GreenTracks herp trip in the Peruvian Amazon. The body was found floating in a river. With some of the tail missing it still measured 5.3 meters (17.38 feet).
Here is the skull (it measured 31 inches in length).
I like the idea that somewhere out in the Amazon, massive fully mature Black Caiman still prowl the waterways and haven't all been exterminated.

I always thought of Caiman's as tiny Crocodilians.
