Tyrannosaurus rex

[Spalea]

I write "feathered t-rex" because it's hard for me to imagine them quite feathered. In the absence of absolute proofI prefer to write "a feathered t-rex". The climate during the Cretaceous had to be hot, hotter than now. Perhaps inside North America the nights could be fresh, but T-rex were rather huge weren't they ? IMO, the presence of feather is linked to the flight. OK ostrichs have plenty of feathers, but they are able to run very quickly, not the t-rex. And their legs and necks are featherless, why not the T-rexs' ?
