If they know that the gallinoansera clade had already emerged before the K-T extinction, they most likely also know about birds being dinosaurs. Specifying “non-avian” everytime is a pain and saying “K-T extinction” is not understood by all, no need to correct them for semantics when their wording gets the point across.
Debatable, but the common consensus is that T-Rex had little to no feather. At the very least, the feathers couldn’t have covered all of the body because T-Rex skin imprints have been found without feathers, tho they’re not of all the skin, so there still may have been some feathered parts.
The idea that T-Rex had feathers didn’t come from nowhere tho : We have many evidence of feathered dinosaurs from many groups. The T-Rex is niched within the coelurosauria clade, which includes many dinosaurs that are mostly covered in feathers (and even modern birds). There’s even a close relative of T-Rex, Yutyrannus, with evidence of wide feather covering.
The reason why T-Rex didn’t have that much feathers is likely the same reason why elephants aren’t hairy : Big animals have less problem keeping heat, and may even at some point have problem evacuating excess heat (and yes, many dinosaurs were warm blooded). So as T-Rex got bigger, feathers became more of a hindrance.
And there I thought it was a smartass joke because you had switched “picture” for “language” only once and that it just meant the text of both lictures were written in the same language…

Is this a staged joke? Is everyone here in some conspiracy to make me believe that either the world went mad or I did? Why is everyone calling every Marvel movie “peak” but the first Iron Man? Obviously, this was the best one.
