No it doesn't. There isn't any evidence for lips.

That is just a blog post and not a peer-reviewed scientific paper. Therefor it means absolutely nothing. You didn't present a single point.

It talks about how the fossil is not necessarily proving a lipless mouth as it could be other structures. Mark Witton himself is a very highly-regarded researcher.

...I guess just in my opinion, in makes more sense for lips as Crocodilians and birds have a very specific morphology and most tetrapods have them. You could do whatever you want. :/

Mark Witton is a very highly-regarded researcher, yes...on Pterosaurs. Not Tyrannosaurs.

Also to quote Carr himself. "It turns out, the rough wrinkly texture that dominates the face of tyrannosaurs is identical to what we see in crocodilians. So it doesn't match what we see in bird beats in doesn't match the smooth texture that we see on mammals it doesn't match the hunky bumpy texture we see in say lizards it looks just like crocodiles. Therefor the inference was that Tyrannosaurs had to have had  the same overlying integuments in order to produce this integuments of flat scales."
