>>4999675Were it gets wider is the back of the jaw. The lower front of the jaw isn't as wide. That is what a lot of Tyrannosaurus Rex skulls look like, and of course the muscle will change the shape of the head somewhat, but that is how some T. Rex heads and jaws would had looked like in the flesh. It is a good depiction. OP's pic and my pic are the same, except OP's has flesh on it
The width of an Tyrannosaurus Rex skull will vary. It depends on the subspecies and individual, and sexual dimorphism might play a factor too but no one knows that for sure. Obviously, the width of the skull broadens with age, it's an adult trait. So the expression of that trait will vary. You do see many Rex skulls exactly like that. You have to keep in mind also that the bones can warp before they become completely fossilised
Here is a 3D model of a real specimen, as another example: https://sketchfab.com/3d-models/tyrannosaurus-rex-nhmw-geo-1998z00490001-816d1a0d27e146669f09e6fc2d260dc7
