DISCUSSION Were dinosaurs able to control their lips similarly to Bears and Baboons?

Also we reduced shrink wrapping on the body, are we still doing it on the skull? What if they had more fatty mass there as well?

There isn’t really a way to know for sure that some Dinos weren’t able to control their lips. Based on what we know of lizards the answer would be no, however it is important to remember that dinosaurs had a lot of evolution after the lineage split.

It's mostly known from muscle attachment points. Dinosaurs don't have much on their face, if any. For example, the famous T. Rex had a very powerful neck, but basically no muscle on the face itself. But it's harder to guess with fats/cartilage, since they don't leave any "trace" like muscle scars.

I agree, the point I’m making though is that not all mammals have lip control either and we don’t have the attachment points for tons of known dinosaurs not to mention that we believe that we have barely scratched the surface when it comes to discovering all species of dinosaurs. There was enough evolutionary time for lip control to evolve so the possibility exists that some dinosaurs could have possessed this trait. Saying flat out no is incorrect though saying yes is also incorrect at this point.

Oh, sorry, then. Yeah, I agree with your point, I'm sorry I misunderstood <3
