Hyperodapedon (notice description)

I have not much time today, large commission deadline comes closer, but I wanted to share with you this sketch of 
an rhynchosaur. This quick pic was produced because of an recent study by Alan et al. about soft tissue preservation and bone marks in rhynchosaurs. As they 
showed the large frontal teeth many of these strange reptiles had, were most likely covered by lizard like lips, but as the authors proposed it's possible that these animals had more in common with some mammals in terms of facial mobility. 
I thought here a bit further and speculated about possible behaviors, like this "lip flick" which is maybe best known from some baboons like the Gelada. 
In addition I played here a bit with the color of the teeth, I had a nutria in mind.

Edit: As I just realized these are not teeth but just bones, rhynchosaurs had no incisors...

Edit: I just realized I'm to good at lying, because this is to 80% just a April's fool  , there is no recent paper about rhynchosaur soft tissue (unfortunately) and while I think it's pretty plausible that these animals could have lizard like lips, it's pretty unlikely that Hyperodapedon was able to move its upper lip like a mammal (but I like the idea non the less).
