Done this back in 2017 for a paper describing tooth marks on a Centrosaurus skull belonging to a juvenile gorgosaurus by David W.E. Hone, Darren H. Tanke, and Caleb M. Brown
you can see the paper and my artwork here => https://peerj.com/articles/5748/
This is a second picture that was scraped later on and wasnt used for the paper. Same as the first one, the anatomy might look wonky as i did not develop my style quite yet, but again i am still happy with it.
