Ruben, There is a huge literature on tyrannosaur osteology and anatomy, so you should easily be able to find descriptive papers and diagrams of the various bones of the skull. The image you attach is something from the web and it's a spinosaur, so a very different type of dinosaur than a tyrannosaur. Your best place to start is my 2012 monograph of the tyrannosaur Alioramus, in the American Museum Bulletin. You can download it free online.

Thanks Steven
The only diagrams I can seem to find to help understand the
characteristics listed in your paper is the one attached.=C2=A0 Obviously,<= br> the detail is much great than this.=C2=A0 characteristic 14, for example,r> discusses interdental plates and a deep lingual surface of premaxilla.
I'm using your paper for a thesis and would like to have a significant<= br> understanding of the characteristics your using to churn the data.=C2=A0 I&= #39;ve
look at the school library and it is not sufficient for this kind of
detail, so any suggestions would be appreciated (other than, don't use<= br> my paper and go away ;) )
The dental plate was significant to identifying Archaeopteryx as a
dinosaur so there should be a generalized idealized diagram somewhere.
