The Idiots Guide Reptilian Braincase Anatomy

Dispite the title, I have no intention of explaining the anatomy of the reptilian braincase here. Rather, I would like to call for an idiots guide to it. I've been reading and re-reading Rieppel & Zaher's (2000) paper as well as papers on amphisbaenids, and gekkonids and their respecive brain cases. So far I have this to say: It's a small wonder that when a person achieves the supreme enlightenment of being able to understand this stuff in detail, his or her grey matter doesn't liquify and shoot out their eyes like science fair volcanoes.
The one solace that I have found is that someone else understands that this stuff is really complicated and has attempted to dumb it down to the level of your average, soon to be graduating, university biology student. The site Palaeos has a section specially dedicated to the braincase.
I don't know who wrote it, but whoever he or she was, that person is a genius; not so much for their clear understanding of the braincase, but because of such great lines as:
Braincase terminology is somewhat fractal. Each level of obscure anatomical referents turns out to be made up of parts and variants with even more eldritch anatomical names. Just as the essentially Greek braincase regions are made up of little Latin structures, there is probably an entire vocabulary of component substructures which is represented in Babylonian pictograms, the true meaning of which is revealed only to a secret hereditary caste of anatomical hierophants.
It seems to be one of those unwritten rules of paleontology that no one illustrates a mammaliform in occipital view.
While Bob is not a creature of towering intellectual prowess, we nonetheless value his companionship because of his congenial disposition and straightforward anatomy.
