    Zach, basically with the publication of this paper:

    Frey, E., Tischlinger, H., Buchy, M.-C., and Martill, D. M. 2003. New specimens of Pterosauria (Reptilia) with soft parts with implications for pterosaurian anatomy and locomotion. Pp. 233-266 in: Buffetaut, E. and Mazin, J.-M., eds. Evolution and Palaeobiology of Pterosaurs. Geological Society Special Publications 217. Geological Society of London.

    Which describes this specimen of Pterodactylus: http://www.pterosaurier.de/pterodactylus_sp_01_o.jpg

    If you direct your eyes to the black manganese oxide spot at the back of the skull, you’ll notice a dorsally curving conical structure extending off the back of the skull. This is called the occipital cone and forms the back of the crest. Beginning at the posterior margin of the naof you can see the remains of the medial crest, those two brown patches of skin. These are in direct contact with a row of fibers that extend along the dorsal margin of the skull to the occiput. The occipital cone was discovered back in the 70’s in another large specimen of Pterodactylus by Wellnhofer, but mostly ignored till this paper.
