Hi Ed,
You'll find lion skulls drawn from various perspectives in the following:

Pales, L., and C. Lambert. 1971. Atlas Ostéologique pour servir à l'identification des Mammifières du Quaternaire. I. Les membres. Carnivores. Paris: Editions du Centre National de la Recherche Scientifique.

Cheers,
Adam

Hi Everyone:

Could anyone direct me to an accurate high quality image of a line drawing of a lion skull with mandible?

Cheers,
