The road to Spinosaurus I: Megalosaur skulls

A few years back I wrote a couple of essays about Spinosaurus, on what could be said about the proportions and habitat of Spinosaurus. Ultimately I decided I would have to work from the ground up to create a new skeletal. Today I want to start laying out my thoughts on this challenging topic. Starting phylogenetically broadly and working towards El Spino, here is a quick look at the proportions of megalosaur skulls…
