Title: "re: T. rex and other large carnosaurs"

"Carnosauria" is paraphyletic, and should not be used. Megalosaurus = Torvosaurus (on the basis of the extensive, thoroughly described/illustrated hypodigm of the former I am about to publish, the latter cannot be separated from Megalosaurus Buckland 1824).

What are you using as the Megalosaurus type? What synapomorphies are you using? Have you looked at the specimens of both Torvosaurus and Megalosaurus?
