Title: Re: T .rex Vision

How big were T .rex eyes? Or more important how big were their optic lobes?

The optic lobes themselves do not appear on endocasts - not because they weren't there, but because most nonavian dinosaur brains did not completely fill the brain cavity, and the lobes did not interact directly with the bones of the braincase.
