On that whole T. rex wimp/supercarnivore dialectic:
This has probably been brought up before, but... Aren't most
vultures unable to smell things (or at least well)? From what I've read,
most vultures hunt by sight, not smell. Doesn't that kinda debunk the whole
olfactory lobe-based analogy? Just idle, pre-coffee morning thoughts...
