The issue is one of required rates. At the vultures low search costs, it
can get by on meager pickings. A T. rex, with its higher search *requires*
more just to get by.
This difference in the break-even point is the key problem with a primarily
scavenging T. rex. The cost/benefit ratio for ground scavenging is too
high for T. rex to be able to rely on that source.
