  With all due respect, however, Jack Horner is essentially correct in the
quote above, even if the underlying premise may not be. Yes, a largely
predaceous ancestor, like the non-tyrannosaurine tyrannosaurids like
*Gorgosaurus*, with highly binocular vision and a more active predatory
lifestyle, CAN give rise to a more opportunistic, scavengerial descendant.
Whether this is the case is based on other data, which has been presented
elsewhere (and so far nearly ALL data points to an active predatory regime,
just not a fast one).
