This has long been my main reason for rejecting the idea of a
primarily scavenging T. rex.
Now Quetzalcoatlus is another matter entirely!
With its long wingspan, and giant size, it seems closer to
a condor than to any other animal I can think of. [And, for
those of you who do not know this, a condor is simply an
extremely large vulture].

With T. rex's hind legs, I think this may well be quite important.

Of course I just call such an animal a predator, since opportunistic
scavenging the the *norm* in large predators, and is not a sufficient
indicator to justify a different term.
The peace of God be with you.
