of both. Quite capable of hunting it's own food, but not averse to
scavenging if it's easy meat.
Seems highly likely, as this is true of most meat-eaters. Apart from
vultures and the Tasmanian devil, I can't think of any extant carnivore
that is primarily a carrion-eater. Even the much-maligned hyena kills
most of its own food, except in the rare case that they're outnumbered
by lions to freeload from (it's usually the reverse). Most meat-eaters
would be full-time scavengers if possible, just as most humans would
prefer to get free groceries rather than have to work for them... but
there's seldom a free lunch.
So none of today's beasts approach T. rex in size... but even if it
couldn't run, that doesn't preclude it from being a highly-effective
ambush predator - much like crocodilians and the Komodo dragon, today's
closest analogs to the Tyrannosaurus. If you were gonna take down a
Triceratops, you'd really want to do it from behind. Horner cites T.
rex's probable keen sense of smell as evidence of scavengry, but
there's good reason why an ambush-attacker would benefit greatly from
The "Either/Or" mentality in palaeontology really annoys me sometimes!
For sure. Dinos must have been more than the superficial stereotypes
they're commonly portrayed as.
