Re: Lack of Running Giant Theropod Tracks

That makes sense -- would a big theropod have had to break out of a walk
to literally walk circles around a sauropod?
Tactical implications -- 1) a sauropod faced w/ a large-jawed tall biped
directly in it's path could not likely just ignore it and keep on
truckin'... the long skinny neck would require some sort of
rearing/turning behavior to defend.
2) carnivores generally can endure a much longer period of time w/out
nutrition than a large herbivore -- this combined with the sauropod's
need to protect the neck could make a 'persistence hunting' strategy
highly effective on a substrate that did not impede bipedal locomotion.
It might take 2 or 3 (e.g.) allosaurids a day or two to wear down a
loner sauropod, but they would not likely need to run to do it...
Seemingly ridiculous thought experiment -- put $1000 on the end of a
long pole (say, 3m) -- walk down a city street. Can you protect the
money w/out lifting the pole straight up in the air? No.
If you need to eat more or less constantly, how long can you hold the
pole up? Perhaps a day or two?
