If they were anything like modern endothermic carnivores, they probably spent
a lot of time just lying about conserving energy. If they were more like
ectotherms, then even more so.
Also, an adult sauropod (whether hunted or scavenged) would go a long way.
Has anyone attempted to calculate the available soft tissue mass of an adult
sauropod (pick a relevant contemporaneous species), and assuming the likely
metabolic requirements of a predator, determined how long a single animal
would feed any single adult mega-theropod?
I suspect a single carcass would last quite a while, even for a group of
predators. Where tyrannosaurs are concerned, you'd have to include the
crunchier parts of the prey as well (since the blade-like teeth of
carcharodontosaurs would seem to restrict them to muscle and viscera).
