Isn't this Carcharocles now? Or does it keep flip-flopping back and
forth (the genus, that is, not the shark itself).

Plants don't run away or require subduing. If a sauropod had to chase
down its food it would probably have starved.
A super-large theropod that specialised only on slow-moving sauropods
would still have to have been agile enough to avoid the herbivore's own
defences. Unless it developed a means of sauropod hypnotism, kind of
like a ten tonne Count Dracula. :)
