Paleontologists usually restrict dinosaur behavior to things they can observe in modern reptiles. Besides the fact they weren't exactly the kind of reptiles we have available at present, I subscribe to the 800-lb gorilla philosophy: once you get really big, you can pretty much have whatever behavior you like.
In spite of that, I dug up this little tidbit on reptile behavior that might explain multiple adults:
"The Chuckawalla, Sauromalus obesus (Berry, 1971) is the only lizard known to have harems. In this species, large tyrant males defend large territories within which good-sized but subordinate males are restricted by the tyrant's action to mini-territories about rock piles and basking sites. Females have feeding and basking site territories generally larger in area than those of the subordinate males. Tyrants patrol their territories daily, restricting the activities of subordinate males and visiting the females within their territory. Patrolling occurs before, during, and after the breeding season. Only the tyrant mates with the females, but most mating is initiated by the female (Berry, 1971)."
-- apropos of this particular discussion, I like the use of the word "tyrant"
While I was poking around, I stumbled into a Nat'l Geographic website that claimed the top T.rex speed was 12 MPH.
"Which you could outrun..."
12MPH is a 5min mile. Can *YOU* run that fast?
Average jogging 8MPH
Average marathon running 8.8MPH
Average running (peak condition) 10-15MPH (as long as the adrenalin lasts)
