Robin always thought that T. Rex was a scavenger, because he would have been catastrophically inferior in duels with potential prey. Now he has seen a documentary, there it is assumed that he hunted in packs, like wolves or lions. That changes the basic assumption completely. A triceratops might have been able to cope with one, but with several at once, that was probably it for the poor animal.
Moreover, tyrannosaurs had rather large brains, so they were quite intelligent. Robin suspects they must have had their own language, names and an alpha.
“It’s about time these animals were bred again!”
We think so, too.
