I was reading about Tarbosaurs this morning and how apparently juveniles were small sleek predators while their parents were huge intimidating mega-carnivores. So they probably didn't come into conflict much because they operated in separate distinct ecological niches. I doubt very much that they brushed their teeth, so their breath ( juvenile and adult ) must have stank beyond belief of rotting carrion.
