I might counter this by saying that maybe the younger tyrannosaurs are just
doing what comes naturally (chasing after prey) and it was instead the older
adults that learned to take advantage of an ambush strategy in conjunction
with the chase. The youths would then be able to learn the ambush aspects of
the hunting strategy by observation and the adults would not need to teach
the youths how to chase after prey, since that part would come naturally to
them anyway....
