RE: bipedal lunges
I'd have to say that these charges being fatal is pretty much the
general idea behind them.
But I wasn't thinking of charges being used against other Triceratops',
more as a defence against predators. I fully agree that for intra
species fights, mating displays and such like, close quarters "horn
wrestling" is likely. The deer analogy here is quite apt.
However that cannot be their entire purpose, because then why would they
be pointed, and why have a shield behind them?
If you consider the speed and momentum available to a charging
triceratops, and a forward facing set of weapons, I think this points
very clearly to the charge being used as a tactic.
