When a part of an animal evolves some kind of offensive purpose, it usually is
for intraspecies combat first. Since the clubs could do considerable damage, I
suspect that they were used in display behavior, so that the likelyhood of them
actually coming to blows would be rare. Granted, the tails certainly could've
been used to break the knees of a predator, but this is a secondary function.
