To which email@example.com answered :
It's incredibly hard to knock down trees by a sudden impact because in
addition to being strong, they are resilient (in the sense of
elastic). I don't believe even the largest pachies could have done
this to any tree they couldn't more easily have pushed over by
sustained application of body-weight.
OK, I might have been too dreamy, but these domes had a fuction, whatever it
was. If not to knock down trees (a hypothesis which I realize now is silly),
then what for? Apparently, there's no scars, no marks indicating they could
have used them in fights. Even Stego's plates have a supposed (and most
probably true) protective function. So what about the thickness of their dome?
