I am a bit confused now. You are saying that I am correct that Brand has
more recently written that the tracks could also be consistent with
having been laid down on wet, but not underwater, sand? Yet you also
said that Brand's work was "conclusive" and that "the data require that
the environment be completely subaqueous". Did I miss something, or did
you just misunderstand the question and intend to say that I was
incorrect?
