Was it only that? I think there was something a little more serious about
stratigraphy. If I remember correctl, someone noticed that pachy fossils very
rare and usually fragmentary, like if the beasts had not died at the same
place than other kinds of dinos. Hence the hypothesis that they may have lived
higher up, and that only the most resistent bits (those "solid heads") made it
to the lowlands, via mountain torrents. If this were true, pachy skulls
should display some distinctive wear, breakages and so on, right?
