Note 9 — Chapter III · FOSSIL PEDIGREES

Thus, to explain away “wrong sequences” of fossils, Heim and Rothpletz postulate the great Glaurus overthrust in the Alps, Geikie the great overthrust in Scotland, McConnell, Campbell, and Willis a great overthrust along the eastern front of the Rockies in Montana and Alberta, while Hayes recognizes numerous overthrusts in the southern Appalachians. “The deciphering of such great displacements,” says Pirrson, speaking of thrust faults, “is one of the greatest triumphs of modern geological research.” (“Textbook of Geology,” 1920, I, p. 367.) Desperate measures are evidently justifiable, when it is a question of saving the time-value of fossils!
