Recent critical and extensive comparative studies of the Carboniferous faunas of the Rocky Mountain region have disclosed some facts that are of great interest to those who have become familiar with the Paleozoic fossils of the Mississippi valley. The Carboniferous faunas of the Continental Interior have now been well understood for over half a century. The faunas of the same geological age from the vast region west of the great central valley of the continent have also been well made out, but for the most part by a group of paleontologists entirely different from that group which was most familiar with the fossils of the Mississippi valley. On this account, chiefly, the faunas of the two regions have been treated largely independently and few exact correlative comparisons made.
