Book excerpt: Excerpt from Contributions to the Geology of Kentucky Such is the result of the comparison we have made; from which it appears, that a decided analogy exists between the fossils of the upper beds of the Falls, and those of the Devo nian strata of Europe, and that there are sufficient grounds for referring them to that geological epoch. We may next compare the species contained in the west ern Silurian and Devonian strata with their representatives in New York. The first table at the end of this article shows thirty-one spe cies occurring here, which may be considered as identical with New York forms. Of these it will be seen that the Clinton group is represent= ted by two species, the Niagara group by six, the Onon daga limestone by five, the Corniferous limestone by nine, the Hamilton group by eight, and the Genessee slate by two; while from the above comparison, the following formations occurring in New York, above the Clinton group, appear to have no representatives in the western States; namely: the Onondaga slate and water-lime groups, the Pentamerus lime stone, the Delthyris shaly limestone, Oriskany sandstone, Marcellus shale, Tully limestone, and the Portage and Che mung groups. The fossils in our strata, of which we have spoken, correspond precisely in the order of their superposition with those of New York.
