North American Devonian conodont biostratigraphy North American Devonian conodont biostratigraphy
The Lower Devonian of Nevada provides a reference sequence of nine conodont faunas, five of which are also at Royal Creek, Yukon Territory. The first appearance of Icriodus woschmidti is comparable to that in the lower Gedinnian in Europe; the Polygnathus dehiscens- P. foveolatus lineage correlates with the Emsian. Directly associated graptolite and brachiopod zones in Nevada date the...

Devonian of the Northern Rocky Mountains and plains Devonian of the Northern Rocky Mountains and plains
The Devonian System, represented predominantly by shallow-water marine carbonate, is widespread in Montana, Wyoming, eastern Idaho, North Dakota, South Dakota, and northwestern Nebraska. It comprises cratonic rocks in the east and miogeosynclinal rocks in the west. The cratonic rocks thicken generally northward from their southern limit in Wyoming across a broad shelf that occupies most...
