Ammonoids occur abundantly within Cisuralian strata at Beck Springs, Buck Mountain, Nevada. The genus Uraloceras has been recovered from a micritic concretionary interval deposited within a tectonically initiated sub-basin of the Cisuralian Dry Mountain Trough.

Ammonoids occur abundantly within Cisuralian strata at Beck Springs, Buck Mountain, Nevada. The genus Uraloceras has been recovered from a micritic concretionary interval deposited within a tectonically initiated sub-basin of the Cisuralian Dry Mountain Trough. The abundant and diverse fauna at Beck Springs, Buck Mountain contain faunal elements characteristic of a transitional paleobiogeographic association, which includes "Boreal", equatorial, cosmopolitan, and endemic forms. Endemism may have been associated with paleogeographic isolation of basins and sub-basins on the western margin of Northern Pangaea. Uraloceras is biostratigraphically restricted to Sakmarian through early Kungurian of northern Pangaea and further restricted to Artinskian strata in North America.
