New Artiodactyls from the Oligocene and Lower Miocene of Nebraska
Cook HJ. 1934. New Artiodactyls from the Oligocene and Lower Miocene of Nebraska. The American Midland Naturalist. 15(2):148-165
During the past twenty-five years, the writer has accumulated fossil Artiodactyls from the many Oligocene and Lower Miocene exposures of northwestern Nebraska. Many of these were given field records, but until recently were neither catalogued nor studied. Yet they contain both new occurrences and new taxonomic groups, which extend the reported range of certain races both downward into the Lower Oligocene, and upward through distinct formations into the Lower Miocene beds. In addition, certain new forms of the Middle Oligocene are recognized, along with many specimens of known species, which are not discussed in this paper. While some of these types are less complete than we could wish, it seems important to describe them at this time, in order to extend our available records of these rare forms, of which types are preserved in the Cook Museum of Natural History, Agate, Nebraska. All specimens described in this paper were found by the writer unless otherwise noted.
