Sthenurines originated in the Miocene, diversified in the Pliocene, and radiated in the Quaternary to become one of Australia's most conspicuous mammal groups, the only lineage of browsing marsupials comparable in diversity to the browsing artiodactyl guilds of other continents. This title presents the analysis of sthenurines.

Describes forty-two fossil taxa recovered during a study of the San Timoteo Badlands that used magnetobiostratigraphy to develop a temporal framework for addressing the tectonic evolution of southern California over the last 6 million years.

Approximately 12 million years before the extinction of dinosaurs, a diverse terrestrial fauna inhabited what is now northcentral Montana. This title describes and evaluates the relationships of the large mammalian fauna of this area, which included rodent-like multituberculates, primitive therians, marsupials, and early eutherian mammals.

An Eocene (45 Ma) flora from Thunder Mountain caldera shows that montane conifer forest species from upper slopes descended to interfinger with mixed conifer-deciduous hardwood forest on the caldera floor then near 1700m. Most species are allied to those in the USA, but a few genera are in China.

Oligocene Haynes Creek flora of Eastern Idaho of 70 species is dominated by deciduous trees, many with descendants in China. Comparison with the Horse Prairie flora, 30 miles east and across the present continental divide, indicates that the divide was then low and discontinuous, with warmer climate to the east.

A study of the Miocene Carmel flora of California, an evergreen laurel-oak forest that grew in a mild temperate, frost-free climate, with annual precipitation of about 760mm.
