The Oligocene Haynes Creek Flora of Eastern Idaho (UC Publications in Geological Sciences)

This flora of 70 species is dominated by deciduous trees, many with descendants in China. Precipitation was 890 mm, mean annual temperature 12.5C, the annual range 10C, and freezing rare. Elevation was about 1000 meters. Comparison with the Horse Prairie flora, 30 miles east and across the present c...

The Middle Miocene Pyramid Flora of Western Nevada (UC Publications in Geological Sciences)

The Pyramid flora (15.8 m. years) is wholly dominated by broadleaved deciduous hardwoods of eastern alliance that indicate ample summer rain. Deciduous hardwoods are largely absent from slightly younger nearby floras (less than 15.8 m. years) that are dominated by mixed conifer and broadleaved everg...

The Early Miocene Buffalo Canyon Flora of Western Nevada (UC Publications in Geological Sciences)

The Buffalo Canyon flora of 69 species, 18 MA old, from semiarid western Nevada, is a rich mixed conifer-hardwood forest with evergreen sclerophyll vegetation on bordering volcanic slopes. Precipitation totalled 100 centimeters and fell chiefly in summer; winter snow was light. Elevation was 1,280 m...

The Eocene Thunder Mountain Flora of Central Idaho (UC Publications in Geological Sciences)

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 1700 m. Most species are allied to those in the western United States, but a few gene...

A Miocene (10-12 Ma) Evergreen Laurel-Oak Forest from Carmel Valley, California

This is a study of the Miocene Carmel flora of California, an evergreen laurel–oak forest that grew in a mild temperate (mean annual temperature of 15 degrees C), frost-free climate, with annual precipitation of about 760 mm (30 in.). Collectively, the Carmel and other Miocene floras like the San Pa...
