In the Mammalian Age, -whieli includes the Tertiary and Quaternary Periods, the vegetation is de- cidedly more modern than in the preceding. In the Tertiary Period nearly all the genera of the Palms, Grasses, and Dicotyledones (Fig. 347) were the same as now, though most of the species are extinct. The Diatoms, too, existed in great abundance ; and immense deposits, con- sisting wholly of their silicious shells or valves (frustules), are found in the Tertiary Period. The celebrated Bohe- mian deposit in Europe is fourteen feet thick, and Ehren- berg estimated that every cubic inch of the material contains forty billion shells. The Rich- mond deposit in Virginia is thirty feet thick, and many miles in extent. The Mosses (Bryophyta) and the Protophyta very likely existed before this time, but they have not been found in rocks lower than the Tertiary. In the Quaternary Period the plants were almost wholly identical with those now -living. In this period, too, man is supposed to have appeared on the earth. 206. The Age of Man, or the present time, exhibits a vegetation of a higher type than the preceding ages, and the species are exceedingly numerous. All countries are Fig. 347.
