existence of all the forms of animals below him. The last great division of time is called Cenozoic.<20> This means new life forms. In this age, the forms of life are much nearer our own. As it was some time during this epoch when man makes his appearance, we deem it best to go into more detail, and give the subdivisions of this period. It has been amply sufficient to give simply the outlines of the other periods. In order to fix more clearly the sequence of life, we will give an outline showing the periods we have reviewed, and also the subdivisions of the Cenozoic time, which we are now to examine with more care. OUTLINE. LIFE. Archaean Time. The Beginning: Includes the long lapse of time when the globe could not support life, but towards its close faint traces of life, both animal and vegetable appeared. Paleozoic Time. The Period of Old Life Forms: Forests of flowerless trees; but pines grew in the coal measures. Animal life largely invertebrate; but amphibians and reptiles among the vertebrate appear at the close. Mesozoic Time. The Period of Middle Life Forms: Flowering trees increasing in |
