The Rise of the Mammals: The Paleocene and Eocene Periodsby Thom Holmes
The Rise of Mammals unravels the early evolution of mammals and birds that were survivors of the Mesozoic Era. The pattern of bird and mammal evolution prior to the Cenozoic Era is recounted, as is the story of the critical first 10-million-year span of the Cenozoic Era known as the Paleocene Epoch. This book describes the epoch as a time of recovery for mammals and birds, followed by their rapid adaptation to new ecological conditions. The Rise of Mammals also explains how Earth continued to change as the continents drifted farther apart, and how this period was a time of evolutionary experiments. The conclusion discusses how, by the end of the Paleocene, the roots of most modern birds and mammal families had been set, forging a series of divergent and specialized paths that continue to diverge some 55 million years later.
