The Age of Mammals The Oligocene and Miocene Epochs by Thom Holmes


The Age of Mammals The Oligocene and Miocene Epochs by Thom Holmes

About 15 million years ago, the diversity of mammals worldwide reached an astounding peak. As the continental landmasses shifted and temperate climates encouraged flowering plants, woodlands, and grasses to grow in abundance, mammals stepped into ecological niches left vacant by the extinction of the dinosaurs. The Oligocene and Miocene epochs saw the foundations of modern-day mammal groups. Adaptations of the jaw, teeth, skull, limbs, and other traits led to mammals that were better adapted for every mode of life. The Age of Mammals explains how mammals and birds increased their collective footprint to dominate the Earth, and how they evolved to present-day form.
