The changing climate also led to increased ice at the poles, which would prove significant for the following epoch.
During this epoch, most of the world's landmasses reached their current locations, and the climate became significantly cooler and drier, allowing more grasses to grow and contributing to increased grasslands. Grazing mammals diversified, and increased migrations were possible because of the appearance of a land bridge connecting North and South America. The changing climate also led to increased ice at the poles, which would prove significant for the following epoch. For 10 points, name this geological epoch of the Cenozoic Era preceded by the Miocene, during the late portion of which glaciers began to advance, setting up the ice ages that would follow during the Pleistocene.
During this epoch, most of the world's landmasses reached their current locations, and the climate became significantly cooler and drier, allowing more grasses to grow and contributing to increased grasslands.
