text: The Pliocene, 5.3 to 2.6 million years ago, was a time of global cooling after
the warmer Miocene. The cooling and drying of the global environment may have contributed
to the enormous spread of grasslands and savannas during this time. The change in
vegetation undoubtedly was a major factor in the rise of long-legged grazers who came
to live in these areas.
Additionally, the Panamanian land-bridge between North and South America appeared
during the Pliocene, allowing migrations of plants and animals into new habitats.
Of even greater impact was the accumulation of ice at the poles, which would lead
to the extinction of most species living there, as well as the advance of glaciers
and ice ages of the Late Pliocene and the following Pleistocene.
