The Miocene is a geological epoch that spanned from roughly 24 million years ago to about million years ago (after the Oligocene epoch and before the Pliocene period). During this period much of the continental Earth formed. Global warming occurred during the middle Miocene.

A Pliocene flora from the Mount Eden beds, southern California, by D.I. Axelrod The Deschutes flora of eastern Oregon, by R.W. Chaney The San Pablo flora of west central California, by Carlton Condit. were a few notable trends in mammalian evolution during the Miocene epoch.

The prehistoric horses of North America took advantage of the spread of open grasslands and began to evolve toward their modern form; transitional genera included Hypohippus, Merychippus and Hipparion (oddly enough, Miohippus, the "Miocene horse," actually lived during the Oligocene epoch!).

Primate - Primate - Miocene: The Miocene Epoch (23 million to million years ago) is probably the most fruitful for paleoprimatology. During this time, dramatic changes in geomorphology, climate, and vegetation took place.

The Miocene was a period of volcanism and mountain building, during which the topography of the modern world was becoming established. Important Miocene deposits occur in North and South America, southern Europe, India, Mongolia, East Africa, and marine and terrestrial environments are represented in the Miocene stratigraphic record.

The record of terrestrial life is extensive and varied, providing a rather complete view of the development of vertebrates, especially mammals.

Miocene Epoch ( mya) Early in the Miocene, temperatures begin to rise. Extensive mountain building in the Americas and Asia alters air circulation and weather patterns, contributing to drier.

In western Wyoming, Barnosky () recognizes xeric shrub floras during the latest Miocene. The Mt. Eden flora in southern California suggests the beginning of steppe conditions (Wolfe, ). Axelrod's () floristic review shows that in the Great Basin and the midcontinent, the most arid interval of the Tertiary occurred at about 6 Ma.
