The Middle Miocene is a sub-epoch of the Miocene epoch made up of two stages: the Langhian and Serravallian stages.
During this period, a sharp drop in global temperatures took place.
This event is known as the Middle Miocene Climatic Transition.
For the purpose of establishing European land mammal ages, this sub-epoch is equivalent to the Astaracian age.
