The Miocene (/ ˈmaɪ.əsiːn, - oʊ -/ MY-ə-seen, -⁠oh-) [6][7] is the first geological epoch of the Neogene Period and extends from about 23.03 to 5.333 million years ago (Ma).

Feb 21, 2025 · Miocene Epoch, earliest major worldwide division of the Neogene Period (23 million to 2.6 million years ago) that extended from 23 million to 5.3 million years ago, a time when land-dwelling mammals were essentially modern.

The Miocene Epoch, 23.03 to 5.3 million years ago,* was a time of warmer global climates than those in the preceeding Oligocene or the following Pliocene and it's notable in that two major ecosystems made their first appearances: kelp forests and grasslands.

Miocene Epoch, Major division of the Neogene Period, from 23 million to 5.3 million years ago. The extensive fossil record of terrestrial life during the Miocene provides a fairly complete picture of the development of vertebrates, especially mammals.

In the Neogene Period, Miocene is the first geological period, this extends approximately from 23.03 to 5.333 million years ago. The name ‘Miocene’ was given by Charles Lyell, a Scottish author.

Aug 6, 2023 · The Miocene epoch, a significant period in Earth's history, extended from about 23 million to 5.3 million years ago. Characterized by drastic climate changes, the rise of new mammalian species, and the formation of new landscapes, the Miocene has left an indelible imprint on the planet.

May 5, 2014 · The Miocene is the first geological epoch of the Neogene period and extends from about 23.03 to 5.332 million years ago (Ma). The Miocene was named by Sir Charles Lyell. Its name comes from the Greek words μείων (meiōn, “less”) and καινός (kainos, “new”) and means “less recent” because it has 18% fewer modern sea invertebrates than the Pliocene.

The Miocene epoch is a major division of the geologic timescale and the first epoch of the Neogene period of the Cenozoic era (or the fourth epoch of the Tertiary sub-era). The Miocene follows the Oligocene epoch and is followed by the Pliocene epoch.

The Early Miocene (also known as Lower Miocene) is a sub-epoch of the Miocene Epoch made up of two stages: the Aquitanian and Burdigalian stages. [2] [3] The sub-epoch lasted from 23.03 ± 0.05 Ma to 15.97 ± 0.05 Ma (million years ago). It was preceded by the Oligocene epoch. As the climate started to get cooler, the landscape started to change.

The Miocene Epoch 23.8 to 5.3 mya. At right is pictured (in front), Chalicotherium, a Miocene mammal from Kazakhstan. Chalicotherium was an unusual "odd-toed hoofed mammal, or perissodactyl.Both the perissodactyls and artiodactyls underwent a period of rapid evolution during the Miocene.. The Miocene was a time of warmer global climates than those in the preceeding Oligocene, or the following ...
