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).

Apr 3, 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.

The Miocene is the last and final epoch of the first Neogene period and the fourth of the Cainozoic. It started about 23 million years ago and ended about 5.33 million years ago. The rock beds that mark the start and end are well known, but the exact dates of the start and end of the period are uncertain. The Miocene was named by Charles Lyell.

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 Miocene extends from about 23.03 to 5.332 million years before the present.

The Miocene begins with a gradual, short-lived warming, and some tropical forests expand. Drying accompanies this temperature change, and tough scrub plants evolve as a new form of vegetation.

Dec 23, 2020 · Here, we review the state-of-the-art in Miocene climate, ocean circulation, biogeochemical cycling, ice sheet dynamics, and biotic adaptation research as inferred through proxy observations and modeling studies.

In the Miocene Era, specific animals and plants thrived to grow in the land. We will learn about the era, its vegetation, and animal life in detail in our prevailing section. Miocene Age. Miocene time, which is also known as the Miocene Epoch marks the earliest major worldwide division of the Neogene period which is about 23 to 2.6 million ...
