The Miocene (/ ˈ m aɪ. ə s iː n,-oʊ-/ MY-ə-seen, -oh-) [6] [7] is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words μείων (meíōn, "less") and καινός (kainós, "new") [8] [9] and means "less recent" because it has 18% fewer modern marine invertebrates ...
Based on the magnetic susceptibility of Miocene sedimentary stratigraphic sequences in the Huatugou section in the Qaidam Basin, the MMCO lasted from 17.5 to 14.5 Ma; rocks deposited during this interval have a high magnetic susceptibility due to the production of superparamagnetic and single domain magnetite amidst the warm and humid conditions at the time that defines the MMCO.
Most of these instances in Eurasia were limited to 40th parallel north. [2] Besides the findings from East Anglia, the first constant presence of humans in Europe begins 500,000–600,000 years ago. [3] However, this presence was limited to western Europe, not reaching places like the Russian plains, until 200,000–300,000 years ago. [3]
The Middle Miocene Climatic Transition (MMCT) was a relatively steady period of climatic cooling that occurred around the middle of the Miocene, roughly 14 million years ago (Ma), during the Langhian stage, [1] and resulted in the growth of ice sheet volumes globally, and the reestablishment of the ice of the East Antarctic Ice Sheet (EAIS).

During the Middle Miocene, the highly diversified mammalian fauna of the European forests were replaced by the faunas of the Late Miocene, adapted to a dry climate and to an open terrain. The beginning of the period is marked by the appearance and dispersal of the early horse Hipparion throughout Eurasia. The so-called Vallesian Crisis resulted ...
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 genus probably arose from Eurasian Miocene hyenas such as Thalassictis or Lycyaena, with C. borissiaki being the oldest known representative. [6] The species C. ossifragus was the only hyena to cross the Bering land bridge into the Americas , and ranged over what is now Arizona and Mexico during Blancan and early Irvingtonian Land Mammal ...
Ouranopithecus is a genus of extinct Eurasian great ape represented by two species, Ouranopithecus macedoniensis, a late Miocene (9.6–8.7 mya) hominoid from Greece [1] and Ouranopithecus turkae, also from the late Miocene (8.7–7.4 mya) of Turkey.
