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 ...
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 Messinian is in the geologic timescale the last age or uppermost stage of the Miocene. It spans the time between 7.246 ± 0.005 Ma and 5.333 ± 0.005 Ma (million years ago). It follows the Tortonian and is followed by the Zanclean, the first age of the Pliocene.
The Late Miocene (also known as Upper Miocene) is a sub-epoch of the Miocene Epoch made up of two stages. The Tortonian and Messinian stages comprise the Late Miocene sub-epoch, which lasted from 11.63 Ma ( million years ago ) to 5.333 Ma.
The Burdigalian is, in the geologic timescale, an age or stage in the early Miocene.It spans the time between 20.43 ± 0.05 Ma and 15.97 ± 0.05 Ma (million years ago). ). Preceded by the Aquitanian, the Burdigalian was the first and longest warming period of the Miocene [4] and is succeeded by the L
This is a list of official and unofficial names for time spans in the geologic timescale and units of chronostratigraphy.Since many of the smallest subdivisions of the geologic timescale were in the past defined on regional lithostratigraphic units, there are many alternative names that overlap.
The Miocene epoch, of the Neogene Period during the Cenozoic Era See also the preceding Category:Oligocene and the succeeding Category:Pliocene This category contains events which happened in the Miocene , a division of the geologic time scale .
It is of the early to middle Miocene epoch, (19.3 - 13.4 million years ago) in age, in the Neogene Period. [3] It lends its name to the Barstovian North American land mammal age . The sediments are fluvial and lacustrine in origin except for nine layers of rhyolitic tuff. [3]
