    en.wikipedia.org/wiki/Burdigalian

    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

    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 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.

    In northern Libya, a Late Miocene incised valley has been mapped with 150 kilometer length and at least 700 meter depth, far exceeding the Quaternary eustatic sea-level variations. [7] It turns out that during the Late Miocene, the Mediterranean Sea was blocked from the Atlantic at Gibraltar Strait and the Mediterranean became a deep but ...

    Quaternary geology is the branch of geology that study developments from 2.58 million years ago to the present. [ 1 ] [ 2 ] In particular, Quaternary geology study the process and deposits that developed during the Quaternary , a period characterized by glacial - interglacial cycles.

    en.wikipedia.org/wiki/Aquitanian_(stage)

    The Aquitanian Stage was named after the Aquitaine region in France and was introduced in scientific literature by Swiss stratigrapher Karl Mayer-Eymar in 1858.. The base of the Aquitanian (also the base of the Miocene Series and the Neogene System) is defined as the place in the stratigraphic column at the first appearance of foram species Paragloborotalia kugleri, the extinction of ...

    The onset of the India–Asia collision has been poorly constrained from Late Cretaceous to Oligo-Miocene due to different interpretations of geological evidences by different researchers.
