MN Zonation
The Mammal Neogene zones or MN zones are system of biostratigraphic zones in the stratigraphic record used to correlate mammal-bearing fossil localities of the Neogene period of Europe. It consists of seventeen consecutive zones (numbered MN 1 through MN 18; MN 7 and 8 have been joined into MN 7/8 zone) defined through reference faunas, well-known sites that other localities can be correlated with. MN 1 is the earliest zone, and MN 18 is the most recent. The MN zones are complementary with the MP zones in the Paleogene. The zones are as follows: See also * MP zonation * European land mammal age * Geologic time scale The geologic time scale, or geological time scale, (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochrono ...

Biostratigraphy
Biostratigraphy is the branch of stratigraphy which focuses on correlating and assigning relative ages of rock Stratum, strata by using the fossil assemblages contained within them.Hine, Robert. “Biostratigraphy.” ''Oxford Reference: Dictionary of Biology'', 8th ed., Oxford University Press, 2019. The primary objective of biostratigraphy is ''correlation'', demonstrating that a particular Horizon (geology), horizon in one geological section represents the same period of time as another horizon at a different section. Fossils within these strata are useful because sediments of the same age can look completely different, due to local variations in the Sedimentary depositional environment, sedimentary environment. For example, one section might have been made up of clays and marls, while another has more chalky limestones. However, if the fossil species recorded are similar, the two sediments are likely to have been laid down around the same time. Ideally these fossils are used to ...

Zanclean
The Zanclean is the lowest stage or earliest age on the geologic time scale of the Pliocene. It spans the time between 5.332 ± 0.005 Ma (million years ago) and 3.6 ± 0.005 Ma. It is preceded by the Messinian Age of the Miocene Epoch, and followed by the Piacenzian Age. The Zanclean can be correlated with regionally used stages, such as the Opoitian of New Zealand, and the Tabianian or Dacian of Central Europe. It also corresponds to the late Hemphillian to mid-Blancan North American Land Mammal Ages. In California, the Zanclean roughly corresponds to the middle part of the Delmontian stage. Definition The Zanclean Stage was introduced by Giuseppe Seguenza in 1868. It is named after ''Zancle'', the pre-Roman name for the Italian city of Messina on Sicily. The base of the Zanclean (and the Pliocene Series) lies with the top of magnetic chronozone Cr3 (about 100,000 years before the Thvera normal subchronozone C3n.4n). The base is also close to the extinction level of the calc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Serravallian
The Serravallian is, in the geologic timescale, an List of time periods, age or a stage (stratigraphy), stage in the middle Miocene epoch (geology), Epoch/series (stratigraphy), Series, which spans the time between 13.82 annum, Ma and 11.63 Ma (million years ago). The Serravallian follows the Langhian and is followed by the Tortonian. It overlaps with the middle of the Astaracian European Land Mammal Mega Zone, the upper Barstovian and lower Clarendonian North American Land Mammal Ages and the Laventan and lower Mayoan South American Land Mammal Ages. It is also coeval with the Sarmatian and upper Badenian Stages of the Paratethys time scale of Central and eastern Europe. Definition The Serravallian Stage was introduced in stratigraphy by the Italy, Italian geologist Lorenzo Pareto in 1865. It was named after the town of Serravalle Scrivia in northern Italy.

MN 9 (biostratigraphic Zone)
State Highway 9 or Trunk Highway 9 (MN 9, TH 9) is a state highway in west-central and northwest Minnesota, which runs from its intersection with MN 23 in New London and continues west and then north to its northern terminus at its intersection with US Highway 2 (US 2) in Fairfax Township near Crookston.

Messinian
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).
