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 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 Neogene (/ ˈ n iː. ə dʒ iː n / NEE-ə-jeen, [6] [7]) is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period 23.03 million years ago to the beginning of the present Quaternary Period 2.58 million years ago.
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. [5] Figure illustrating the definition of continental collision onset in planar view. Modified after Hu et al. (2016).
In Early Miocene times (24–21 Ma), a series of thrust sheets was emplaced over Northland, [2] extending as far south as the Kaipara Harbour and Albany areas. The rocks came from the northeast (perhaps beyond the Vening Meinesz Fracture Zone), and were emplaced in reverse order, but the right way up.
The late Piacenzian may be when the genus Homo developed out of the ancestral genus Australopithecus. [13] While the oldest known fossils unambiguously identified as Homo habilis date to just after the end of the Piacenzian (2.58 Ma), a fossilized jawbone that exhibits traits that are transitional between Australopithecus and Homo habilis was ...
The Cerro Azul Formation (Spanish: Formación Cerro Azul), also described as Epecuén Formation, is a geological formation of Late Miocene (Tortonian, or Huayquerian in the SALMA classification) age in the Colorado Basin of the Buenos Aires and La Pampa Provinces in northeastern Argentina.
