The Paleocene (IPA: / ˈpæli.əsiːn, - i.oʊ -, ˈpeɪli -/ PAL-ee-ə-seen, -ee-oh-, PAY-lee-), [ 4 ] or Palaeocene, is a geological epoch that lasted from about 66 to 56 million years ago (mya). It is the first epoch of the Paleogene Period in the modern Cenozoic Era. The name is a combination of the Ancient Greek παλαιόςpalaiós ...
The Paleocene is the first series/epoch of the Paleogene and lasted from 66.0 Ma to 56.0 Ma. It is divided into three stages: the Danian 66.0 - 61.6 Ma; Selandian 61.6 - 59.2 Ma; and, Thanetian 59.2 - 56.0 Ma. [13] The GSSP for the base of the Cenozoic, Paleogene and Paleocene is at Oued Djerfane, west of El Kef, Tunisia.
It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name Eocene comes from the Ancient Greek Ἠώς (Ēṓs, " Dawn ") and καινός (kainós, "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. [ 7 ][ 8 ] The Eocene spans the time from the end of the Paleocene Epoch to the ...
The Cretaceous–Paleogene (K–Pg) extinction event, [ a ] also known as the K–T extinction, [ b ] was the mass extinction of three-quarters of the plant and animal species on Earth [ 2 ][ 3 ] approximately 66 million years ago. The event caused the extinction of all non-avian dinosaurs. Most other tetrapods weighing more than 25 kilograms ...
The Pliocene (/ ˈplaɪ.əsiːn, ˈplaɪ.oʊ -/ PLY-ə-seen, PLY-oh-; [ 6 ][ 7 ] also Pleiocene) [ 8 ] is the epoch in the geologic time scale that extends from 5.33 to 2.58 [ 9 ] million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by ...
The Paleocene–Eocene thermal maximum (PETM), alternatively ” Eocene thermal maximum 1 (ETM1) “ and formerly known as the " Initial Eocene " or “ Late Paleocene thermal maximum ", was a geologically brief time interval characterized by a 5–8 °C global average temperature rise and massive input of carbon into the ocean and atmosphere ...
The Carboniferous (/ ˌkɑːrbəˈnɪfərəs / KAR-bə-NIF-ər-əs) [ 6 ] is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period 358.9 Ma (million years ago) to the beginning of the Permian Period, 298.9 Ma.
The Quaternary spans from 2.58 million years ago to present day, and is the shortest geological period in the Phanerozoic Eon. It features modern animals, and dramatic changes in the climate. It is divided into two epochs: the Pleistocene and the Holocene. The Pleistocene lasted from 2.58 million to 11,700 years ago.
