The Late Cenozoic Ice Age falls within the Cenozoic Era which started 66 million years ago. The Cenozoic Era is part of the Phanerozoic Eon which started ~538.8 million years ago. ^ abIn standard nomenclature the Pleistocene Epoch lasts from 2.58 Ma to 11.7 ka and the Holocene epoch lasts from 11.7 ka to present.
The Cenozoic is also known as the Age of Mammals because the terrestrial animals that dominated both hemispheres were mammals – the eutherians (placentals) in the northern hemisphere and the metatherians (marsupials, now mainly restricted to Australia and to some extent South America) in the southern hemisphere. The extinction of many groups ...
Late Cenozoic Ice Age, the geologic period of the last 33.9 million years. Little Ice Age, a period of relative cold in certain regions from roughly 1450–1480. Pleistocene, a geologic epoch, often colloquially referred to as the "Ice Age", that includes the world's most recent repeated glaciations (2,580,000 to 11,700 years ago) Plio ...
A chronology of climatic events of importance for the Last Glacial Period, about the last 120,000 years The Last Glacial Period caused a much lower global sea level.. The Last Glacial Period (LGP), also known as the Last glacial cycle, occurred from the end of the Last Interglacial to the beginning of the Holocene, c. 115,000 – c. 11,700 years ago, and thus corresponds to most of the ...
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 Quaternary (/ kwəˈtɜːrnəri, ˈkwɒtərnɛri / kwə-TUR-nə-ree, KWOT-ər-nerr-ee) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). [4] It follows the Neogene Period and spans from 2.58 million years ago to the present. [5]
Cooler climate causes Carboniferous rainforest collapse. 251.9. Permian–Triassic extinction event. 199.6. Triassic–Jurassic extinction event, causes as yet unclear. 66. Perhaps 30,000 years of volcanic activity form the Deccan Traps in India, or a large meteor impact. 66. Cretaceous–Paleogene boundary and Cretaceous–Paleogene extinction ...
An illustration of ice age Earth at its glacial maximum. A "greenhouse Earth" is a period during which no continental glaciers exist anywhere on the planet. [6] Additionally, the levels of carbon dioxide and other greenhouse gases (such as water vapor and methane) are high, and sea surface temperatures (SSTs) range from 28 °C (82.4 °F) in the tropics to 0 °C (32 °F) in the polar regions.
