What is the cenozoic era.

Cenozoic Era: Stratigraphy. The Cenozoic is divided into two main sub-divisions: the Tertiary and the Quaternary. Most of the Cenozoic is the Tertiary, from 65 million years ago to 1.8 million years ago. The Quaternary includes only the last 1.8 million years. The concepts of Tertiary and Quaternary have an interesting history. The Cenozoic Era (66 million years ago through today) is the "Age of Mammals." Birds and mammals rose in prominence after the extinction of giant reptiles. Common Cenozoic fossils include cat-like carnivores and early horses, as well as ice age fossils like wooly mammoths. Caves can preserve the remains of ice-age animals that died in them or ...8.8: Cenozoic. Figure 8.8. 1: Paraceratherium, seen in this reconstruction, was a massive (15-20 ton, 15 foot tall) ancestor of rhinos. The Cenozoic, meaning “new life,” is known as the age of mammals because it is in this era that mammals came to be a dominant and large life form, including human ancestors.Online exhibits: Geologic time scale: Cenozoic Era. The Holocene Epoch. To observe a Holocene environment, simply look around you! The Holocene is the name given to the last 11,700 years* of the Earth's history — the time since the end of the last major glacial epoch, or "ice age." It is the beginning of the Cenozoic Era of the present Phanerozoic Eon. The earlier term Tertiary Period was used to define the span of time now covered by the Paleogene Period and subsequent Neogene Period; despite no longer being recognized as a formal stratigraphic term, "Tertiary" still sometimes remains in informal use.

The Cenozoic Era (IPA pronunciation: Template:IPA); sometimes Caenozoic Era in the United Kingdom) meaning "new life" (Greek kainos = new + zoe = life) is the most recent of the three classic geological eras.

Darren OrfThe Cenozoic era (last ~66 Ma) exhibited changing CO 2, climate, and sea levels, providing tests of interrelationships, especially during the last 50 Ma, when long-term global climate shifted from hothouse/greenhouse conditions, typified by high atmospheric CO 2 and ice-free conditions, to fully glaciated icehouse conditions with low CO 2 .T he Cenozoic is the youngest and most recent of Earth's geologic eras. Emerging from a time of mass extinction, Cenozoic animals diversified, filling the empty niches previously occupied by the dinosaurs. The era was characterized by the radiation of mammals, the proliferation of grasses across the planet, and the migration of continents to their present location.The Cenozoic (meaning "new life") era is the most recent of the three classic geological eras of the geologic time scale. It covers the 65.5 million years since the Cretaceous-Tertiary extinction event at the end of the Cretaceous and is ongoing in the present time.An ice age is a period of colder global temperatures and recurring glacial expansion capable of lasting hundreds of millions of years. Thanks to the efforts of geologist Louis Agassiz and ...Descriptions of animal life throughout the era. During the Cenozoic Era, fauna in general underwent dramatic changes. Species like dinosaurs, large swimming reptiles, microscopic plankton had extinguished by this time. Many present-day mammals, like placental, marsupials, and ungulates originated during this era.

The Neogene Period is the middle period of the three periods of the Cenozoic Era. Like the other periods of the Cenozoic, it is geologically short (less than 1% of geologic time) but well-represented at the surface. Neogene sedimentary formations are often poorly lithified, because they are young and generally have not been deeply buried.The Cenozoic era is the era that is by far the best studied and known by the scientists. The main reason for this is that this era is the most recent one, and it is actually the era we live in.
