Cenozoic era periods

The Cenozoic Era, which began 66 million years ago, is the most recent geological period on Earth. During this era, the continents shifted into their current positions, major mountain ranges were formed, and a variety of plants and animals emerged. Early primates and mammals diversified during the Paleogene, the earliest part of the Cenozoic..

2. Holocene (12,000-2,000 years ago) The Holocene is one of the most recent epochs, dating back 12,000 years ago and finishing just 2,000 years back. The rising temperatures during this period again led to the extinction of animals that had adapted to the cold climate of the Pleistocene.The Cenozoic era, for example, is known as the "Age of Mammals." The Carboniferous period, on the other hand, is named for the large coal beds that were formed during this time ("carboniferous" means coal-bearing). The Cryogenian period, as its name suggests, was a time of great glaciations.Cenozoic Era . In the Palaeogene Period, Britain had a very warm climate, but it gradually cooled as Britain drifted northwards. By the Quaternary, glaciers covered the middle and north of Britain, shaping the landscape we see today. The first humans occupied Britain during the Quaternary.

Most of the boundaries between the periods and epochs of the geological time scale have been fixed on the basis of significant changes in the fossil record.It lasted all through the time of the non-avian dinosaurs during the Mesozoic Era, and ended 33.9 million years ago in the middle of the Cenozoic Era (the current Era). This greenhouse period lasted 226.1 million years. The hottest part of the last greenhouse earth was the Late Paleocene - Early Eocene. This was a hothouse period that lasted ... The Eocene epoch is part of the Tertiary Period in the Cenozoic Era, and lasted from about 54.8 to 33.7 million years ago (mya). The oldest known fossils of most of the modern orders of mammals appear in a brief period during the Early Eocene and all were small, under 10 kg.

Large limestone outcrops, like the one pictured here, are evidence of these periodic incursions of continental seas. The Paleozoic Era is bracketed by the times of global super-continents. The era opened with the breakup of the world-continent Pannotia and closed with the formation of Pangea, as the Earth's continents came together once again. The Cenozoic Era spans the interval from 66 million years ago to present. It is divided into the Paleogene Period (66–23 million years ago) and Neogene Period (23 million years …Cenozoic climates.

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 geochronology (a scientific branch of geology that aims to determine the age of rocks).The Cenozoic era (consisting of the Paleogene and Neogene periods, 66 million years ago to present) was an age of diversification and evolution of mammals, ...The term Late Cenozoic Ice Age is used to include this early phase. The previous ice age, the Saale glaciation, which ended about 128,000 years ago, was more severe than the Last Glacial Period in some areas such as Britain, but less severe in others. During this last glacial period, alternating episodes of glacier advance, and retreat occurred. ….
