The Cenozoic Era: Definition, Time Period & Facts Cenozoic Era. The Cenozoic Era began 65 million years ago with an asteroid impact that killed off a majority of the dinosaurs and ends at the present day. The Cenozoic is commonly divided into three periods: Paleogene (65.5 to 23.03 million years ago) Neogene (23.03 to 2.6 million years ago) Quaternary (2.6 million years ago to present) KT Extinction

The Cenozoic Era: Age of Mammals This was beneficial to insects, many of which evolved symbiotic relationships with flowering plants. The Cenozoic includes the period that began roughly 65 million years ago to the present. Historically, the Era has been divided into two periods: the Tertiary and the Quaternary.

Mesozoic Era: Age of the Dinosaurs The Mesozoic Era began roughly around the time of the end-Permian extinction, which wiped out 96 percent of marine life and 70 percent of all terrestrial species on the planet. Life slowly rebounded, eventually giving way to a flourishing diversity of animals, from massive lizards to monstrous dinosaurs.

- From EvoWiki. The K/T boundary event marks a monumental change in environmental conditions and in life forms. The event marks the transition from the Mesozoic Era with its final Cretaceous (K) period and the Cenozoic Era and its initial period, the Tertiary, in the Geological Timescale. The boundary occurred 65 million (6.5x10 7) years ago.

Cenozoic Era The Cenozoic Era was the first era that saw humans evolve. Much of what the common population thinks of as evolution all happened in the Cenozoic Era. The first period of the Cenozoic Era is called the Tertiary Period.Recently, the Tertiary Period has been broken down into the Paleogene Period and Neogene Period.he modern human evolved and became the dominant species on Earth. Other mammals on Earth continued to diversify and branch off into various species. The same happened with marine species. There were a few extinctions over this time period as well, due to the changing climate.

Phanerozoic Phanerozoic (fān'ər-ə-zō'ĭk) The period of geologic time from about 540 million years ago to the present, including the Paleozoic, Mesozoic, and Cenozoic Eras. When this period of time was first defined, it was thought to coincide with the first appearance of life in the fossil record. It is now known that bacterial and other forms of life were present in the Precambrian Eon, and the Phanerozoic is understood to coincide with the appearance of life forms that evolved external skeletons.

Mesozoic Era Paleobiology Mesozoic Era (245 to 65 mya). One of the most striking events in the Mesozoic Era was the rise to dominance of dinosaurs in terrestrial ecosystems. The Mesozoic lasted from 245 to 65 million years ago, and is divided into three periods. The Mesozoic, which derives its name from the Greek with a rough meaning of middle animals, began after the Permian extinction and ended with the Cretaceous extinction.

Evolution of tetrapods The Cenozoic is sometimes called the Age of Mammals, because the largest land animals have been mammals during that time. This is a misnomer for several reasons. First, the history of mammals began long before the Cenozoic began. Second, the diversity of life during the Cenozoic is far wider than mammals.

Cenozoic Fossils Cenozoic Time Period The Cenozoic time period started after the extinction of non-avian dinosaurs to today. Also, another name for the Cenozoic Era is Age of Mammals. The Cenozoic Era is the third era in history and most recent era. The Cenozoic era is divided into periods: the Paleogene, Neogene, and Quaternary period. The word Cenozoic is the Greek word for new or recent. Each period in the Cenozoic Era is divided into epochs. The Paleogene period three epochs are called Palocene, Eocene, and Pliocene. The Neogene period two epochs are called Miocene and Pliocene. The Quaternary period two epochs are called Holocene and Pleistocene.

Which Era Is Known As the Age of Reptiles? The Mesozoic Era is divided into three different periods: the Triassic, the Jurassic, and the Cretaceous. It spanned from approximately 245 million years ago to 65 million years ago.The Mesozoic Era was followed by the Cenozoic Era, which is the current era. The Mesozoic Era ended with the extinction of the dinosaurs.

Cenozoic Fossils Cave lions, Sabre-toothed cats, cave bears, giant deer, woolly rhinoceroses, and woolly mammoths were prevailing species of the Quaternary Period. Without the dinosaurs, plant life had an opportunity to flourish during the Cenozoic Era. Nearly every plant living today had its roots in the Cenozoic Era. During the early part of the era, forests overran most of North America. However, as the climate cooled forests died off, creating open land. Due to the widening of the oceans,sharks, whales and other marine life proliferated.

- View full size image. The Cretaceous Period was the last and longest segment of the Mesozoic Era. It lasted approximately 79 million years, from the minor extinction event that closed the Jurassic Period about 145.5 million years ago to the Cretaceous-Paleogene (K-Pg) extinction event dated at 65.5 million years ago. In the early Cretaceous, the continents were in very different positions than they are today.
