The Cenozoic era is also known as the Age of Mammals because the extinction of many groups of giant mammals , allowing smaller species to thrive and diversify because their predators no longer existed. ... The beginning of the Paleogene period was a time for the mammals that survived from the Cretaceous period.
What does Cenozoic mean and what is this era known for?
Cenozoic (66 million years ago until today) means ‘recent life . ‘ During this era, plants and animals look most like those on Earth today. Periods of the Cenozoic Era are split into even smaller parts known as Epochs, so you will see even more signposts in this Era.
What major events happened in the Cenozoic Era?

What are some interesting facts about the Cenozoic Era?
During the Oligodene epoch mammals began to evolve to include marsupials, dogs, and elephants. Plants were thriving and evolving and evergreen trees began to grow in this period as well. The Neogene Period is the shortest period of the Cenozoic Era. It is divided into only two epochs – the Miocene and Pliocene epochs.
What is the Cenozoic era defined by?
Cenozoic Era, third of the major eras of Earth’s history, beginning about 66 million years ago and extending to the present. It was the interval of time during which the continents assumed their modern configuration and geographic positions and during which Earth’s flora and fauna evolved toward those of the present .
What is the era we live in today?
Our current era is the Cenozoic , which is itself broken down into three periods. We live in the most recent period, the Quaternary, which is then broken down into two epochs: the current Holocene, and the previous Pleistocene, which ended 11,700 years ago.
What is the longest era?
The longest timeframe officially designated as an era is the Paleoproterozoic , which lasted 900 million years from 2,500-1,600 mya.
Why isn’t there an end for the Cenozoic Era?
There were a few extinctions over this period due to the changing climate but plants adapted to the various climates that emerged after the glaciers retreated. Tropical areas never had glaciers, so lush, warm-weather plants thrived all during the Quaternary Period.

How old is the shortest era?
Quaternary Period
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.
What are three major events that happened in the Cenozoic Era?
The Cenozoic Era is divided into two periods, the Paleogene and Neogene which are divided into epochs. The Cenozoic has seen the extinction of the non-avian dinosaurs and the rise of mankind . It is marked by the Cretaceous-Tertiary extinction event at the end of the Cretaceous period and the end of the Mesozoic Era.
Why did the Cenozoic era began?
It started with the Cretaceous–Paleogene extinction event , when many species, including the non-avian dinosaurs, became extinct in an event attributed by most experts to the impact of a large asteroid or other celestial body, the Chicxulub impactor.

Which period is called Age of Reptiles?
During the Mesozoic , or “Middle Life” era, life diversified rapidly and giant reptiles, dinosaurs and other monstrous beasts roamed the Earth. The period, which spans from about 252 million years ago to about 66 million years ago, was also known as the age of reptiles or the age of dinosaurs.
