The Caenozoic Era: An Overview
Caenozoic is the youngest geological era that spans from about 66 million years ago to the present day. It is also known as the Cenozoic Era, which means "new life." This era is characterized by the diversification of mammals, birds, insects, and plants, as well as the rise of modern ecosystems.
Geological Events
The Caenozoic Era is divided into three periods: the Paleogene, Neogene, and Quaternary. During this time, notable geological events took place, such as the formation of the Himalayas, the opening of the Atlantic Ocean, and the uplifting of the Rocky Mountains.
Climate Changes
Throughout the Caenozoic Era, Earth's climate experienced significant fluctuations. The Paleogene period was generally warm, with high levels of carbon dioxide in the atmosphere. However, towards the end of the era, the planet underwent cooling, leading to ice ages during the Quaternary period.
Flora and Fauna
The Caenozoic Era saw the evolution and diversification of many plant and animal species. Mammals, in particular, thrived during this time, with the emergence of modern groups like primates, whales, and rodents. The era also witnessed the spread of grasslands and the adaptation of plants to new environments.
Impact of Humans
In the more recent Quaternary period, humans emerged and began to have a significant impact on the planet. The Caenozoic Era marked the spread of modern humans around the globe, leading to changes in ecosystems, landscapes, and climates through activities such as agriculture, urbanization, and industrialization.
