The Cenozoic Era is generally divided into three periods: the Paleogene (66 million to 23 million years ago), the Neogene (23 million to 2.6 million years ago), and the Quaternary (2.6 million years ago to the present); however, the era has been traditionally divided into the Tertiary and Quaternary periods.

What is Tertiary period of Cenozoic Era?

Tertiary Period, former official interval of geologic time lasting from approximately 66 million to 2.6 million years ago. It is the traditional name for the first of two periods in the Cenozoic Era (66 million years ago to the present); the second is the Quaternary Period (2.6 million years ago to the present).

The Quaternary Period is a geologic time period that encompasses the most recent 2.6 million years — including the present day.

What happened during the Quaternary period?

The Quaternary Period is famous for the many cycles of glacial growth and retreat, the extinction of many species of large mammals and birds, and the spread of humans. The Quaternary Period is divided into two epochs, from youngest to oldest: the Holocene and Pleistocene.

What caused the Cretaceous period?

As originally proposed in 1980 by a team of scientists led by Luis Alvarez and his son Walter, it is now generally thought that the K–Pg extinction was caused by the impact of a massive comet or asteroid 10 to 15 km (6 to 9 mi) wide, 66 million years ago, which devastated the global environment, mainly through a …

What was the Cretaceous era?

Mesozoic
Cretaceous/Era
Cretaceous Period, in geologic time, the last of the three periods of the Mesozoic Era. The Cretaceous began 145.0 million years ago and ended 66 million years ago; it followed the Jurassic Period and was succeeded by the Paleogene Period (the first of the two periods into which the Tertiary Period was divided).

What defines the Quaternary period?

The Quaternary Period is typically defined by the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused.

What animals live in the Tertiary period?

Fish species branched out during the Tertiary Period. Sharks became more plentiful. Trout and bass evolved. The insect population increased in the Tertiary Period. Bees and other insects that lived on pollen and nectar of the flowering plants prospered.

What happened during the Cenozoic era?

The Cenozoic era was one of the most important periods as it marked the point at which dinosaurs disappeared and mammals appeared, the continents acquired the configuration and location they have today, and the flora and fauna evolved. What happened during the Cenozoic era.

How old is the Cenozoic era?

The Cenozoic Era, which began about 65 million years ago and continues into the present, is the third documented era in the history of Earth. The current locations of the continents and their modern-day inhabitants, including humans, can be traced to this period.

When did the Cenozoic era end?

The Cenozoic era was the third major epoch of earth’s history, beginning approximately 66 million years ago and extending to the present.
