Neogene

The Neogene is a geologic period that spans from about 23 million to 2.58 million years ago. It is the second period of the Cenozoic Era and is divided into two epochs: the Miocene and the Pliocene. The Neogene is known for significant geological and biological changes, including the diversification of mammals, the development of grasslands, and the formation of the Isthmus of Panama.

Key Concepts to Understand:

• Geological time scale
• Epochs within the Neogene period
• Major geological and biological events during the Neogene
• Impact of the Neogene on the Earth's climate and ecosystems

Study Tips:

When studying the Neogene, it's important to familiarize yourself with the key epochs and events that occurred during this period. Use visual aids such as timelines and diagrams to help you understand the sequence of geological and biological changes. Additionally, make connections between the Neogene and its impact on the Earth's climate and ecosystems to gain a deeper understanding of the period's significance.
