Middle Devonian

The Middle Devonian epoch was a time long ago, from about 393 million to 382 million years ago, during the larger Devonian period. It came after the Emsian age and was an important part of Earth's history. This epoch helps scientists understand how our planet and its life have changed over millions of years.

The Middle Devonian is split into two main stages called the Eifelian and the Givetian. These stages help experts study and organize the rocks and fossils from this time. By looking at these layers, we can learn about the ancient oceans, climates, and the many new kinds of plants and animals that were appearing on Earth.

Life in the Middle Devonian

During the Middle Devonian, jawless fish called ostracoderms were becoming less common, while jawed fish were becoming more diverse and thriving in both oceans and freshwater. These shallow, warm waters helped early fish develop important traits, such as lungs and the ability to move out of water for short periods.

The earliest forest appeared in the Middle Devonian, during the Eifelian time. These forests were made up of cladoxylopsid trees, including Calamophyton.
