The Carboniferous period, spanning from approximately 358 to 298 million years ago, was a time of significant geological and biological developments.
It is renowned for its lush forests and vast swampy landscapes that eventually gave rise to much of the coal reserves we use today.
The period also marked a key transition in Earth’s history, as plants began to diversify and vertebrate life began its evolutionary journey towards modern forms.
The Carboniferous is known for the emergence of early amphibians, which were among the first vertebrates to venture onto land.
These developments laid the groundwork for the eventual rise of reptiles and the dominance of dinosaurs in later periods.
