Period 1 Carboniferous
Carboniferous Period - 359-299 million years ago
Overview of environment - a warm climate with low sea levels and a high amount of oxygen in the atmosphere leading to the development of extremely large plants and insects. The earth's climate shifted constantly between glacial and interglacial climates, similar to today.
Significant events - the continents collided to form Pangea, leading to many orogenies (the crust folding to form mountains), at the end of this period the Carboniferous rainforest collapsed due to climate change.
