Carboniferous rainforest collapse
The Carboniferous Rainforest Collapse (CRC) was a minor extinction event that occurred around 305 million years ago in the Carboniferous period. It altered the vast coal forests that covered the equatorial region of Euramerica (Europe and America). This event may have fragmented the forests into isolated 'islands', which in turn caused dwarfism and shortly after, then extinction of many plant and animal species. Following the event, coal-forming tropical forests then continued in large-areas of the earth, but their extent and composition were changed.
The event occurred at the end of the Moscovian and continued into the early Kasimovian stages of the Pennsylvanian. The CRC can also be viewed as part of a broader transition of plant species called the "Carboniferous-Permian transition" that continued for another 10 million years into the early Permian. This larger transition has been recognized as one of the two largest extinction events for plant life.
==Extinction patterns on land==
In the Carboniferous, the great tropical rainforests of Euramerica supported towering lycopodiophyta, a heterogeneous mix of vegetation, as well as a great diversity of animal life: giant dragonflies, millipedes, cockroaches, amphibians, and the first amniotes.
