The Carboniferous rainforest collapse (CRC) was a minor extinction event that occurred around 305 million years ago in the Carboniferous period. [1] The event occurred at the end of the Moscovian and continued into the early Kasimovian stages of the Pennsylvanian (Upper Carboniferous).
The Carboniferous (/ ˌ k ɑːr b ə ˈ n ɪ f ər ə s / KAR-bə-NIF-ər-əs) [6] is a geologic period and system of the Paleozoic era that spans 60 million years, from the end of the Devonian Period 358.86 Ma (million years ago) to the beginning of the Permian Period, 298.9 Ma.
The Carboniferous rainforest collapse was caused by a cooler drier climate that initially fragmented, then collapsed the rainforest ecosystem. [2] During most of the rest of Carboniferous times, the coal forests were mainly restricted to refugia in North America (such as the Appalachian and Illinois coal basins) and central Europe.
It is the third stage in the Pennsylvanian (late Carboniferous), lasting from 307 to 303.7 Ma. [3] The Kasimovian Stage follows the Moscovian and is followed by the Gzhelian . The Kasimovian saw an extinction event which occurred around 305 mya, referred to as the Carboniferous Rainforest Collapse . [ 4 ]

The Mississippian (/ ˌ m ɪ s ɪ ˈ s ɪ p i. ə n / MISS-iss-IP-ee-ən), [5] also known as Lower Carboniferous or Early Carboniferous, is a subperiod in the geologic timescale or a subsystem of the geologic record. It is the earlier of two subperiods of the Carboniferous period lasting from roughly 358.9 to 323.2
In the middle or late Carboniferous, smaller forms gave rise to the first reptiles. [29] In the late Carboniferous, a global rainforest collapse favoured the more terrestrially adapted reptiles, while the many of their amphibian relatives failed to reestablish. [42] Some reptile-like amphibians did flourish in the new seasonal environment.
