Carboniferous rainforest collapse is sometimes treated as an extinction factor for large Carboniferous arthropods such as giant griffinfly Meganeura and millipede Arthropleura. It is common theory that high oxygen levels have led to larger arthropods, and these organisms have been thought to live in forests.
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 ]
Cooler climate causes Carboniferous rainforest collapse: 251.9: Permian–Triassic extinction event: 199.6: Triassic–Jurassic extinction event, causes as yet unclear 66: Perhaps 30,000 years of volcanic activity form the Deccan Traps in India, or a large meteor impact. 66

This timeline of Carboniferous research is a chronological listing of events in the history of geology and paleontology focused on the study of earth during the span of time lasting from 358.9 to 298.9 million years ago and the legacies of this period in the rock and fossil records.
Throughout the Carboniferous, there was a cooling pattern, which eventually led to the glaciation of Gondwana as much of it was situated around the South Pole. This event was known as the Permo-Carboniferous Glaciation and resulted in a major loss of coal forests, known as the Carboniferous rainforest collapse. [18]
