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). It altered the vast coal forests that covered the ...
Carboniferous. The Carboniferous (/ ˌkɑːrbəˈnɪfərəs / KAR-bə-NIF-ər-əs) [6] is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period 358.9 Ma (million years ago) to the beginning of the Permian Period, 298.9 Ma. In North America, the Carboniferous is often treated as two ...
Plotted is the extinction intensity, calculated from marine genera. The Late Devonian extinction consisted of several extinction events in the Late Devonian Epoch, which collectively represent one of the five largest mass extinction events in the history of life on Earth. The term primarily refers to a major extinction, the Kellwasser event ...
Meganeura is a genus of extinct insects from the Late Carboniferous (approximately 300 million years ago). They resembled and are related to the present-day dragonflies and damselflies, and were predatory, with their diet mainly consisting of other insects.
Ecosystem collapse has been defined as a "transformation of identity, loss of defining features, and replacement by a novel ecosystem", and involves the loss of "defining biotic or abiotic features", including the ability to sustain the species which used to be associated with that ecosystem. [1] According to another definition, it is "a change ...
A cataclysm engulfed the planet some 252 million years ago, wiping out more than 90% of all life. Known as the Great Dying, the mass extinction that ended the Permian geological period was the ...
Stages 4 and 5 (0.85 Ga – present): Other O 2 reservoirs filled; gas accumulates in atmosphere. [ 1 ] The Great Oxidation Event (GOE) or Great Oxygenation Event, also called the Oxygen Catastrophe, Oxygen Revolution, Oxygen Crisis or Oxygen Holocaust, [ 2 ] was a time interval during the Earth 's Paleoproterozoic era when the Earth's ...
The Cretaceous–Paleogene (K–Pg) extinction event, [ a ] also known as the Cretaceous–Tertiary(K–T)extinction, [ b ] was the mass extinction of three-quarters of the plant and animal species on Earth [ 2 ][ 3 ] approximately 66 million years ago. The event caused the extinction of all non-avian dinosaurs.
