Target entity: Carboniferous rainforest collapse Context triple: [Equatorial Euramerica, hasEvent, Carboniferous rainforest collapse]
-
A.
Carboniferous rainforest collapse
chosen
The Carboniferous rainforest collapse was a mass extinction and fragmentation event of vast tropical coal-forest ecosystems around 305 million years ago, profoundly reshaping terrestrial biodiversity and climate in the late Paleozoic.
-
B.
Phanerozoic mass extinctions
Phanerozoic mass extinctions are the handful of catastrophic, globally disruptive biodiversity crises over the last ~540 million years that abruptly wiped out large proportions of Earth’s species and reshaped the course of evolution.
-
C.
Devonian fossil forests
Devonian fossil forests are some of the oldest known forest ecosystems on Earth, preserving early tree-like plants that reveal how terrestrial forests first evolved and transformed the planet’s environment.
-
D.
Paleozoic mass extinctions
Paleozoic mass extinctions were several major biodiversity crises between roughly 541 and 252 million years ago that dramatically reshaped marine and terrestrial life, including events like the Kellwasser extinctions and culminating in the end-Permian “Great Dying.”
-
E.
Late Ordovician mass extinction
The Late Ordovician mass extinction was one of Earth’s largest biodiversity crises, during which severe climate change and glaciation led to the rapid loss of a substantial portion of marine species.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
