Target entity: Eocene–Oligocene extinction events
Context triple: [Eocene–Oligocene climate transition, associatedWith, Eocene–Oligocene extinction events]
  • A. Permian–Triassic mass extinction
    The Permian–Triassic mass extinction was the most severe biodiversity crisis in Earth's history, wiping out the majority of marine and terrestrial species around 252 million years ago and marking the boundary between the Paleozoic and Mesozoic eras.
  • B. Eocene–Oligocene climate transition
    The Eocene–Oligocene climate transition was a major global cooling event around 34 million years ago that marked the shift from a greenhouse to an icehouse Earth, including the formation of large Antarctic ice sheets.
  • C. Great Ordovician Biodiversification Event
    The Great Ordovician Biodiversification Event was a profound evolutionary radiation during the Ordovician Period that saw a dramatic increase in marine biodiversity and the establishment of many major animal groups in Paleozoic oceans.
  • D. Late Devonian extinction
    The Late Devonian extinction was a prolonged series of biodiversity crises around 375–359 million years ago that devastated marine life, especially reef ecosystems and armored fishes, and ranks among the largest mass extinctions in Earth’s history.
  • E. Carboniferous rainforest collapse
    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.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
