Target entity: Late Ordovician mass extinction
Context triple: [Late Ordovician, hasMajorEvent, Late Ordovician mass extinction]
  • A. Late Ordovician mass extinction chosen
    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.
  • B. 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.”
  • C. 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.
  • 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. 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.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
