Target entity: Permian–Triassic mass extinction
Context triple: [Triassic, beginsAfter, Permian–Triassic mass extinction]
  • A. Permian–Triassic mass extinction chosen
    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. 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.
  • C. Cretaceous–Paleogene boundary
    The Cretaceous–Paleogene boundary marks the geological transition 66 million years ago associated with a mass extinction event that wiped out non-avian dinosaurs and many other species, likely triggered by a large asteroid impact.
  • D. Cambrian explosion
    The Cambrian explosion was a relatively brief period around 541 million years ago when most major animal groups rapidly appeared in the fossil record, dramatically increasing the complexity and diversity of life on Earth.
  • E. Permian Period
    The Permian Period was the final period of the Paleozoic Era, marked by the diversification of reptiles and the largest mass extinction in Earth's history at its close.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
