Target entity: Permian–Triassic extinction event
Context triple: [Therapsids, survivedEvent, Permian–Triassic extinction event]
  • 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. Triassic–Jurassic extinction event
    The Triassic–Jurassic extinction event was a major mass extinction around 201 million years ago that wiped out many marine and terrestrial species, paving the way for dinosaurs to become the dominant land animals in the Jurassic Period.
  • C. 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.
  • D. 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.
  • E. Lomagundi event
    The Lomagundi event was a prolonged Paleoproterozoic episode of unusually high carbon isotope ratios in marine carbonates, interpreted as evidence for a major global increase in oxygen production and organic carbon burial.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
