Phrase: Late Ordovician mass extinction | Statement: [Ordovician Period, endedWith, Late Ordovician mass extinction]
NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07
Target entity: Late Ordovician mass extinction
Context triple: [Ordovician Period, endedWith, Late Ordovician mass extinction]
  • A. 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.
  • B. 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.
  • C. 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.
  • D. Capitanian (Guadalupian) mass extinction
    The Capitanian (Guadalupian) mass extinction was a major mid-Permian biodiversity crisis that significantly reduced marine life and set the stage for the even larger end-Permian extinction.
  • E. 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.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
