Input
Phrase: Cretaceous–Paleogene extinction event | Statement: [Theropoda, majorExtinctionEvent, Cretaceous–Paleogene extinction event]
NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07
Target entity: Cretaceous–Paleogene extinction event
Context triple: [Theropoda, majorExtinctionEvent, Cretaceous–Paleogene extinction event]
  • A. Cretaceous–Paleogene boundary chosen
    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.
  • B. 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.
  • C. 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.
  • 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. 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.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.

Target predicate: majorExtinctionEvent
Context triple: [Theropoda, majorExtinctionEvent, Cretaceous–Paleogene extinction event]
  • A. extinctionEvent chosen
    Indicates a large-scale occurrence that causes the widespread or complete disappearance of one or more species or higher taxonomic groups.
  • B. massExtinctionCount
    Indicates the number of mass extinction events associated with or affecting a given entity or context.
  • C. majorTectonicEvent
    Indicates a significant geological event involving large-scale movement or deformation of the Earth's tectonic plates, such as major earthquakes, volcanic eruptions, or continental shifts.
  • D. extinctionPeriod
    Indicates the time span during which an entity ceases to exist or is considered extinct.
  • E. extinct
    Indicates that the referenced entity no longer exists as a living or active member of its former kind or category.
  • F. None of above.
