Input
Phrase: Cretaceous–Paleogene boundary | Statement: [Raton Formation, spansBoundary, Cretaceous–Paleogene boundary]
NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07
Target entity: Cretaceous–Paleogene boundary
Context triple: [Raton Formation, spansBoundary, Cretaceous–Paleogene boundary]
  • 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. Frasnian–Famennian boundary
    The Frasnian–Famennian boundary marks a major Late Devonian mass extinction interval characterized by severe global environmental upheavals and widespread marine biodiversity loss.
  • D. 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.
  • E. Chicxulub impact crater
    The Chicxulub impact crater is a massive buried structure in Mexico’s Yucatán Peninsula formed by an asteroid impact widely linked to the mass extinction event that wiped out the non-avian dinosaurs.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
