Subject Phanerozoic mass extinctions E415306 entity
Predicate hasPart P35 FINISHED
Object Cretaceous–Paleogene mass extinction
The Cretaceous–Paleogene mass extinction was a catastrophic global event about 66 million years ago, most famous for wiping out the non-avian dinosaurs along with many other species, likely triggered by a massive asteroid impact and associated environmental upheavals.

Target entity: Cretaceous–Paleogene mass extinction
Context triple: [Phanerozoic mass extinctions, hasPart, Cretaceous–Paleogene mass extinction]
  • A. 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.
  • B. 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.
  • 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. Phanerozoic mass extinctions
    Phanerozoic mass extinctions are the handful of catastrophic, globally disruptive biodiversity crises over the last ~540 million years that abruptly wiped out large proportions of Earth’s species and reshaped the course of evolution.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
