Target entity: Hangenberg event
Context triple: [Late Devonian, hasMajorEvent, Hangenberg event]
  • 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. 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.
  • 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. 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.
  • E. Late Devonian extinction chosen
    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.
