Paleozoic mass extinctions

Target entity: Paleozoic mass extinctions
Context triple: [Kellwasser events, partOf, Paleozoic mass extinctions]

• A. 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.
• B. Late Ordovician mass extinction
  The Late Ordovician mass extinction was one of Earth’s largest biodiversity crises, during which severe climate change and glaciation led to the rapid loss of a substantial portion of marine species.
• 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. Catastrophes and Lesser Calamities: The Causes of Mass Extinctions
  *Catastrophes and Lesser Calamities: The Causes of Mass Extinctions* is a scientific book by geologist Anthony Hallam that examines the geological and biological evidence behind major extinction events in Earth's history.
• 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. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Paleozoic mass extinctions
Target entity description: Paleozoic mass extinctions were several major biodiversity crises between roughly 541 and 252 million years ago that dramatically reshaped marine and terrestrial life, including events like the Kellwasser extinctions and culminating in the end-Permian “Great Dying.”
