Target entity: Hangenberg event Context triple: [Late Devonian extinction, includesEvent, 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.
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.
-
C.
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.
-
D.
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.
-
E.
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.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
