Target entity: Kellwasser event Context triple: [Late Devonian, hasMajorEvent, Kellwasser event]
-
A.
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.
-
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.
Kellwasser events
chosen
The Kellwasser events were two closely spaced Late Devonian mass extinction episodes that severely affected marine life, especially reef-building organisms and armored fishes, and contributed to a major restructuring of Paleozoic ecosystems.
-
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.
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.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
