Target entity: Triassic–Jurassic boundary Context triple: [Global Boundary Stratotype Section and Point for base of Hettangian, isGlobalStandardFor, Triassic–Jurassic boundary]
-
A.
Triassic–Jurassic extinction event
chosen
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.
-
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.
Givetian–Frasnian boundary
The Givetian–Frasnian boundary marks the internationally recognized stratigraphic transition between the Middle and Late Devonian periods, defined by specific fossil and sedimentary changes in the geologic record.
-
D.
Emsian–Eifelian boundary
The Emsian–Eifelian boundary marks the internationally recognized transition between the Early and Middle Devonian periods in the geologic timescale.
-
E.
Late Triassic
The Late Triassic was a geologic period and epoch, roughly 237–201 million years ago, marked by the diversification of early dinosaurs and the end-Triassic mass extinction that paved the way for Jurassic ecosystems.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
