Target entity: Darriwilian Context triple: [Middle Ordovician, hasSubdivision, Darriwilian]
-
A.
Eifelian
Eifelian is a stage of the Middle Devonian period characterized by significant marine biodiversity and the evolution of early reef ecosystems.
-
B.
Calymmian Period
The Calymmian Period is the earliest division of the Mesoproterozoic Era, marked by the stabilization and expansion of continental crust and the development of large sedimentary basins roughly 1.6 to 1.4 billion years ago.
-
C.
Rhaetian age
The Rhaetian age is the final stage of the Late Triassic period, marked by significant marine extinctions and major environmental changes that preceded the Triassic–Jurassic mass extinction.
-
D.
Ludfordian Age
The Ludfordian Age is a late Silurian time interval characterized by significant marine biodiversity changes and notable graptolite and conodont fossil assemblages.
-
E.
Statherian Period
The Statherian Period is the final division of the Paleoproterozoic Era, marked by the stabilization of continental cratons and significant crustal growth roughly 1.8 to 1.6 billion years ago.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
