How this entity was disambiguated
This entity first appeared as the object of triple T16413473 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: Darriwilian Stage Context triple: [Middle Ordovician, containsStage, Darriwilian Stage]
-
A.
Asselian Stage
The Asselian Stage is the earliest stage of the Permian Period, marking the transition from the Carboniferous and characterized by distinctive marine and terrestrial fossil assemblages used for global stratigraphic correlation.
-
B.
Ludfordian Age
The Ludfordian Age is a late Silurian time interval characterized by significant marine biodiversity changes and notable graptolite and conodont fossil assemblages.
-
C.
Aquitanian Stage
The Aquitanian Stage is the earliest age of the Miocene Epoch, marking a distinct interval in Earth’s geologic time characterized by significant climatic and faunal transitions.
-
D.
Rhaetian Stage
The Rhaetian Stage is the final stage of the Late Triassic period, marked by significant marine extinctions and preceding the Triassic–Jurassic boundary.
-
E.
Famennian stage
The Famennian stage is the final stage of the Late Devonian Period, marked by significant evolutionary turnover and recovery following major extinction events.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
