How this entity was disambiguated
This entity first appeared as the object of triple T16171368 — 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.

-
A.
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.
-
B.
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.
-
C.
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.
-
D.
Givetian stage
The Givetian stage is a middle subdivision of the Devonian Period characterized by significant marine biodiversity and reef development before the late Devonian extinction events.
-
E.
Ludfordian Age
The Ludfordian Age is a late Silurian time interval characterized by significant marine biodiversity changes and notable graptolite and conodont fossil assemblages.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
