How this entity was disambiguated
This entity first appeared as the object of triple T16081916 — 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.
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.
-
B.
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.
-
C.
Hettangian stage
The Hettangian stage is the earliest age of the Jurassic Period, marking the beginning of the Mesozoic era’s Jurassic system in the geologic time scale.
-
D.
Kimmeridgian stage
The Kimmeridgian stage is a division of the Late Jurassic period characterized by widespread marine sedimentation and important fossil-bearing strata used for global geological correlation.
-
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.
