How this entity was disambiguated
This entity first appeared as the object of triple T16271821 — 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: Frasnian Age Context triple: [Late Devonian, contains, Frasnian Age]
-
A.
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.
-
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.
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.
-
D.
Imbrian period
The Imbrian period is a major lunar geologic era characterized by extensive mare volcanism and large impact basins that shaped much of the Moon’s visible surface.
-
E.
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.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
