How this entity was disambiguated
This entity first appeared as the object of triple T11115219 — 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: Aquitanian Stage Context triple: [Lemme-Carrosio section, timeScaleUnitDefined, Aquitanian Stage]
-
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.
Cisuralian Epoch
The Cisuralian Epoch is the earliest subdivision of the Permian, marking a time of significant diversification of terrestrial life and continued development of early amniotes following the late Paleozoic ice age.

C.
Pridoli Epoch
The Pridoli Epoch is the final epoch of the Silurian Period, marking a transitional interval in Earth’s history just before the onset of the Devonian.
-
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.
Terreneuvian
The Terreneuvian is the earliest age of the Cambrian Period, marking the beginning of the Phanerozoic Eon and the widespread appearance of complex animal life in the fossil record.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: Aquitanian Stage Description of subject: 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.
