How this entity was disambiguated
This entity first appeared as the object of triple T8356669 — 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: Carnian age Context triple: [Late Triassic, startBoundary, Carnian age]
-
A.
Guadalupian Epoch
The Guadalupian Epoch is a middle subdivision of the Permian characterized by significant marine biodiversity followed by major ecological changes leading toward the end-Permian mass extinction.
-
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.
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.
-
D.
Late Triassic
The Late Triassic was a geologic period and epoch, roughly 237–201 million years ago, marked by the diversification of early dinosaurs and the end-Triassic mass extinction that paved the way for Jurassic ecosystems.
-
E.
Siderian Period
The Siderian Period is the earliest division of the Paleoproterozoic, marked by widespread banded iron formation deposition and the initial rise of atmospheric oxygen on Earth.
- 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
