How this entity was disambiguated
This entity first appeared as the object of triple T9462782 — 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: Kaigas glaciation Context triple: [Sturtian glaciation, follows, Kaigas glaciation]
-
A.
Gaskiers glaciation
Gaskiers glaciation was a brief but intense Neoproterozoic ice age, occurring around 580 million years ago, that is associated with widespread glacial deposits and may have influenced early animal evolution.
-
B.
Saalian glaciation
The Saalian glaciation was a major Middle Pleistocene ice age in northern Europe, during which extensive ice sheets covered large parts of the continent.
-
C.
Würm glaciation
The Würm glaciation was the last major glacial period of the Pleistocene in the Alps, marked by extensive ice coverage and shaping much of the region’s modern landscape.
-
D.
Marinoan glaciation
The Marinoan glaciation was a major Neoproterozoic ice age, likely a global or near-global “Snowball Earth” event that occurred around 650–635 million years ago.
-
E.
Huronian glaciation
The Huronian glaciation was one of Earth's earliest and longest ice ages, occurring over 2.4 billion years ago and likely linked to the Great Oxidation Event and major climatic shifts.
- 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: Kaigas glaciation Description of subject: The Kaigas glaciation was an early Neoproterozoic ice age event in Earth's history, preceding the more extensive Sturtian glaciation and representing one of the planet's significant pre-Cryogenian glacial episodes.
