Last Glacial Period
E675171
The Last Glacial Period was the most recent major ice age, spanning roughly 115,000 to 11,700 years ago, during which large ice sheets covered vast areas of North America, Europe, and Asia and global climates were significantly colder and drier than today.

How this entity was disambiguated
This entity first appeared as the object of triple T7581442 — 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: Last Glacial Period Context triple: [Last Glacial Maximum, partOf, Last Glacial Period]
-
A.
Last Glacial Maximum
The Last Glacial Maximum was the most recent period in Earth’s history when ice sheets reached their greatest extent, dramatically lowering sea levels and reshaping global climates and ecosystems.
-
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.
Pleistocene epoch
The Pleistocene epoch was a geological time period characterized by repeated ice ages, widespread glaciation, and the evolution and global spread of modern humans.
-
D.
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.
-
E.
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.
- 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.
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.
