Messinian Salinity Crisis (late Miocene)
E262867
The Messinian Salinity Crisis (late Miocene) was a geological event during which the Mediterranean Sea nearly dried up after becoming isolated from the Atlantic, leading to massive salt deposition and dramatic environmental changes.

How this entity was disambiguated
This entity first appeared as the object of triple T2403598 — 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: Messinian Salinity Crisis (late Miocene) Context triple: [Neogene, hasMajorEvent, Messinian Salinity Crisis (late Miocene)]
-
A.
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.
-
B.
Younger Dryas cold event
The Younger Dryas cold event was a brief, abrupt return to near-glacial conditions about 12,900–11,700 years ago that interrupted the general warming trend at the end of the last Ice Age.
-
C.
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.
-
D.
Sturtian glaciation
The Sturtian glaciation was a major global ice age during the Neoproterozoic, when extensive ice sheets may have covered much of Earth’s surface in one of the most severe glacial events in the planet’s history.
-
E.
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.
- 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.
