Neoproterozoic supercontinent cycle
E223836
The Neoproterozoic supercontinent cycle refers to the sequence of assembly and breakup of supercontinents during the Neoproterozoic Era, including the formation and fragmentation of Rodinia and the tectonic, climatic, and biological changes associated with these events.

How this entity was disambiguated
This entity first appeared as the object of triple T2000572 — 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: Neoproterozoic supercontinent cycle Context triple: [Rodinia, partOf, Neoproterozoic supercontinent cycle]
-
A.
supercontinent Rodinia
Rodinia was an ancient supercontinent that assembled during the Proterozoic Eon and existed before the later supercontinent Pangaea, profoundly influencing Earth’s early tectonic and climatic evolution.
-
B.
supercontinent Pannotia
Supercontinent Pannotia was a short-lived late Proterozoic landmass that assembled near the end of the Precambrian and preceded the formation of the better-known supercontinent Pangaea.
-
C.
Snowball Earth glaciations
Snowball Earth glaciations were extreme global-scale ice ages in the Precambrian when ice sheets may have covered most or all of Earth’s surface for millions of years.
-
D.
supercontinent Pangaea
Pangaea was a massive supercontinent that existed during the late Paleozoic and early Mesozoic eras, when nearly all of Earth's landmasses were joined together before breaking apart into the continents we know today.
-
E.
Great Ordovician Biodiversification Event
The Great Ordovician Biodiversification Event was a profound evolutionary radiation during the Ordovician Period that saw a dramatic increase in marine biodiversity and the establishment of many major animal groups in Paleozoic oceans.
- 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.
Subject: Neoproterozoic supercontinent cycle Description of subject: The Neoproterozoic supercontinent cycle refers to the sequence of assembly and breakup of supercontinents during the Neoproterozoic Era, including the formation and fragmentation of Rodinia and the tectonic, climatic, and biological changes associated with these events.
