How this entity was disambiguated
This entity first appeared as the object of triple T8356792 — 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: Panthalassa Ocean margins Context triple: [Toarcian Oceanic Anoxic Event, hasGlobalExtent, Panthalassa Ocean margins]
-
A.
Eurasian continental margin
The Eurasian continental margin is the submerged edge of the Eurasian tectonic plate, extending from its coastal shelves into the deep Arctic and Atlantic oceans and encompassing features such as the Chukchi Plateau.
-
B.
North Atlantic plate boundary system
The North Atlantic plate boundary system is the complex tectonic zone where the North American, Eurasian, and related plates interact through mid-ocean ridges, fracture zones, and transform faults across the North Atlantic Ocean.
-
C.
East Pacific tectonic system
The East Pacific tectonic system is a major geological region in the eastern Pacific Ocean characterized by active seafloor spreading, transform faults, and subduction zones that shape the surrounding oceanic plates and continental margins.
-
D.
North Atlantic fracture zone system
The North Atlantic fracture zone system is a network of major oceanic crustal faults and offsets that segment the Mid-Atlantic Ridge and shape the seafloor topography of the North Atlantic Ocean.
-
E.
passive margin of Gondwana
The passive margin of Gondwana was the long, tectonically quiet continental edge of the ancient supercontinent Gondwana, where thick sedimentary sequences accumulated and from which various microcontinents, such as Avalonia, later rifted away.
- 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: Panthalassa Ocean margins Description of subject: The Panthalassa Ocean margins were the extensive continental and volcanic arc boundaries of the vast Panthalassa superocean that surrounded the supercontinent Pangaea during much of the Mesozoic Era.
