How this entity was disambiguated
This entity first appeared as the object of triple T3843539 — 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.

Triassic
The Triassic was the first period of the Mesozoic Era, marked by the initial diversification of dinosaurs and the recovery of life following the Permian–Triassic mass extinction.

The Siderian Period is the earliest division of the Paleoproterozoic, marked by widespread banded iron formation deposition and the initial rise of atmospheric oxygen on Earth.
-
D.
Calymmian Period
The Calymmian Period is the earliest division of the Mesoproterozoic Era, marked by the stabilization and expansion of continental crust and the development of large sedimentary basins roughly 1.6 to 1.4 billion years ago.
-
E.
Rhyacian Period
The Rhyacian Period is a geologic time interval in the early Proterozoic characterized by significant crustal growth, widespread metamorphism, and some of the earliest known large-scale glaciations.

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
