Target entity: subcommission on Carboniferous stratigraphy Context triple: [International Commission on Stratigraphy, hasPart, subcommission on Carboniferous stratigraphy]
-
A.
Magnesian Limestone succession
The Magnesian Limestone succession is a geological sequence of Permian-age dolomitic limestone formations that forms a distinctive belt across parts of northern and central England.
-
B.
Lomagundi–Jatuli carbon isotope excursion
The Lomagundi–Jatuli carbon isotope excursion was a major global perturbation in the carbon cycle during the Paleoproterozoic, marked by unusually high carbon isotope ratios that suggest prolonged burial of organic carbon and significant changes in Earth’s atmosphere and oceans.
-
C.
Kellaways Formation
The Kellaways Formation is a Middle Jurassic geological formation in England composed mainly of sandstones and mudstones, representing shallow marine and deltaic environments.
-
D.
International Chronostratigraphic Chart
The International Chronostratigraphic Chart is the globally recognized standard timeline used by geologists to define and correlate the divisions of Earth’s geological history.
-
E.
Summerville Formation
The Summerville Formation is a Late Jurassic sedimentary rock unit in the western United States, characterized by thin-bedded mudstones and sandstones deposited in tidal flat and coastal environments.
- 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.
