Triassic–Jurassic extinction event
E201672
The Triassic–Jurassic extinction event was a major mass extinction around 201 million years ago that wiped out many marine and terrestrial species, paving the way for dinosaurs to become the dominant land animals in the Jurassic Period.

How this entity was disambiguated
This entity first appeared as the object of triple T1772748 — 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: Triassic–Jurassic extinction event Context triple: [Triassic, endsWith, Triassic–Jurassic extinction event]
-
A.
Permian–Triassic mass extinction
The Permian–Triassic mass extinction was the most severe biodiversity crisis in Earth's history, wiping out the majority of marine and terrestrial species around 252 million years ago and marking the boundary between the Paleozoic and Mesozoic eras.
-
B.
Late Devonian extinction
The Late Devonian extinction was a prolonged series of biodiversity crises around 375–359 million years ago that devastated marine life, especially reef ecosystems and armored fishes, and ranks among the largest mass extinctions in Earth’s history.
-
C.
Cretaceous–Paleogene boundary
The Cretaceous–Paleogene boundary marks the geological transition 66 million years ago associated with a mass extinction event that wiped out non-avian dinosaurs and many other species, likely triggered by a large asteroid impact.
-
D.
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.
-
E.
Jurassic Period
The Jurassic Period was a major division of the Mesozoic Era characterized by warm climates, the dominance and diversification of dinosaurs, and the early evolution of birds.
- 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: Triassic–Jurassic extinction event Description of subject: The Triassic–Jurassic extinction event was a major mass extinction around 201 million years ago that wiped out many marine and terrestrial species, paving the way for dinosaurs to become the dominant land animals in the Jurassic Period.
