How this entity was disambiguated
This entity first appeared as the object of triple T335918 — 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: Ediacaran biota Context triple: [Proterozoic Eon, characterizedBy, Ediacaran biota]
-
A.
Proterozoic Eon
The Proterozoic Eon is a major division of Precambrian time, spanning from about 2.5 billion to 541 million years ago, marked by the buildup of atmospheric oxygen, the emergence of complex single-celled and early multicellular life, and the assembly of large continental landmasses.
-
B.
Paleozoic Era
The Paleozoic Era was an ancient geologic time interval, spanning roughly 541 to 252 million years ago, marked by the emergence and diversification of complex life in the seas and on land and the assembly of major continental landmasses.
-
C.
Phanerozoic Eon
The Phanerozoic Eon is the current and most recent major division of Earth's history, marked by abundant fossil evidence and the evolution and diversification of complex life forms, including plants, animals, and eventually humans.
-
D.
On the Imperfection of the Geological Record
"On the Imperfection of the Geological Record" is a chapter in Charles Darwin's *On the Origin of Species* that addresses why the fossil record is incomplete and how this affects evidence for evolutionary change.
-
E.
Life on Earth
Life on Earth is a landmark 1979 BBC nature documentary series, presented by David Attenborough, that explores the diversity and evolution of life across the planet.
- F. None of above. chosen

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: Ediacaran biota Description of subject: The Ediacaran biota comprises some of the earliest known complex multicellular organisms, featuring soft-bodied, enigmatic life forms that lived in the oceans before the Cambrian explosion.
