Phrase: Cryogenian period | Statement: [Sturtian glaciation, partOf, Cryogenian period]

Target entity: Cryogenian period
Context triple: [Sturtian glaciation, partOf, Cryogenian period]

• A. Cryogenian Period chosen
  The Cryogenian Period was a geologic interval roughly 720–635 million years ago marked by some of the most extreme global glaciations in Earth’s history, when ice may have covered much of the planet.
