Phrase: Cretaceous–Paleogene boundary | Statement: [Cretaceous, hasBoundaryEvent, Cretaceous–Paleogene boundary]

Target entity: Cretaceous–Paleogene boundary
Context triple: [Cretaceous, hasBoundaryEvent, Cretaceous–Paleogene boundary]

• A. Cretaceous
  The Cretaceous was the final period of the Mesozoic Era, marked by high sea levels, diverse dinosaurs, and ending with the mass extinction that wiped them out about 66 million years ago.
• B. Pliocene epoch
  The Pliocene epoch was a geological time period roughly 5.3 to 2.6 million years ago marked by cooler global climates, the expansion of grasslands, and significant evolutionary developments among mammals and early hominins.
• C. Deccan Traps volcanism
  Deccan Traps volcanism refers to one of Earth’s largest known volcanic flood basalt events in western India, linked to mass extinction and major climatic changes near the end of the Cretaceous period.
• D. Jurassic
  Jurassic is a geologic period of the Mesozoic Era known for its abundant dinosaurs and the breakup of the supercontinent Pangaea.
• E. The Endangered Earth
  The Endangered Earth is the collective representation of the planet’s environmental crisis, recognized by Time as a symbolic “Person of the Year” to highlight global ecological threats and the urgency of conservation.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity.

Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"

Entity: Cretaceous–Paleogene boundary
Triple: [Cretaceous, hasBoundaryEvent, 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.
