Target entity: International Chronostratigraphic Chart
Context triple: [Cretaceous–Paleogene boundary, locatedInTimeScale, International Chronostratigraphic Chart]
  • A. International Commission on Stratigraphy
    The International Commission on Stratigraphy is the global scientific authority responsible for defining and standardizing the geological time scale and stratigraphic units used in Earth sciences.
  • B. 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.
  • C. International Atomic Time
    International Atomic Time is a high-precision time standard based on the combined output of atomic clocks worldwide, serving as the fundamental reference for modern civil and scientific timekeeping.
  • D. 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.
  • E. The Geological Evidence of the Antiquity of Man
    The Geological Evidence of the Antiquity of Man is an 1863 scientific work by Charles Lyell that marshals geological and fossil evidence to argue for the great age of humanity and to support evolutionary ideas.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
