  • A. Rhaetian Stage
    The Rhaetian Stage is the final stage of the Late Triassic period, marked by significant marine extinctions and preceding the Triassic–Jurassic boundary.
  • B. Aquitanian Stage
    The Aquitanian Stage is the earliest age of the Miocene Epoch, marking a distinct interval in Earth’s geologic time characterized by significant climatic and faunal transitions.

    The Famennian stage is the final stage of the Late Devonian Period, marked by significant evolutionary turnover and recovery following major extinction events.
  • D. Givetian stage
    The Givetian stage is a middle subdivision of the Devonian Period characterized by significant marine biodiversity and reef development before the late Devonian extinction events.
  • E. Ludfordian Age
    The Ludfordian Age is a late Silurian time interval characterized by significant marine biodiversity changes and notable graptolite and conodont fossil assemblages.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
