  The Lochkovian Epoch is the earliest subdivision of the Devonian Period, marking a time of significant diversification in early fish and terrestrial ecosystems.
• D. Hettangian stage
  The Hettangian stage is the earliest age of the Jurassic Period, marking the beginning of the Mesozoic era’s Jurassic system in the geologic time scale.
• E. Pridoli Epoch
  The Pridoli Epoch is the final epoch of the Silurian Period, marking a transitional interval in Earth’s history just before the onset of the Devonian.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
