  • B. Late Devonian
    The Late Devonian was the final epoch of the Devonian Period, marked by extensive reef collapse, major evolutionary changes in fish and early land plants, and several significant mass extinction events.
  • C. Middle Devonian
    The Middle Devonian is a subdivision of the Devonian Period, dating to roughly 393–383 million years ago, marked by extensive marine life diversification and the continued evolution of early terrestrial ecosystems.
  • D. Late Ordovician
    The Late Ordovician was the final subdivision of the Ordovician Period, marked by extensive marine biodiversity followed by one of the largest mass extinction events in Earth's history.
  • E. Devonian Period
    The Devonian Period was a division of the Paleozoic Era characterized by the diversification of fish, the first significant colonization of land by plants and early tetrapods, and major reef-building in the oceans.
