Cambrian Series 2

Target entity: Cambrian Series 2
Context triple: [Terreneuvian, followedBy, Cambrian Series 2]

• A. Ordovician Period
  The Ordovician Period was a Paleozoic era interval marked by extensive marine biodiversity, the diversification of early vertebrates and invertebrates, and ending with one of Earth's major mass extinction events.
• B. Cambrian Period
  The Cambrian Period was an early division of geologic time marked by a rapid diversification of life known as the "Cambrian explosion," during which most major animal groups first appeared in the fossil record.
• C. Silurian
  The Silurian is a geologic period of the Paleozoic Era, roughly 443 to 419 million years ago, marked by the stabilization of Earth’s climate, widespread shallow seas, and significant diversification of early marine life and the first land plants.
• D. Middle Cambrian
  The Middle Cambrian is a subdivision of the Cambrian Period marked by diverse marine life and significant evolutionary developments, including many early arthropods and other complex organisms.
• 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.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
