Toarcian

Target entity: Toarcian
Context triple: [Early Jurassic, contains, Toarcian]

• A. Pliensbachian
  The Pliensbachian is a stage of the Early Jurassic period characterized by distinctive marine faunas and important ammonite biostratigraphy.
• B. Maastrichtian
  The Maastrichtian is the final stage of the Late Cretaceous period, marking the last interval of non-avian dinosaur dominance before the mass extinction event 66 million years ago.
• C. Early Jurassic
  The Early Jurassic was the first epoch of the Jurassic Period, marked by the recovery of life after the end-Triassic extinction and the early diversification of dinosaurs and marine reptiles.
• D. 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.
• E. Late Triassic
  The Late Triassic was a geologic period and epoch, roughly 237–201 million years ago, marked by the diversification of early dinosaurs and the end-Triassic mass extinction that paved the way for Jurassic ecosystems.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
