Phrase: Maastrichtian | Statement: [SUE the T. rex, geologicalStage, Maastrichtian]

Target entity: Maastrichtian
Context triple: [SUE the T. rex, geologicalStage, Maastrichtian]

• A. Cretaceous
  The Cretaceous was the final period of the Mesozoic Era, marked by high sea levels, diverse dinosaurs, and ending with the mass extinction that wiped them out about 66 million years ago.
• B. Neogene
  The Neogene is a geologic period of the Cenozoic Era characterized by significant climatic cooling, the diversification of mammals and birds, and the emergence and evolution of early hominins.
• C. Paleogene
  The Paleogene is a geologic period that marks the beginning of the Cenozoic Era, characterized by the diversification of mammals and birds following the mass extinction that ended the age of dinosaurs.
• D. Pliocene epoch
  The Pliocene epoch was a geological time period roughly 5.3 to 2.6 million years ago marked by cooler global climates, the expansion of grasslands, and significant evolutionary developments among mammals and early hominins.
• E. Cenozoic
  The Cenozoic is the current geological era, beginning about 66 million years ago, characterized by the rise and diversification of mammals and birds and the formation of many modern mountain ranges and continents.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
