Extinction: Tyrannosaurus rex lived at the end of the Cretaceous period, about 65 million years ago. With the Cretaceous-Tertiary extinction event, many dinosaur species such as Tyrannosaurus rex became extinct.
Scientific research: Tyrannosaurus rex is an important object in paleontological research. By studying its fossils, scientists have learned about the ecology and evolutionary history of dinosaurs.
Cultural impact: Tyrannosaurus rex is one of the most popular and well-known dinosaurs. It plays an important role in culture and often appears in movies, books and other media works, becoming one of people's representative images of dinosaurs.
Overall, Tyrannosaurus rex was a large and powerful dinosaur that was one of the most threatening predators on Earth during the late Cretaceous period. Although there is only one known species of Tyrannosaurus rex, its importance in paleontological research and influence in culture cannot be ignored.
