There are no real dinosaurs in the modern world, as they became extinct at the end of the Cretaceous period 65 million years ago. However, we can learn about the appearance, behavior, and lifestyle of dinosaurs through fossil records and genetic information.
Fossils are one of the most important sources of paleontological information. They are relics of ancient life that have been preserved in a petrified form. Through the excavation and analysis of dinosaur fossils, scientists have been able to learn about the types, sizes, and behaviors of dinosaurs.
In addition, using modern scientific and technological means, in recent decades, humans have also restored the skeletons of many dinosaurs and made models that match their real size. These models are widely used in museums, theme parks and other places, allowing people to more intuitively feel what dinosaurs looked and felt like when they existed.
In summary, there are no real dinosaurs in the modern world, but we can learn about them through fossils and technological restorations.
