Dinosaurs are among the oldest animals that have ever lived on Earth. They appeared on Earth about 240 million years ago and continued to exist until they became extinct about 65 million years ago. Dinosaurs came in all shapes and sizes, including the huge sauropods, carnivorous Tyrannosaurus, and Ceratops.
According to scientists, the extinction of dinosaurs may be related to factors such as natural disasters, climate change, and environmental pollution. The most widely accepted theory is that a meteorite impact event caused global climate change and a large-scale collapse of the ecosystem, which ultimately led to the extinction of the dinosaurs.
During the dinosaur era, the ecosystem on Earth was very different from today. For example, the land was much larger and there were no humans. Therefore, we can only understand these mysterious creatures through fossil records and scientific research.
Although dinosaurs are extinct, they still have a significant impact on our culture and science. Many people love dinosaurs and are interested in their life cycle and appearance. At the same time, the study of dinosaurs is also helping us better understand ecosystems and evolution.
