Dinosaurs ruled the Earth for more than 100 million years. This time span occupies about one-third of the Earth's entire geological epoch, much longer than the time of human existence. Dinosaurs first appeared around 2300 million years ago, it underwent a long evolutionary process and finally became extinct about 65 million years ago.
Over the course of more than 100 million years, dinosaurs have undergone a variety of changes and adaptations, from the original herbivorous dinosaurs to the later carnivorous dinosaurs, and from land to water, dinosaur niches are everywhere.
However, despite the fact that dinosaurs have ruled the earth for so long, there is still much we know about them. Although we have discovered a large number of dinosaur fossils, there is still much unknown about the physiology, ecology, and behavior of dinosaurs. For example, we are still not sure how dinosaurs communicated, nor are we clear about the specific reasons for their extinction. Solving these questions will help us better understand this group of organisms that have disappeared.
In conclusion, dinosaurs are one of the most successful creatures in the history of the earth, and their existence and evolution have had a profound impact on the earth's ecosystem and biodiversity. By studying dinosaurs, we can better understand the history and future of the planet, while also providing valuable information for our biology and ecology. Autumn and Winter Check-in Challenge
