Dinosaurs are one of the most amazing creatures in the history of life on Earth. They lived and multiplied on Earth for about 160 million years, but eventually became extinct at the end of the Cretaceous period 65 million years ago.
Scientists have revealed many secrets about dinosaurs through the study of fossils and genetic information. Here are some of the more interesting discoveries:
1. Dinosaurs are not true reptiles: Although dinosaurs look similar to modern reptiles, they are actually closer to birds. Dinosaurs have feathers, hollow bones and other features that are characteristics of birds.
2. Dinosaurs may have very good eyesight: Dinosaurs' eyes are much larger than humans, and many species of dinosaurs have double or even triple lenses, which can see a wider field of view and more details.
3. Dinosaurs also laid eggs: All dinosaurs were oviparous, just like modern birds.
4. Most dinosaurs were omnivores: Although some dinosaurs, such as Tyrannosaurus Rex, were carnivores, most dinosaurs were omnivores, eating grass, plants, and small animals.
5. Dinosaurs may have been able to incubate their own eggs: The eggshells of dinosaurs were very strong, so they could bury their eggs in the ground or use their body temperature to incubate them.
These discoveries are only part of the secrets of dinosaurs. With the continuous advancement of science and technology, we believe that more mysteries about dinosaurs will be revealed in the future.
