Today, I went to the Seodaemun Museum of Natural History. There were lots of imformative and interesting things. The Universe was born about 15 billion years ago during the Big Bang. Then, when was the earth formed? About 4.6 years ago, the planet we live on, Earth, was formed. A long time ago, the continents were connected as one-piece od land. This is called Pangaea. I also saw the fossils of the ancient living things and the dianosaur's egg fossil. Cyanobacteria are living cells that produce oxygen through photosynthesis. Since these little cells filled the Earth with oxygen, there were various living things. About the dianosaurs, there are Carnivorous and Herbivorous. Carnivorous eat meat, Herbivorous eat grass. Interesting things is that, Troodon had the most advanced brains in the dianosaurs. We watched 3D movie. The main character name was Dinky. He is dianosaur. It was cooler than outside, it was good.
