The Museum of Natural History

           Today, I went to the Museum of Natural History. I thought it was kind of fun but also scary because of the fake-dinosaur bones. But, it was also extremely fun because I got to know a lot about the universe, and the dinosaurs. First, I thought this was interesting, but do you know what a Pangaea is? A Pangaea is continents, such as Earth, Uranus, and Neptune, and so on connected together as a land. Also, in the space, there are 9planets total, (starting closest from the sun,) 1.Sun 2.Mercury 3.Venus 4.Earth 5.Mars 6.Jupiter 7.Saturn 8.Uranus 9.Neptune, but Pluto, a planet which rotated from the Sun, suddenly did not rotate around the Sun, so it was not one of a Solar System anymore.

           In our History from Earth was born, we had 4 eras until now, and in the Precambrian Era, bacteria and cells lived, and one of the living cells were the Cyanobacteria which produced oxygen through the photosynthesis. In the Paleozoic Era, only reptiles lived, and in the Mesozoic Era, the dinosaurs lived eating lots and lots of interesting things. Also, the Cenozoic Era, which also means today, has lots of animals living, such as human and other mammals.
