I was really shocked by these huge fossils when I stepped into the museum at the first time. I feel that humans are so tiny. Compared with those ancient creatures, we are so fragile. However, I also believe that size does not mean anything; human is the most powerful species in the world because we have the capability of thinking and creating.
I do not think I can understand the natural world by any other medium because the fossils are so intuitive. Fossils are books that show us the evolution of the earth.
