| Study 1st lecture Class in Fossils |
| The earth was born at about 4.6 billion years ago, and life on the earth arose at about 4.0 billion years ago. The oldest fossils of the world are minute cells of bacteria-like organisms at about 3.5 billion years ago. During the long history of life, a great amount of organisms appeared on the earth as a result of repetitions of evolution and extinction. We are able to know the history of the many organisms as fossils. Fossils are remnants, impressions, or traces of ancient organisms, preserved mainly in sedimentary rocks. In our "geobox", we produced the five chocolate replicas, which are made from genuine fossil specimens registered at the Geological Museum of the Geoligical Survey of Japan (GSJ), AIST. Original fossils, registered and housed at the Geological Museum of GSJ. You can observe abundant specimens such as fossils, minerals and rocks at the museums of natural history. Let's go there to study the history of the earth and life!
