大阪駅にひそむ3億5千万年前 Silence of 350 Million Years in Osaka Station
A large numberof people crisscross in the JR Osaka Station Center Concourse in a busy fashion. The passage is supported by many stout pillars. Once you slow down your steps and stop at any one of them, you are sure to find the ammonites of some 350 million years old on the stone tiles.
