Five hundred and forty million years ago, the earth was nothing but a bleak and desolate planet full of exploding volcanoes and thick gases, revolving silently in orbit.

However, in the following thirty million years, a world, which can only appear in our imaginations suddenly, burst forth from the depths of the vast oceans. If not for the multitude of fossils discovered millions of years later, who would have thought that a world full of strange and fantastic creatures once existed on the same earth that we live on now? This was a world full of vitality and an age that, while filled with slaughtering and the rank smell of blood, also brought about the evolution of life. If we had to choose one word to describe it, it would be “miraculous”. Welcome to this great age – the Cambrian.
