| Research Abstract |
The Mesozoic echinoid fauna of Japan comprises its own endemic species of the genera mostly derived from Circum-Mediterranean faunas and apparently has no direct affinity to North American faunas. Towards the end of the Cretaceous the Japanese fauna has close ties to Indo-Madagascar faunas with some its own endemic genera. In the Cenozoic, through the Oligocene-Eocene event a distinctive fauna adapted to the Temperate Zone of North-West Pacific region developed around Japan. In the Miocene this fauna was reduced and became restricted to Japan Sea by the warm event and the opening of the Japan Sea, and a new endemic fauna developed on the Pacific coast. The Pleistocene climate change caused the Japan Sea fauna to be extinct and replaced by the Pacific coast fauna.
