Abstract

The writer summarized the recent progress of conodont research by himself and his collaborators. Conodonts have been found out from the Silurian, Carboniferous, Permian and Triassic sediments in various localities of the Japanese Islands. Most of these discoveries contribute new evidences for geochronology, biostratigraphy, geotectonics and geologic evolution of the Japanese Islands.
