Tetori Group (Yokoyama, 1895)

The terrestrial strata in Gifu pref. - Toyama pref. was separated as Jinzu Group, the Bathonian - Oxfordian marine strata in Fukui pref. - Gifu pref. was separated as Kuzuryu Group, and the strata intercalating the Tithonian and Oxfordian marine horizons was separated as Managawa group but the discussion is still ongoing.
