 note = {Mt. Kikuishi (1,209 m) is one of the peaks on the Tsugami Shindō Trail. The name was coined in reference to the ammonoids (Kikuishi) discovered here by the late Dr. Ken Ono who lead the creation of the trail in the 1960's. The geology on the trail around the Mt. Kikuishi fossil locality has not been studied in detail yet. We carried out geological research and fossil collection on 20 September and 23-24 October in 2021. Careful searching for fossils in the Teradani Formation exposed around the trail made a successful finding of many molluscan fossils including bivalves, gastropods and ammonoids which include Canavaria sp. The significance of the occurrence of these molluscan fossils is pointed out.},
