 note = {A specimen of fossil fish was obtained from the Sakuraguchidani Mudstone Member of the Nishinakayama Formation, the Toyora Group. The fossil-bearing horizon, 23-1, is laminated black mudstone with abundant fossil woods and pyrite granules. On the basis of ammonoid biostratigraphic research, this horizon corresponds to the base of the Harpoceras inouyei Zone, which is correlated to the base of the Exaratum Standard Subzone, middle part of the Lower Toarcian. The present specimen, one of rare occurrences of fish vertebrae, could contribute to tracing the evolutionary history of Early Jurassic fish in the Panthalassa.},
