A fossil barbourisiid whalefish collected beside the Arakawa River, Aomori City, and believed to be from the Middle Miocene Wadagawa Formation, is described as a new genus and species, Miobarbourisia aomori in the family Barbourisiidae. The genus Miobarbourisia is more primitive to other whalefishes (including Barbourisia) in having large, long pelvic fins, a more anterior dorsal fin and an anal fin far behind the origin of the dorsal fin. This specimen is the first whalefish fossil discovered worldwide.
