A rostrum of a suliform bird from the Lower Oligocene Yamaga Formation of Ashiya Group in Ainoshima Island, Fukuoka Prefecture, Kyushu, southwestern Japan is briefly described. The present specimen (KMNH VP 600013) is slender and flat, with a strongly curved rostral tip, a sharply-defined longitudinal groove, and apertura nasi ossea that were likely extremely reduced or absent.
