Abstract

A theropod tooth found in the Upper Cretaceous Himenoura Group in the Koshikijima Islands, Kagoshima Prefecture, is described. Recent paleontological work in the region suggests a middle Campanian age for the specimen. Lacking a feature diagnostic of any specific theropod clade, this specimen is considered merely as Theropoda incertae sedis. The present finding confirms the potential of the Himenoura Group as a new source of information on the diversity of Theropoda during the Campanian.
