Fossils of Cervus sp. from the Lower Pleistocene Kasumi Formation of the Kazusa Group, Akishima, Tokyo, Japan

Abstract

Postcranial fossils of Cervus sp. (Mammalia, Artiodactyla, Cervidae) newly collected from the lower Pleistocene (ca. 2.00–1.95 Ma) Kasumi Formation of the Kazusa Group, Akishima, Tokyo, Japan are described in this study. They consist of a right radius, right ulna, left metacarpal, and left tibia of a single individual. This individual is probably subadult because of the incompletely fused epiphyses. It is morphologically well comparable to those of living sika deer (Cervus (Sika) nippon) and is smaller in size than those of living Père David’s deer (Elaphurus davidianus).
