Two macaque fossil teeth from the Japanese Pleistocene

Two fossil teeth of the Pleistocene macaque of Japan are stated to be those ofMacaca cf.fuscata. One of them is a lower canine tooth found in the Shiriya mine in northern Japan. It has been thought that the fossil assemblage of the Shiriya mine is of the late Pleistocene. The canine concerned is not distinguishable from the lower right one of the living female Japanese monkey. The other is a lower molar taken from the Ando quarry in western Japan. The fossil assemblage from the Ando quarry or from sites neighbouring the quarry indicates that the age of the molar can be traced back to the middle Pleistocene. The molar concerned has a somewhat buccolingually depressed crown as compared with that of the living Japanese monkey (Macaca fuscata).
