抄録

The Japanese hare, Lepus brachyurus, was one of the most abundant species among the mammalian bone remains excavated from the lower part of the rockshelter site at Tochibara, Nagano Prefecture, Japan. The greater part of this archaeological site belongs to the earliest Jomon period and the age of its lower part was indicated as 8, 500-9, 000 years B. P. by carbon-14 determination.<BR>The size and proportion of the teeth and skull were compared between prehistoric and recent populations of the hare. Recent materials were collected from the eastern part of Nagano Pref. adjacent to Tochibara site.<BR>Mesiodistal (MD) and buccolingual (BL) crown diameters of the cheek teeth were generally larger in the prehistoric hare. The chronological size differences of these parameters had a tendency to become larger in the middle part of cheek teeth rows and smaller in incisors and both ends of the cheek teeth rows.<BR>Lower temperature of the earliest Jomon period was suggested to be one of the most important factors that caused the size differences between the two chronological hare populations
