(It was identified as a wooden artifact in March of 1986.) It is 26.9 cm long, 5.0 cm at its widest point, and between 3 and 7 mm thick. The sides are parallel for the length of the object until at one end one edge remains straight while the other narrows to meet it forming a point. The object becomes thinner toward the point as well. On both flat sides are oval indentations lined up like fish scales. The piece of wood is cut from the tree vertically, along the grain.\nThe wood has been identified as a species of Mulberry Cudrania tricuspidata, and is from a tree of at least 40 years in age. This sort of mulberry can exceed 8 meters in height. It grows in warm clinates and at present is distributed in China and on the Korean peninsula. It was brought by man to Japan about 100 years ago, but besides imported plants it is not known to exist in Japan anywhere but in the Nishiyagi Formation.\nThe object was probably made by splitting a log of straight-grained wood with a wedge and then shaping the resulting plank by whittling. The fact that one end has been thinned and shaped into a point makes one imagine that it was perhaps a spearhead or a kind of short sword.\nNo stone tools were recovered during this excavation. However after the end of the excavation the author had the opportunity to examine a stone tool which had been collected by KIHIRA Hajime from the lower part of the sand-gravel layer (Layer V) of the Nishiyagi Formation at a point just west of this excavation. This is a lamellar flake about 2.6 by 2.1 cm in size. It is of a yellowish-brown jasper. It can be deduced that the flake was struck from a squarish shaped core because of its flat striking platform, the large amount of natural cortex remaining, and the three faces on the back of the tool. On the edges are traces of microflaking but most are from secondary edge breakage caused by rolling.\nThe shape of this stone tool closely resembles that of a flake of andesite which was collected by the author in 1958 at the foot of the cliff outcrop of the Nishiyagi Formation at the Taniyagi Coast, 1.8 km southeast of the site of this 1985 excavation. The two flakes are probably representative tools for the same time period.\nThe fact that a wooden artifact and stone tools have been recovered from the Nishiyagi Formation confirms that humans lived in the area during the Pleistocene period. The dating of these finds at present cannot be narrowed to les than the wide range of between 50,000 and 90,000 years B. P. but a mores precise dating is being planned for the future.\nThe stone tools found not only resemble in many ways the numerous stone tools being excavated at present at the Babadan A sites in Miyagi prefecture, but also many examples discovered in China and Siberia. They are all most likely of Middle Paleolithic manufacture. The Nishiyagi Formation stone tools are most closely comparable with those from the top of Layer 10 at Babadan, which are dated to 50～60,000 years B.
