A large shell mound called Mazukari shell-mound (YAMASHITA, 1978) was found in 1978 to be buried 12m under the ground surface, at Utsumi Town in the south part of the Chita Peninsula, Aichi Prefecture in Central Japan.
Several hundred pieces of Kozanji-type pottery (the middle Earliest Stage of Jomon Age) are included in the collected remains. Tegillara granosa, dated at 8, 330±260y.B.P. (GaK-7950) occurred with these potteries. Many kinds of fossil shells, foraminifers as well as Akahoya Tephra (about 6, 300y.B.P.) were found in the Mazukari shell mound. These features and the 14C dating suggest that the sediments were formed by Jomon Transgression.
There are Hayashinomine shell-mound, Shimizunoue shell-mound, Otofukudani remains and Shimobessho are near the Mazukari shell-mound. The following sea-level changes since 9, 000y.B.P. are deduced from the elevation of these remains and the upper limit of marine the sediments.
ca. 9, 000y.B.P. ca-14m
ca. 7, 000y.B.P. ca+1m
ca. 6, 000y.B.P. ca+4.5-5.0m
ca. 4, 500y.B.P. ca+1m
ca. 3, 000y.B.P. ca+2m
