The study of Oshigatamon pottery with Yoriitomon culture

对绳纹陶器的研究一直是围绕绳纹文化的起源展开的。要弄清绳纹陶器的起源，就必须弄清绳纹陶器的年代顺序。第一个拿到钥匙的是，我们两次在千叶肯Katorigun Omigawacho的Shironodai贝壳堆中发现了Yoriitomon陶器和Chinsenmon陶器。（1989, 1990）该贝丘是绳纹时代早期著名而罕见的贝丘之一，为东京大学人类学研究小组（1944）和吉田一雄先生（1949,1950）的研究发掘提供了重要的日期。在研究挖掘中，我们没有发现Oshigatamon陶器。但我们可以找到由堀门陶器到Shibonokuchi陶器的年代。这是一个值得注意的案件，可以找到两具遗骸（Tadokaso类型）。此次发掘结果为绳纹时代早期的年代学研究和日语的起源提供了依据。今年，我们编制了《考古遗存分组整理报告》，并将研究发掘的成果分两次放在了小野代贝丘上。首先对许多陶器进行了整理，并根据地层位置和类型对考古遗迹进行了分组，绘制了板片、拓片、横截面。（七十个盘子）我们雕刻石头，测量，描画，绘制盘子。绘制了考古地形图和地层位置图，我们有了完整的板块，这是报告所必需的。该报告将于今年年底前以《千叶斋野代贝壳丘报告》的形式发表。

The study of Oshigatamon pottery is always doing research with origin of Jomon culture. We must clear up the relation of chronological sequence to Yoriitomon pottery for solve origin of Jomon pottery. The first to get the key, we researched for twice Shironodai shellmound at Chibaken Katorigun Omigawacho found Yoriitomon pottery and Chinsenmon pottery. (1989, 1990)This shellmound is one of famous and rare in early Jomon age, with offer important date of research excavation by anthropological team in Tokyo univ, (1944)and Mr. Itaru Yoshida(1949, 1950).We could not discover Oshigatamon pottery at the research excavation. But we couId get dates from Yoriitomon poterry to Shibonokuchi pottery. And this is a case worthy of notice to get two human remains(Tadokaso type).The result of this excavation offer the date of chronological study in early Jomon age and origin of Japanese.This year we drew up the archaelogical remains report of grouping and arranging to put good result of research excavation at Shironodai shellmound for twice.The first we arranged many potteries and grouped archaelogical remains according to stratigraphy position and type and draw up plate, rubbings, cross section. (seventy plates)We carved stones and measured and traced and draw up plate. Drawing up maps of archaeological features and stratigraphy position, we had complete set of plates which is necessary for report. That report will be published as the Report of Chibaken Shironodai shellmound before the end of the year.
