Abstract

Abstract. Fusuline biostratigraphy and faunal composition of the upper part the Ichinotani Formation and lower part of the Mizuyagadani Formation in the Fukuji area, central Japan are reexamined and compared to those of previous works. The upper part of the Upper Member of the Ichinotani Formation is composed mainly of the upper Kasimovian and lower Gzhelian strata, and is characterized by the partial reappearance of Moscovian strata dominant in the lower part of the Upper Member, suggesting a more complicated geological structure of the formation than previously assumed. Fusulines apparently correlatable to the middle part of the Kasimovian have not been found in the Fukuji area. The species Carbonoschwagerina morikawai is restricted to the lower part of the Mizuyagadani Formation. Faunal composition and correlation of age-diagnostic fusuline species are reviewed paleobiogeographically between the Fukuji and other areas especially of the Akiyoshi Limestone. Described herein are two species of non-fusuline foraminifers and nine species of fusulines including Montiparus japonicus sp. nov.

日本中部飞驒边缘地体福地地区一野谷组和水谷谷组晚石炭世(kasimoviian和Gzhelian)的Fusulines

摘要重新研究了日本中部福城地区一野谷组上段和水谷组下段的富苏系生物地层学和动物组成，并与前人的研究成果进行了比较。一野谷组上段上部主要由上卡西莫瓦统和下格日连统地层组成，上段下部以部分莫斯科地层为主，表明该组地质构造比以前的假设更为复杂。在福岛地区未发现与卡西莫维安中部明显相关的Fusulines。Carbonoschwagerina morikawai种局限于水谷组下部。本文综述了福吉地区与其他地区特别是秋吉石灰岩地区的古生物地理特征。本文描述了2种非fusuline有孔虫和9种fusuline，包括Montiparus japonicus sp. nov。

期刊介绍： Paleonotological Research (PR) is a quarterly, peer-reviewed international journal, which focuses on original contributions primarily in the area of paleontology but also covering a wide range of allied sciences. It has been published since 1997 as a successor to the former journal Transactions and Proceedings of the Palaeontological Society of Japan. The emphasis of contributions will include global and local perspectives, and contents can cover all ages (Precambrian to the Quaternary, including the present time).
