ABSTRACT— Fusulinoidean specimens referable to the genus Misellina have been found in the con glomerate within the Dobaru Formation of the Lower Cretaceous Wakino Subgroup, Kitakyushu City, Fukuoka Prefecture,Japan. These species suggest that the limestone of this area had a close relation ship to the limestone of Southeastern Asiaand the Akiyoshi Limestone Group, Yamaguchi Prefecture, and that it could be considered as a limestone of the late Early Permian time of the Tethyan region. This paper describes the Misellina specimens from the Dobaru Formation.

aliciae, also described by Deprat (1912) but in Yun-nan, INTRODUCTION China The Paleozoic Yobuno Group (M. Ota el at, 1992; The present species were similarly discovered in a Nakae, 1998) is widely distributed in Kitakyushu City, and limestone cobble within the Dobaru Formation of the has a distribution in the western margin of the Akiyoshi Wakino Subgroup, at Hazegatoge, Kokuraminami Ward, Terrane, which is one ofJapanese PreJurassic terranes.

This paper faunas in other countries are very important for studies of deals with the systematic paleontology of these species. the continuity between Japanese terranes and neighbor ing ones, and discussing "paleo-Japan" in Carboniferous MISELLINA SPECIES FROM THE DOBARU and Permian times, and for clarifying the origin of the FORMATION AND ITS SIGNIFICANCE Japanese Islands. However, very little has been reported about fossils of the Yobuno Group because their fossils Over 60 species have been described under the are very rare and poorly preserved, owing to thermal genus Misellina since Schenck and Thompson established metamorphism in Late Cretaceous. Recently, Y. Ota the genus in 1940. Many species have been reported (2000, 2001, 2002) reported well-preserved fusulinoi- from several areas in the Tethyan region, and there have deans from conglomerates in the Lower Cretaceous been various discussions, for example about whether it is Dobaru Formation of the Wakino Subgroup, Kitakyushu the species of Misellina or not, Ozawa (1925a, b), Lee City. These fusulinoideans were derived from the under (1933), Kanmera (1957), Rauser (1963), Leven (1963, ling Paleozoic Yobuno Group and are very important 1982), Ozawa (1970), Choi (1972), Toriyama (1975), fossils for the reconstruction of paleo-Kitakyushu in Car Kobayashi (1977, 1997), Wang and Mu (1981), Sheng boniferous and Permian times. and Wang (1981), Yang (1985), Ueno (1991), Zhou and In this study of the Dobaru Formation, two types of Xie (1997) and so on. Misellina are discriminated in the specimens. One type Since Yabe presented his paper regarding the has a somewhat large shell, and seems to be referable to fusulinoideans of Mqji Ward in 1920, some other reports Misellina claudiae, which was originally described by have been of fusulinoidean species in Kitakyushu Deprat (1912) in Tou-Tchou-Chann, China and is a lead City.

The other type of Misellina has a Yabumoto (1998). Among them, only one species of rather small shell for this genus, and resembles Misellina the genus Misellina, Misellina cf. ovalis (Deprat), was
