摘要

本文报道了日本九州熊本县中泥盆世奈代金组的5个介形类，包括陆架近岸贝氏类和贝氏类，以及贝氏类2种。这是黑川带泥盆纪介形类化石的首次报道。分析结果表明，九州黑家川带与古赤道华南古大陆在生物地理上具有亲缘关系。

Middle Devonian ostracods from the Naidaijin Formation, Kurosegawa belt, Kyushu, Japan: Paleoecological and paleogeographical significance

This study reports five ostracod taxa from the Middle Devonian Naidaijin Formation, Kumamoto Prefecture, Kyushu, Japan comprising shelf-nearshore beyrichiid and bairdiocypridoid species, and two species of Bairdia. This is the first report of ostracod fossils from the Devonian strata in the Kurosegawa belt. Most analyzed fossils are the same species as those found in the Middle Devonian strata of Yunnan and Guangxi provinces in South China, indicating that the Kurosegawa belt of Kyushu shared biogeographical affinities with the palaeo-equatorial South China paleocontinent.

期刊介绍： Island Arc is the official journal of the Geological Society of Japan. This journal focuses on the structure, dynamics and evolution of convergent plate boundaries, including trenches, volcanic arcs, subducting plates, and both accretionary and collisional orogens in modern and ancient settings. The Journal also opens to other key geological processes and features of broad interest such as oceanic basins, mid-ocean ridges, hot spots, continental cratons, and their surfaces and roots. Papers that discuss the interaction between solid earth, atmosphere, and bodies of water are also welcome. Articles of immediate importance to other researchers, either by virtue of their new data, results or ideas are given priority publication. Island Arc publishes peer-reviewed articles and reviews. Original scientific articles, of a maximum length of 15 printed pages, are published promptly with a standard publication time from submission of 3 months. All articles are peer reviewed by at least two research experts in the field of the submitted paper.
