摘要

摘要在韩国东南海岸附近的浦项市中新世中期杜荷组(延日群)中，发现了密集的关节型蛇类。这些标本在这里被描述为一个新种，即浦项蛇，它与同类的不同之处在于具有长而细长的口腔乳头和微小的四边形臂梳状乳头。这一新物种构成了朝鲜化石记录中第一个被确定的蛇总纲的例子。新种的聚集密度与日本化石和现存蛇尾虫的聚集密度相似。

A New Species of Ophiura (Echinodermata, Ophiuroidea) from Miocene Deep-Sea Deposits in the Pohang Basin, Korea

Abstract. Dense aggregations of articulated ophiuroids, in external mould preservation, were discovered in the middle Miocene Duho Formation (Yeonil Group) of Pohang City, near the southeast coast of Korea. These specimens are here described as a new species, Ophiura pohangensis, which differs from congeners in having long, slender oral papillae, and tiny quadrangular arm comb papillae. The new species constitutes the first well-identified example of the class Ophiuroidea in the fossil record of Korea. Aggregation density of the new species is similar to that of occurrences of both fossil and extant Ophiura sarsii sarsii across Japan.

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).
