摘要

摘要:在冲绳岛Nakijin村Gogayama山地表的早更新世沉积物中,发现了大量蛇椎骨化石,以及许多其他脊椎动物化石。这是整个琉球群岛最古老的蛇化石记录。根据我们之前对日本和邻近地区现存蛇的研究所阐明的诊断特征,我们将这些化石蛇椎骨鉴定为最低的分类类别。结果,至少有4个属的椎骨被识别出来,分别是蛭科的cyclophiops和Dinodon,蝰蛇科的Protobothrops(以前的Trimeresurus)和elapidae科的Sinomicrurus。其中,经鉴定属于恐龙属的椎骨进一步分为两种不同的形式,尽管两者都类似于D. rufozonatum,这是一种现存的物种,目前在冲绳岛或琉球中部任何周围的小岛上都没有出现。被鉴定为属于另外三个属的椎骨与目前发生在冲绳岛的三个现存物种的椎骨大体相似,但略有不同。

Early Pleistocene Fossil Snakes (Reptilia: Squamata) from Okinawajima Island in the Ryukyu Archipelago, Southwestern Japan
Abstract A number of fossil snake vertebrae were collected from Early Pleistocene deposits exposed on a hill surface at Gogayama, Nakijin village, Okinawajima Island, along with many other vertebrate fossils. These represent the oldest fossil records of snakes for the whole Ryukyu Archipelago. We identified each of these fossil snake vertebrae to the lowest taxonomic category possible based on diagnostic features elucidated in our previous study of extant snakes from Japan and adjacent regions. As a result, the vertebrae of at least four genera—Cyclophiops and Dinodon of the family Colubridae, Protobothrops (formerly Trimeresurus) of the family Viperidae, and Sinomicrurus of the family Elapidae—were recognized. Of these, vertebrae identified as belonging to the genus Dinodon were further divided into two distinct forms, although both resembled D. rufozonatum, an extant species that does not presently occur in Okinawajima or any of the surrounding islets in the central Ryukyus. Vertebrae identified as belonging to the other three genera were largely similar to those of the three extant species currently occurring in Okinawajima but with slight differences.
