摘要
西瓦利克群的晚中新世出土了各种类型的麂科动物化石,这些化石或多或少都很常见。其中最罕见的是Lophochoerus nagrii,它仅见于西瓦利克组的Nagri地层(晚中新世早期)。在此之前,该物种唯一无可争议的记录来自印度西瓦利克群,采自印度喜马偕尔邦的哈里塔扬加尔。在这篇文章中,我们描述了来自巴基斯坦塔拉岗(Talagang)Nagri模式产地(Y311)的 P3-M3;这是首次报道来自锡瓦里克山脉的 L. nagrii 的上前臼齿。该物种在巴基斯坦的发现证实了其地理分布范围从印度扩展到了巴基斯坦,所报告的上部牙齿是其解剖记录中的一个新发现。
Lophochoerus nagrii (Suidae) from the Siwaliks (Neogene) of Pakistan
The Late Miocene of the Siwaliks has yielded fossils of various species of Suidae, which are more or less common. One of the rarest is Lophochoerusnagrii, found exclusively from the Nagri Formation (of early Late Miocene age) of the Siwalik Group. Previously, the only undisputed record of this species was from the Indian Siwaliks, recovered from Haritalyangar, Himachel Pradesh, India. In this article, we describe P3-M3 from the Nagri type locality (Y311) in Talagang, Pakistan; it is the first report of the upper premolars of L.nagrii from the Siwaliks. The discovery of this species from Pakistan confirms extension in its geographic range from India to Pakistan, and the reported upper dentition is an addition in its anatomical record.
