Kemiklitepe is a well-known locality with four recognised fossiliferous horizons, KTA to KTD, which have yielded a plethora of mammalian remains. Previous taxonomic studies indicate the presence of three giraffid taxa: Samotherium major and Palaeotragus rouenii from the uppermost three horizons, KTA, KTB and KTC, as well as Palaeotragus rouenii and Samotherium? sp. from the lowermost KTD horizon. In this study a new locality, Kemiklitepe-E, is presented for the first time. Kemiklitepe-E is located approximately 350 m NW of the classic Kemiklitepe locality. The fossiliferous sedimentary rocks at Kemiklitepe-E occur at the same stratigraphic level as localities KTA, KTB and KTC. The preliminary faunal list includes representatives of Proboscidea, Chalicotheriidae, Equidae, Bovidae and Giraffidae. Comprehensive descriptions and comparisons of the Kemiklitepe-E Giraffidae specimens suggest the co-occurrence of two large giraffids: Samotherium major and Helladotherium duvernoyi. Samotherium major, previously documented from this region, is the most common taxon at Kemiklitepe. Helladotherium duvernoyi is rare at Kemiklitepe and here reported for the first time. The two taxa coexisted during the middle Turolian in Greece and Western Anatolia. In addition, it is suggested that specimens of Samotherium? sp described from KTD possibly belong to Samotherium neumayri. Based on the stratigraphic position of fossiliferous rocks, as well as the faunal data presented herein, the newly discovered locality is considered to be of middle Turolian (MN12) age.

来自新中新世晚期 Kemiklitepe-E 化石产区(土耳其西部安纳托利亚)的大型长颈鹿(哺乳动物,反刍动物)

Kemiklitepe 是一个著名的地方,有四个公认的化石层位,从 KTA 到 KTD,已经产生了大量的哺乳动物遗骸。以前的分类学研究表明存在三个长颈鹿类群:来自最上层三个视野的Samotherium majorPalaeotragus rouenii,KTA、KTB 和 KTC,以及Palaeotragus roueniiSamotherium? sp。从最低的 KTD 地平线。在这项研究中,首次展示了一个新的地点 Kemiklitepe-E。Kemiklitepe-E 位于经典 Kemiklitepe 地区西北约 350 m 处。Kemiklitepe-E 的化石沉积岩与 KTA、KTB 和 KTC 位于同一地层。初步的动物群名单包括长鼻科、Chalicotheriidae、马科、牛科和长颈鹿科的代表。对 Kemiklitepe-E 长颈鹿科标本的全面描述和比较表明两种大型长颈鹿同时存在:Samotherium majorHelladotherium duvernoyiSamotherium major以前记录在该地区,是 Kemiklitepe 最常见的分类单元。杜维诺伊海德拉草在 Kemiklitepe 很少见,这里是第一次报道。这两个分类群在希腊和安纳托利亚西部的图罗利安中期共存。此外,建议Samotherium的标本?从 KTD 描述的 sp 可能属于Samotherium neumayri。根据化石岩石的地层位置,以及这里提供的动物群数据,新发现的地点被认为是中图罗利安(MN12)时代。
