Abstract：
Porcupines, members of the Hystricidae family, represent a unique group of herbivorous mammals. This study details the identification of a newly discovered mandible fragment of Hystrix primigenia, along with a right cheek tooth series from the middle Turolian Kemiklitepe-A fossil locality. While Hystrix fossils are found in numerous localities, the materials are often limited to a few dental fragments or isolated teeth, posing challenges to systematic investigations. The examination of this lower tooth series prompted a comprehensive review of all H. primigenia findings across Eurasia, shedding light on its adaptive characteristics over time and space. Our paleobiogeographical analysis indicates the absence of H. depereti in Late Miocene Türkiye, while the dispersal range of H. primigenia is broader than that of H. depereti in Eurasia. Additionally, the study delves into the discussion of H. primigenia and H. depereti findings in Eurasia, ultimately refining the categorization of Late Miocene Hystrix discoveries in Türkiye to two species: H. primigenia and H. kayae. Our review suggests the possibility of an additional H. kayae finding from Samos, Greece.
摘要：
豪猪,细胞器科的成员,代表一组独特的食草哺乳动物。这项研究详细介绍了新发现的Hystrixprimigenia下颌骨碎片的鉴定，以及来自TurolianKemiklitepe-A化石地点的右脸颊牙齿系列。虽然在许多地方都发现了Hystrix化石，这些材料通常仅限于一些牙齿碎片或孤立的牙齿，对系统调查构成挑战。对该下牙齿系列的检查促使对整个欧亚大陆的所有H.primigenia发现进行了全面审查，揭示其随时间和空间变化的自适应特性。我们的古生物地理分析表明，在上世纪晚期蒂尔基耶，没有H.depereti。而在欧亚大陆，H.primigenia的散布范围比H.depereti的散布范围更广。此外,这项研究深入研究了欧亚大陆对H.primigenia和H.Depereti发现的讨论，最终将在Türkiye发现的上新世Hystrix的分类细化为两个物种：H.primigenia和H.kayae。我们的审查表明，从Samos发现额外的H.kayae的可能性，希腊。
