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.

BACKGROUND: A newly discovered zoonotic infection carried by ixodid ticks, Anaplasma capra, affects a wide variety of hosts, including numerous mammals. A. capra most likely infects erythrocytes or endothelial cells in mammals. This study aimed to investigate the A. capra pathogen in goats in Türkiye\'s Van province.
METHODS: A total of 200 goat blood samples were examined. Goat samples were subjected to partial amplification of the gltA gene fragment using a nested polymerase chain reaction.
RESULTS: A. capra DNA was detected in 0.5% of goat blood samples. Phylogenetic analysis of a partial gltA gene fragment showed that the Eastern Türkiye isolate, closely grouped with A. capra isolates reported from wild and domestic ruminants in France, Türkiye, and Kyrgyzstan, formed a distinct clade.
CONCLUSIONS: This is the first report of A. capra in goats in Van province, Eastern Türkiye.
