The remains of large porcupines (an incomplete skull, cranial and mandibular fragments, isolated teeth and postcranial bones) from the Early Pleistocene Taurida cave locality in central Crimea (Belogorsk district, Zuya village) are referred to the species Hystrix (Hystrix) refossa Gervais, 1852, which has not been reported from Crimea previously. Based on the stages of eruption, replacement and attrition of the lower dentition, the presence of individuals of six age categories, from juvenile to senile, was established. One dentary shows an intravital loss of cheek teeth, presumably caused by abnormal development of their roots and sockets. [ABSTRACT FROM AUTHOR]

The lower jaw and dental remains of the brush-tailed porcupine are described from the Pleistocene–Holocene boundary deposits of the Bud cave in northern Vietnam. In terms of the average length of the cheek teeth, this porcupine is somewhat larger than the modern Atherurus macrourus (Linnaeus, 1758), but slightly smaller than the Pleistocene A. karnuliensis Lydekker, 1886; relatively small incisors make it possible to assign the form from the Bud сave to A. macrourus. The finding is the first fossil record of this species in Vietnam. [ABSTRACT FROM AUTHOR]

The dental remains of the porcupine from the Pleistocene deposits of the Lang Trang cave in northern Vietnam are described. Previously, this porcupine was identified as Hystrix brachyura Linnaeus, 1758 or H. indica Kerr, 1792. Based on the analysis of morphometric data, the systematic position of the form from Lang Trang and other large Pleistocene porcupines of Vietnam is determined as Hystrixkiangsenensis Wang, 1931.
