Systematic study of the Quaternary insectivores in the Japanese Islands.

在日本列岛，食虫动物的遗骸是从中更新世至全新世的洞穴和裂缝沉积物以及新石器时代遗址中发现的。通过对这些化石的分类学分析以及对含化石沉积物的地层学研究，揭示了第四纪晚期食虫动物群的演替。中更新世中期的动物群以大量出现已灭绝的鼠鼩（Anourosorex）和现存的鼠鼩（Urotrichus talpoides）为特征。它还包含已灭绝的Blarinine 鼩（Shikamainosorex densicingulata）和刺猬（Erinaceus sp.）。中更新世晚期的动物群与前一时期的动物群基本相同，只是少了一些次要成分。在晚更新世晚期，已灭绝的鼠鼩数量减少，在晚更新世早期和晚期之间，已灭绝的鼠鼩数量减少。全新世动物群以鼩鼹鼠和鼹鼠（Mogera spp.）为主，但没有灭绝的物种

In the Japanese Islands, insectivore remains are recovered from cave and fissure sediments of Middle Pleistocene to Holocene age, and from Neolithic sites. Taxonomic analyses of the remains as well as stratigraphic studies of fossil-bearing sediments reveal the insectivore faunal succession during the later part of the Quaternary. The fauna of the middle Middle Pleistocene was characterized by the abundant occurrence of extinct mole-shrew (Anourosorex japonicus) and extant shrew-mole (Urotrichus talpoides). It also contained extinct blarinine shrew (Shikamainosorex densicingulata) and a hedgehog (Erinaceus sp.). The late Middle Pleistocene fauna was essentially identical with that of the preceding time except for the absence of a few minor elements. In the Late Pleistocene, the extinct mole-shrew decreased in number, and the blarinine shrew became extinct between the early and late Late Pleistocene. The Holocene fauna was dominated by the shrew-mole and moles (Mogera spp.), but contained no extinct forms.
