| Research Abstract |
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.
