When beremendiin shrews disappeared in East Asia, or how we can estimate fossil redeposition.

The current paper first time describes a small Beremendia from the late Pleistocene deposits in the Koridornaya Cave locality (Russian Far East), which associated with the extinct Beremendia minor. The paper is the first attempt to use a comparative analytical method to evaluate a possible case of redeposition of fossil remains of this shrew. In this case, the 'comparative' part of the method corresponds to the 'faunistic approach' of Jelle Reumer, and the 'analytical' part of the method corresponds to his extended 'morphological approach. ' The analytic method uses morphospace size estimation (MSE) based on principal component analysis and estimation of the variance to evaluate redeposition of Beremendia minor from the late Pleistocene deposits in the Koridornaya Cave. This result allows us to suggest the significant environmental contribution to the East Asian beremendiin extinction, such as climatic fluctuation, landscape changes and shrew community changes between the late Pliocene and early Pleistocene. We discuss the last remains of East Asian Beremendia (Peisorex) described from the Chinese early Pleistocene localities (Chiachiashan, Haimao, Renzidong) and the last remains of Lunanosorex described from the Chinese late Pliocene localities (Qipanshan Hill and Houxushan Hill). MSE was performed for soricine tribes with the 'elongated' condylar process. [ABSTRACT FROM AUTHOR]
