Abstract
Dental measurements of Pleistocene and Holocene shrews of the genus Blarina were analyzed in a multivariate assessment of evolution and paleoecology in the genus. Blarina brevicauda, or an indistinguishable precursor, apparently was the ancestral form. Two species, comparable to Holocene brevicauda and carolinensis, appeared during the Irvingtonian and were present throughout the Rancholabrean. Increasing continentality since mid-Wisconsinan time has caused further segregation of the members of the genus, with the species hylophaga appearing in the late Wisconsin. Fossils of Blarina were found in warm- moist and cool - moist faunas. The fossil record of the genus is summarized.
