Abstract

The muskrat (Ondatra spp.), a common element in late Kansan and post-Kansan deposits, provides a valuable Stratigraphic tool for deposits of glacial age, in terms of the chronocline proposed by Semken (1966). However, specimens of interglacial age commonly appear out of sequence in the regression. In addition, the nearly ubiquitous distribution in North America of modern muskrats has precluded paleoecological interpretations other than for the presence of permanent water.
