Abstract

A crevice cave in the Niagara Escarpment southwest of Milton, Ontario, has yielded remains of the painted turtle (Chrysemys picta), short-tailed shrew (Blarina brevicauda), smoky shrew (Sorex fumeus) big brown bat (Eptesicus fuscus), long-eared bat (Myotis keenii), little brown bat (M. lucifugus), red-backed vole (Clethrionomys gapperi), meadow vole (Microtus pennsylvanicus), red squirrel (Tamiasciurus hudsonius), deer mouse (Peromyscus maniculatus), muskrat (Ondatra zibethicus), and wapiti (Cervus canadensis). Because wapiti have been absent from the area since 1750 AD, a minimum age of 215 years is suggested for the fauna.
