among living and fossil forms, as well as the 1st appearance of flying squirrels in the fossil record, is complicated by the fact that dental features once considered diagnostic of fossil flying squirrels (e.g., those described by James [1963]) have been documented in tree and ground squirrels as well (Thorington et al. 2005).The squirrels that live in Siberia today are descendants of a later group that crossed the Bering land bridge from Alaska to colonize the area.
