Neotoma floridana Ord 1818—Eastern WoodratRegional Pleistocene distribution of Neotoma floridana.

Modern distribution of Neotoma floridanaCurrently, N. floridana occurs mostly to the east of our region, though an arm reaches west into east-central Colorado (Fig. 1). Wiley (1980) noted that although most of its range is in eastern deciduous forest, it also extends into the Great Plains and, in eastern Colorado, lives with scanty rainfall and vegetation. Wiley also noted that this species is different from all other species that have adjacent ranges in having the anterior palatal spine forked (Fig. 2).
