Description

This was at Mima Mounds prairie just a bit north of the interpretive center and in the middle of my study plot. I think it's a vole or a mole. The skeleton was complete.

Definitely not a mole, since they have a crocodile-like arrangement instead of the diastema and big front incisors of Rodentia. I agree it's a vole based on what I can make out of the surface of the upper molars, the large auditory bullae & meatus, and the sort of right angle formed by the jutting lower molars. According to my guide possible voles in range are:
Microtus richardsoni, M. oregoni, M. longicaudus, M. townsendii, and Clethrionomys gapperi; most of which have different habitats, so you could possibly narrow it down a bit based on that.
