Wildlife ID materials

["Kathleen S. Hass"]

We are currently in need of a book on identification of skulls of
wildlife in the Great Lakes region or North America.  After searching
many sources we have been unable to find a title written at a level that
is accessible to middle school students.  Our science staff would like us
to purchase such a book for our media center.  If you know of any titles,
(print or electronic media), please reply. Thanks!
