Many of the animals that lived in the U.S. Midwest during the late Pleistocene are now extinct or have migrated to new areas. For example, today arctic ground squirrels are restricted to Alaska and northwestern Canada, and yet 20,000 year old remains have been found in eastern Iowa. This suggests that Iowa was once as cold as Alaska is today.
This section of the Ice Ages website provides detailed information about many of the animals that lived in the Midwest during the last period of glaciation (the Wisconsin). They are organized below by Order and Family.
