The present paper is a survey of Pleistocene mammoth and mastodon remains from western Iowa. Included are locality data and references to the literature for over 350 specimens from 32 of 41 counties surveyed. Mammoths are found to be more numerous than mastodons, reversing the pattern observed in the woodland areas adjoining the present-day Prairie Peninsula. The first radiocarbon date for the mastodon in Iowa (13,520± 135 B.P.) is reported from Harrison County. None of the localities surveyed have provided any evidence of early man.
