Zusammenfassung:Two fossil wing specimens from adult cockroaches (order Blattaria) were discovered during field investigations at the Cretaceous outcrop of the Cobb's Creek site (NE1/4, sec. 4, T109N, R30W; Brown County) near New Ulm, Minnesota. Prior to the present investigation, no adult fossil insect parts from Minnesota have been described from deposits as old as the Cretaceous. Lewis (1970) described immature caddisfly cases (Trichoptera) from the Cobb's Creek site.
