Abstract

Eight molluscan species consisting of 92 specimens from six localities in the Grassy Butte area of North Dakota are here identified and located stratigraphically. The genera identified are Viviparus, Lioplacodes, Campeloma, and Reesidella. These fauna come from the Tongue River formation and the Sentinel Butte member of the Tongue River formation of upper Paleocene time.
