Palynologic samples for this study were collected in April of 1975 at the Hawthorne and Minnehaha Mines near Linton and Dugger, Indiana, respectively. All samples were taken from the Coal No. 7 and the overlying shale.A total of eighty-three species assigned to thirty-one genera were recovered. Sixty-six species assigned to twenty-nine genera were recovered from the Hawthorne Mine and forty-seven species assigned to twenty-three genera were recovered from the Minnehaha Mine. Comparison of the palynomorph floras of the two localities reveals twenty-one genera and thirty-three species in common to both mines.Palynologic data from the sample area reveals two slightly different depositional basins. The ecology of the area was probably a coastal-swamp type of environment with an abundance of arborescent lepidodendrids.Ball State UniversityMuncie, IN 47306
