The Logan Formation (Mississippian, Osagean) is a siliciclastic unit exposed throughout central Ohio. It has not been extensively studied within the past twenty-five years; the most recent study was an Independent Study project performed in 1983. The present study focuses on samples collected from an outcrop near the College of Wooster. These samples were analyzed and compared to the paleoenvironments and paleocommunities described in previous studies. The Logan Formation was most likely part of a proximal prodelta, being comprised mostly of fine sandstones with some shales and conglomeratic layers. This study assemblage was a shallow marine filter feeding community dominated by Aviculopecten and Syringothyris. Other filter feeders include bivalves, crinoids, and bryozoans. A few nektic carnivores, Mooreoceras and Kazakhstania, preyed on this community, and herbivorous and coprophagous gastropods were also present.
