Construction of Ohio Stadium was completed in 1922. At the time, it was touted as the largest poured concrete building in the world. However, some of the foundation and facing stone was limestone quarried from the Marble Cliff Quarry, along the banks of the Scioto River in Columbus. The rock was a combination of Columbus Limestone and the overlying unit, the Delaware Limestone. Both are Devonian in age (~390 million years old) and richly fossiliferous.

On Saturday, October 10, 2026, Ohio State's College of Arts & Sciences celebrated its Homecoming Tailgate Impact Showcase on the Oval before the football Buckeyes took on Maryland. The Orton Museum was there with a special interactive exhibition - "Fossils of Ohio Stadium."

Sam Walters, Johnny Kube, and Andrew Wendruff led an interactive display of an amazing set of specimens which visitors could see and touch. These are the same fossils as you can find in the walls of Ohio Stadium.
