Local schools, museums, and rock clubs often have detailed directions to fossil-rich locations. This region of the country is one of the best fossil-collecting sites in the world. The best fossils in the Upper Midwest are no doubt those of the Ordovician found in the Cincinnati region, which encompasses large parts of northern Kentucky, southeastern Indiana and southwestern Ohio. The gray limestones and claystones exposed on hillsides, creekbeds and roadcuts are intensely fossiliferous. Professional paleontologists have been studying these rocks and fossils for more than 200 years.
International paleontologists visit the area often to collect from the abundant fossils.
Fossils of many kinds are a rich natural resource throughout the United States. They remind us of our long and glorious natural heritage.
