Forget museum displays behind glass – at Trammel Fossil Park, you become the paleontologist as you dig through ancient limestone searching for marine fossils that date back 450 million years to when Ohio was covered by a warm, shallow sea.
This unique public park offers visitors the rare opportunity to hunt for and keep genuine fossils, including brachiopods, bryozoans, and trilobites that tell the story of prehistoric life.
Located on 35 acres of preserved fossil-rich terrain in Sharonville, this former limestone quarry has been transformed into an educational outdoor laboratory where families can experience the thrill of scientific discovery.
The park represents one of the few places in Ohio where amateur fossil hunters can legally collect specimens while learning about the region’s ancient marine environment.
Fossil Hunting Adventures
Ancient Marine Life: The limestone formations at Trammel contain abundant fossils from the Ordovician Period, when Ohio lay beneath a tropical sea teeming with marine creatures. You’ll search for brachiopods (ancient shellfish), bryozoans (colonial animals), crinoids (sea lilies), and if you’re lucky, trilobites – the iconic “bugs” of the ancient seas that are prized by collectors worldwide.

Keep Exploring →Active Digging Areas: The park maintains several designated fossil hunting zones where you can split limestone rocks and search for specimens. These areas are regularly refreshed with new material, ensuring that even frequent visitors can make fresh discoveries. The limestone splits relatively easily, making fossil hunting accessible to beginners while still challenging enough for experienced collectors.
Educational Fossil Identification: Park signage and educational materials help you identify the different types of fossils you might find. You’ll learn to distinguish between various species and understand what these creatures tell us about ancient Ohio’s underwater ecosystem. The park encourages visitors to become citizen scientists, contributing to our understanding of prehistoric life.
Keep Your Discoveries: Unlike many fossil sites, Trammel Fossil Park allows visitors to keep their finds, making each discovery a permanent souvenir of your paleontological adventure. This policy transforms casual visitors into passionate fossil hunters who often return multiple times to build their collections.
Natural Setting & Trails
Quarry Landscape: The park’s unique topography reflects its industrial past as a limestone quarry, creating dramatic cliffs, exposed rock faces, and varied terrain that showcases different geological layers. These formations provide natural classrooms where you can observe how sedimentary rocks formed over millions of years.
Hiking Trails: Beyond fossil hunting, the park offers walking trails that wind through the preserved landscape, allowing you to explore the natural environment and observe how nature has reclaimed the former quarry. These trails provide excellent opportunities for photography and wildlife observation.

Spring wildflowers are particularly spectacular, carpeting areas with colorful blooms that contrast beautifully with the gray limestone.
Seasonal Wetlands: Temporary pools and wetland areas within the park support amphibians, birds, and other wildlife, adding another dimension to your visit. These ecosystems demonstrate how natural processes continue to shape the landscape even after human intervention.
Visitor Experience & Preparation
Free Access: The park is completely free to visit, making it an exceptional value for families seeking educational outdoor recreation. This accessibility ensures that economic barriers don’t prevent anyone from experiencing the excitement of fossil discovery.
Bring Your Own Tools: Successful fossil hunting requires basic tools – bring a hammer, chisel, safety glasses, and sturdy gloves. A small shovel and collecting bags are also helpful. The park doesn’t provide tools, so come prepared with your own equipment for the best experience.
Weather-Dependent Activity: Fossil hunting is weather-dependent, with dry conditions being ideal for splitting rocks and searching for specimens. Wet weather can make the limestone slippery and harder to work with, so plan your visit accordingly.
