Fossil Park (Sylvania) is a premier fossil collecting location in Lucas County, Ohio. The site exposes Middle Devonian fossils where visitors can hunt for trilobites, brachiopods, corals, crinoids, and bryozoans.
The site is an approximately 5-acre accessible dig area operated by Olander Park System. Fossil-bearing shale is trucked in regularly from nearby Hanson Aggregate quarries. The park contains over 200 species of Middle Devonian fossils. It is open mid-April through October on weekends and select weekdays. There is free admission and parking. Tools are prohibited as the shale is soft enough to break by hand. Water stations and covered work areas with benches are provided, and restrooms are available. The site was named one of two premier Devonian fossil sites in the world. Educational field trip programs are also available.
The site was formerly operated as a cement quarry by various companies including Medusa Portland Cement Company. Property was acquired by Hanson Aggregates Inc. in 1995. In 1999, Olander Park System, Hanson Aggregates, and Sylvania Township developed a proposal to create a public fossil park. The park officially opened in 2001 and has received state and national reclamation awards.

What Fossils You’ll Find
Fossil Park contains Middle Devonian fossils preserved in limestone and shale.
Trilobites are the primary fossil assemblage at the site. Brachiopods are also found throughout the collecting area. Corals occur less frequently but have been been discovered at Fossil Park.
Geologic History
Fossil Park exposes the Silica Formation, a significant Middle Devonian geological unit in Lucas County, Ohio.
Millions of years ago, the area that is now Sylvania, Ohio was covered by shallow tropical seas. The climate was warm and tropical with shallow marine environments. Northwest Ohio was near the equator during the Middle Devonian.
As these ancient organisms died, sediments buried and preserved their remains. Over millions of years, geological processes transformed these sediments into the fossil-bearing rocks visible at Fossil Park today.
How Fossil Park Became a Fossil Collecting Site
Fossil Park originally operated as an industrial site where commercial activities exposed fossil-bearing rock layers. Quarrying, mining, or excavation operations removed overlying sediments and revealed ancient deposits that had been buried for millions of years.
After industrial operations ceased, Fossil Park transitioned to a location where fossil enthusiasts could legally collect specimens. The legacy of this industrial activity created the accessible rock exposures that make fossil collecting possible today. Many of the world’s most productive fossil sites share this history of industrial operations inadvertently revealing paleontological treasures.
