Background InformationFossils - literally "having been dug up" are the preserved
remains or traces of animals, plants, and other organisms from the remote past.
Fossils are used to : 1. Reconstruct what the earth was like in the distant past 2. To show how life has changed through time 3. To correlate rock from one area to another to aid in searching
for fossil fuels and minerals.
In Ohio, fossils can be found at: Found in Fossil Park Sylvania Caesar Creek Emergency Spillway Hueston Woods State Park A few other popular Cincinnati and Dayton locations.
