Geocache Description:

Trammel Fossil Park is a fossil dig park open to the public in Sharonville, Ohio. Fossils found here are from the Ordovician period of the Paleozoic era.

The Ordovician Period occurred XXX million years ago and Trammel Fossil Park represents Y million of those years. The rocks found here contain some of the oldest forms of invertebrate animals lacking a backbone. There were no amphibians, reptiles, dinosaurs, mammals, and most certainly no humans.


Four million years ago when shallow seas covered North America the bedrock underlying Cincinnati and the Tristate region was formed at this time with primitive forms of algae advancing to the edges of the land. Geologist have called this time the late Ordovician period. The entire state of Ohio was lying 20 degrees south of the equator in the warm shallow sea, similar to the Bahamas at this time. During certain times the western edge of Ohio was emerging as muddy islands with limy sediments being very dominant. Volcanic activity and mountain building to the eastern side of Ohio produced periodic layers of ash over the entire state and muddy deltaic sediments in eastern Ohio. The seas deepened in later Ordovocian time, covering the entire state. Primitive fish swam in part of this sea but not in the Cincinnati area. At the close of the Ordovocian time, continental glaciation in the southern hemisphere lowered sea levels and produce this fossil dig. In fact, the layers of limestone and shale composing the bedrock serve as a scientific standard for comparison throughout North America and are called the “Cincinnatian Series.”


Trammel Fossil Park is named after the family who donated the 10 acres to the City of Sharonville, the R.L. Trammel Family. When this land was donated to the City of Sharonville, it developed it into a place where schools and avid fossil hunters could come and explore. Since the park has recently been opened to the public, there are many fossils in very good condition for everyone to take home a souvenir. Schools as far as New York have come to Trammel Fossil Park for exploration. The cordinated listed are to the entrance of the park. Please take a picture of yourself by the sign with the park name and your GPS or take a picture of the park sign with your GPS clearly showing the cordinates. Enjoy!!!
