The Cincinnati Ohio area is famous for its fossils. Though they have been collected extensively and samples can be found in museums around the world, anyone walking near a stream or a low area or along the edge of a road or highway can find rocks full of fossils. This image was taken at the Nature Center which is near the Little Miami River : Designated “National Scenic River”. The banks of the river and it’s streams are covered with innumberable rocks and most of them contain fossils.
Here is a small quote from a local piece on the formation of these fossils.
“The fossils found near Cincinnati and Southeastern Indiana are world renowned for their abundance and state of preservation. This was made possible by the conditions that existed in the area. In the Cincinnati area, shallow seas and life dominated the environment. To the East, active volcanic mountain highlands were being constantly eroded by the forces of nature. As the erosion progressed, the sediment was carried downlope into the shallow Sauk Sea to the West. This sediment buried many organisms under an airtight, muddy blanket which encouraged the remarkable preservation seen in the fossils that were left behind. The muddy blanket eventually turned into limestone which is found extensively in Indiana, Kentucky, and Ohio. "
This period is called ’The Ordovician Period and existed from 490-445 million years ago.
School children love going on trips to hunt fossils and some of them have grown up to be become experts in the field.
We take these treasures for granted around here but visitors are often amazed at the formations and their abundance.
