This mineral deposit (thought it was fossil) is in the support of the Illinois Central 14th Street Railroad Bridge in Clarksville, Indiana near the Falls of the Ohio State Park.
This the last picture I took at the bridge and it looks like some sort of coral. It has this neat white residue that looks like salt or something on it. I am guessing it is been weathering since the bridge was built in 1868 so its been exposed for a long time.
After consulting the naturalist as the nearby Falls of the Ohio State Park he told me it was calcium carbonate (travertine).

Fossil in Bridge Support
This fossil is in the support of the Illinois Central 14th Street Railroad Bridge in Clarksville, Indiana near the Falls of the Ohio State Park.
I find this fossil most interesting because I am not sure what it is but it looks like a crinoid stem on its side and the brown looking arms look like part of its calyx. Maybe it is a squished coral or sponge.

Interesting Desposit on Part of Bridge
If you visit Falls of the Ohio State Park more than likely you will go under the Illinois Central 14th Street Railroad Bridge connecting Clarksville, Indiana and Louisville, Kentucky. The bridge was built in 1868 and crosses the Ohio River.
Some of the stones that support the bridge have fossils or mineral desposits in them and here is one I took a picture of. Unfortunately, I had the camera set for tungsten lighting while in bright sunlight so it made the image turn blue. I think this is some sort of coral but it has a white snow look to it like it is covered in salt.
I thought this was a coral fossil but after consulting the naturalist as that Falls of the Ohio State Park he told me it was calcium carbonate (travertine).
The bridge is also known as the Pennsylvania Railroad Bridge or Conrail Railroad Bridge.

Unidentified Ordovician Horn Coral
Here is a small horn coral found in the Jeffersontown Kentucky area. The Kentucky Geological Survey classifies this area as Ordovician in the Drake Formation.
I used Photoshop to count the number of septa to 55.
