If you ever visit the Speed Art Museum in downtown Louisville next to the campus of the University of Louisville, check out the polished columns leading the Grand Staircase. The arrow in the image points to an area of the column with interesting fossils. It is next to the entrance to the Ancient art rooms.
On a future visit, I might ask the staff if they have any information about where rock columns were quarried at.
Also in the first picture you can see (in between column and statue) in the distance an Egyptian sarcophagus lid made of limestone. It has quite a few fossils embedded in it. Unfortunately, it is on loan from another museum and is not allowed to be photographed so I cannot make a specific post about it. :( So if you visit the museum check it out up close in its display case and see if you can find the fossils!
