Ammonite Fossils in St. Ignazio Church - Rome


Recently while visiting Sant Ignazio Roman Catholic Cathedral in Rome, Italy I found some ammonite fossils in the floor slabs. After researching on the Internet, there is a waymarking web site that documented this find. They are similar to the ones I found at St. Peter's Basilica in Rome.



The ammonite fossils are embedded in a number of red and yellow polished limestone slabs in the floor. The slabs are in the main floor of the church, the left side section of church with a statue, and the yellow stone on a crest toward the center floor of the church. They appear to be Rosso Ammonitico Lombardo (red polished limestone). This stone is dated to the Jurassic Period. I am not sure about the yellow stone, it might be Ammonitico Giallo. I hope to have a post about this in the near future.
