Yellow Ammonite Fossils

In the previous post, I wrote about a visit to Sant Ignazio Roman Catholic Cathedral in Rome, Italy. I found some ammonite fossils in the floor slabs. The last post was about the red fossils, this one is about the yellow ones. I believe this yellow stone is referred to as Ammonitico Giallo. Fossils from this layer are from the Jurassic Period.

Under the crest is some text embedded in the stone, it looks like roman numerals MDCCXLVII which convert to 1747 in decimal. If that is the year of installation then 272 years ago as of this writing.

On the Internet is a waymarking web site that documented this find. They are similar to the ones I found at St. Peter's Basilica in Rome.

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.

UPDATE (2022): These ammonoids could date to the Upper Jurassic Period of the Rosso Ammonitico Formation, Oxfordian Stage, Verona Province, Venetia Region of Italy. This iron enriched (red) limestone is also known as Red Verona Marble or Rosso Verona Marble.

Elephas antiquus Tooth Fossil at Roma Italy

Here is a picture of an elephant tooth fossil housed in a display case at the Geologia building located on the campus of Sapienza University of Rome. The case can be found on the second floor of the building. The fossil is called Elephas antiquus and lived during the Pleistocene. The paleontology museum is on the 3rd floor of this building and houses a full skeleton of this ancient animal.

The university was founded in 1303 by Pope Boniface VIII. In 1870, it became a public university for the state of Italy.
