Fossils in picture are Ancyloceras heteromorph ammonite fossils. They date to the Cretaceous Period (115 million years ago) and were found in Morocco. The fossils were on display at a northern Indiana USA museum.
The museum is called Joshua Tree Earth and Space Museum and is located at 106. S. Michigan Street, Lakeville, Indiana. Admission is free but they could use the donations. They are open 10 AM to 6 PM daily and can be reached at 574-784-2291.
