- Phylloceras sp.
- Middle Cretaceous Age (Albian Stage – 150 Million Years Old)
- Republic of Madagascar – an island country in the Indian Ocean, off the coast of Southeast Africa.
- Each half measures 3 5/16″ wide (You get BOTH halves)
This is a hand-picked example of a Phylloceras Ammonite from Madagascar. Ammonites from this location are unusually well-preserved, and are often filled with calcite crystals making it possible to cut them in half and polish them. The details of the inner chambers remained intact, and make each one a beautiful display specimen. Ammonites are an extinct group of marine invertebrate animals similar to the modern nautilus. (Cephalopoda) Like the nautilus, ammonites had a soft body with tentacles that emerged from a hollow chambered shell utilized in the manner of a submarine’s ballast tanks. Ammonites are often identified by their shell ornamentation and the structures of the wall that divide the shell’s chambers.
