Ammonitic - lobes and saddles

Ammonites are an extinct subclass of the Ammonoidea and excellent index fossils. Their closest living relatives are in all probability the Coleoidea (octopus, squid, and cuttlefish).
Ammonites' shells have mostly the form of flat spirals but there are also heteromorphs. Their soft body parts are practically never received in any detail.
These products are beautiful and rare.
 

• Long ago, when dinosaurs roamed the Earth, Ammonites swam in the oceans.
• Ammonites were creative creations of nature, with spiral shells similar to those of today's snails.
• They were very successful creatures and lived on Earth for about 400 million years.
• Unfortunately, Ammonites went extinct about 65 million years ago, along with the dinosaurs.
• However, their shells have been preserved forever and are sometimes found as fossils.
• These fossils are now very rare and valuable to scientists and collectors.
• The fossil we will see today comes from Madagascar and is several million years old.
• It has an impressive size of almost half a meter and is very well-preserved.
• When examining the shell closely, you can see the spiral structure and fine lines that indicate the Ammonite's life in the ocean.
• It is fascinating to think that this shell was worn by a living creature millions of years ago and can still tell us so much about the history of the Earth.
