Ammonite Disc, Beautiful Display Disc, Fossil Ammonite, Cephalopods, Spiral-Shaped Shells, 110mm, 4.4" Diameter

These are beautiful ammonite display disc‘. Suitable for any fossil lover. They are made up of small polished ammonite halves in resin. They are 4.4" or 110mm diameter with a high polish surface. The earliest traces of Ammonite date back to 420 million years ago, while the last known traces fall to 60 million years ago.
Ammonite fossils, remnants of ancient marine creatures, are widely recognized for their spiral-shaped shells and are associated with various symbolic meanings, including rebirth, transformation, and ancient wisdom. They are also linked to life‘s evolution, spiritual growth, and the clearing of negative energies.
Madagascar is well-known for producing beautifully preserved ammonite fossils, particularly from the Jurassic and Cretaceous periods. These fossils are often sought after for their aesthetic appeal when cut and polished, revealing inner chambers filled with crystals and other minerals. The ammonites from Madagascar are significant for both scientific study and as decorative pieces. The cut and polished ammonites from Madagascar are highly prized for their aesthetic qualities, making them popular display items.
They lived from the mid Paleozoic era through the entire Mesozoic finally going extinct with the dinosaurs at the end of the Cretaceous Period. Madagascar produces some of the most beautiful ammonite fossils in the world with chambers filled with agate or sometimes empty and lined with crystals!"
Ammonite fossils are the remains of marine cephalopods (related to octopuses and squid) that lived millions of years ago. These creatures had distinctive coiled, chambered shells, and their fossils are valuable for understanding past marine environments and for dating rock layers. They are found on multiple continents and are a popular item for fossil collectors.
Ammonites were a diverse group of marine invertebrates with external, spiral-shaped shells. They are not related to snails, but rather to modern-day cephalopods like octopuses, squid, and nautilus.
Their shells, which were made up of gas-filled chambers, fossilized readily, making them common in the fossil record.
Ammonites are important as index fossils. This means they are used to determine the relative age of rock layers because they evolved and spread rapidly, and their fossils are found in many different locations.
Most ammonites went extinct along with the non-avian dinosaurs at the end of the Cretaceous period, approximately 66 million years ago, due to a mass extinction event.
Ammonite fossils come in a wide variety of shapes and sizes, with intricate suture patterns (the lines where the internal shell walls meet the outer shell).
Ammonite fossils are found worldwide, with particularly rich deposits in areas that were once ancient seafloors.
In some locations, like Alberta, Canada, the mineralized shell of ammonites can form a gemstone called ammolite, known for its vibrant iridescent colors.
