About Ammonites:
Ammonites were extinct marine molluscs that thrived for over 300 million years, from the Devonian Period until their extinction at the end of the Cretaceous. While their coiled shells resemble those of modern snails, ammonites are actually more closely related to modern-day squid, octopuses, and cuttlefish (coleoids), not gastropods.
These ancient cephalopods had a coiled, chambered shell, which they used for buoyancy control, similar to the modern nautilus. The intricate internal chambers are often filled with calcite crystals and mineral deposits, which, when polished, reveal spectacular natural patterns—a true testament to nature’s beauty.
About This Specimen:
This ammonite fossil has been expertly sliced in half and polished, showcasing the unique internal chamber structures and vibrant coloration caused by mineralisation over millions of years. The result is a captivating display piece with incredible aesthetic appeal and scientific value.
Each chamber once held gas or liquid, allowing the ammonite to move vertically in the water. The polished surface highlights these details beautifully—often revealing amber, honey, brown, and even iridescent hues, depending on the mineral content and preservation.
