Description
An exceptionally polished and sliced fossil ammonite of the genus Cleoniceras, showcasing the stunning internal chamber structure and suture patterns typical of this extinct cephalopod. This genuine Aptian-aged specimen dates back to the Early Cretaceous period and was unearthed from the fossil-rich sedimentary deposits of Madagascar.
Cleoniceras is a member of the Ammonitida order, known for its planispiral, tightly coiled shell and intricate suture lines. When sliced and polished, these fossils reveal captivating mineral infillings, usually calcite and aragonite, which form over millions of years within the chambered shell. These features make Cleoniceras fossils highly sought after by collectors and interior decorators alike.
