4.6" Polished Ammonite (Puzosia) Fossil - Madagascar
This is a 4.6" wide polished ammonite from Madagascar of the genus Puzosia. It is absolutely gorgeous, with portions of the specimen displaying the distinctive "oak-leaf" suture pattern along the polished surface. This 110 million year old ammonite is truly a natural work of art and is very displayable on the included acrylic stand. The sutures on it have been meticulously exposed and cleaned making the ammonite look that much nicer.
About Ammonites
Ammonites were predatory, marine mollusks that thrived during the Paleozoic and Mesozoic eras, particularly in the Jurassic and Cretaceous periods, before going extinct around 66 million years ago. These creatures are characterized by their coiled, spiral shells, which resemble the modern-day nautilus. Ammonite shells were divided into chambers; as they grew, they built new chambers and sealed off the old ones. These chambers were filled with gas, which helped them control buoyancy in the ocean.
The outer shell of ammonites often displays intricate ribbed or ridged patterns and their fossils sometimes show a wide range of beautiful colors due to mineralization over time. The shells fossilized well, making ammonites abundant in the fossil record.. In addition to being popular in fossil collections, ammonites are valuable in geological studies, as they serve as index fossils, helping scientists date rock layers and understand the Earth's prehistoric environments.
