4" Tall Composite Ammonite Fossil Display - Madagascar
This striking cluster of 110-million-year-old ammonite fossils comes from the Mahajanga Province of Madagascar. The piece measures 4" tall by 3.4" wide, and the base has been cut flat so it displays beautifully on any level surface. The ammonites are primarily of the genus Cleoniceras. Some specimens have been cut and polished to reveal their intricate internal structure, while others have been left whole and polished to a glossy finish.
This is a composite piece, meaning the ammonite fossils themselves are genuine, but they have been artistically mounted onto the rock matrix to create this eye-catching display.

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.
