Description from the seller
Large pair of Cleoniceras ammonites from Madagascar – 19 cm – polished and mineralized fossil
Description
Stunning pair of fossil ammonites from Madagascar, cut along the axis and carefully polished to reveal the remarkable internal structure of the fossil.
The two halves display a beautiful symmetry when joined, allowing appreciation of the complete spiral and the many natural suture lines, particularly well defined.
The ammonite chambers are partially filled with natural crystalline mineralization, offering striking contrasts among anthracite gray, silvery gray, white, and black. Some cavities feature a particularly aesthetic crystalline texture.
The fossil is presented in two complementary halves, each measuring about 19 cm in diameter and 2 cm thick.
