Description:

East Africa, Madagascar, Jurassic to Cretaceous period, ca. 200 to 66 million years ago. A fossilized ammonite fully excavated from sediment, showcasing beautiful ammonitic suture patterns in rich hues of umber and amber. Typically hidden by the external shell wall, these intricate wavy formations are fully visible here. The fractal-like suture marks are both aesthetically striking and scientifically significant, aiding in identifying the ammonite's species and dating its period of existence. The preparer meticulously carved around the sutures at the chamber aperture to create an engaging profile, with the surface polished to a smooth, glossy finish. Size: 8" Diameter x 1.6" W (20.3 cm x 4.1 cm); 10" H (25.4 cm) on included custom stand.
