Whole and polished Cleoniceras ammonites. In some specimens iridescent flashes can be observed.
Its collective name refers to its resemblance to the spiral horns of a ram, with which the Egyptian god Amun was depicted in his Roman adaptation (Jupiter-Amun).
The Ammonites were a group of cephalopods with a spiral shell, which thrived in the Mesozoic oceans, and abruptly went extinct along with the dinosaurs.
The group, numbering some 10,000 species, disappeared 65 million years ago, providing uncompromising support for biological evolution and evidence for our planet's changing biodiversity.
