WHITE AMMONITE FOSSIL
A White Ammonite Fossil Specimen for the collection. An amazing artifact and a natural example of the Fibonacci sequence. From the center out, the spiral increases at the ratio of Phi or the golden section, 1.618.
The name Ammonite, from which the scientific term is derived, was inspired by the spiral shape of their fossilised shells. These resemble tightly coiled rams’ horns. Pliny the Elder (d. 79 AD near Pompeii) called fossils of these animals ammonis cornua (“horns of Ammon”) because the Egyptian god Ammon (Amun) was typically depicted wearing ram’s horns. Often the name of an ammonite genus ends in ceras, which is Greek for “horn”.
