A large solid Ammonite Acanthopleuroceras maugenesti fossil. This is a natural fossil specimen. An amazing artifact and a natural example of the Fibonacci sequence. Also from the center out, the spiral increases at the ratio of Phi or the golden section, 1.618. The distance of the planets from the Sun average the Phi Ratio. This number is also related to Pi and the Fibonacci Sequence. This Phi Ratio is part of Sacred Geometry.
