Rugged Tractor Ammonite. Featuring great markings on the outside. 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 used by nearly all religions and occults and is a big part of Sacred Geometry. This specimen is mounted on a perspex pad for enhanced display.

Ammonites are an extinct group of marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. These molluscs are more closely related to living coleoids (i.e., octopuses, squid, and cuttlefish) than they are to shelled nautiloids such as the living Nautilus species. The earliest ammonites appear during the Devonian, and the last species died out during the Cretaceous–Paleogene extinction event.
Out of all of the infinite numbers in the world, there are precious few that are given their own letter from the all-too-finite Greek alphabet. The golden ratio, also known as phi pronounced “fie”, is one of those few. An irrational number that begins 1.618…, it describes an important kind of geometrical proportion specifically, an elegant way to divide a line segment.
