60 – 500 million years old, ammonites are an extinct form of mollusk related to the octopus and chambered nautilus. Like the nautilus, it had a hard shell with a distinctive spiral pattern. Ammonites range in size from 1 mm to over 2 feet, and vary in the type of mineral replacement during fossilization. The name comes from its resemblance to a ram’s horn: in Egyptian mythology, the God Ammon looked like a man with horns like a ram. Ammonites are found in Canada, Europe, Madagascar, Peru, and Morocco.
Also known as “Fools Gold,” this widely distributed iron sulfide mineral has fooled many miners into thinking they’ve struck it rich. Pyrite is a valuable sulfur ore used to make sulfuric acid and iron sulfates. In Greek, pyrite means “fire stone,” as it sparks when struck together. Pyrite forms in many crystalline systems including cubic, pentagonal, dodecahedral, and octahedral. Found worldwide, major deposits of iron pyrite occur in Peru, USA, Spain, and Mexico. It is said to be an excellent shield against negative energy and pollutants.
