This Ammonite fossil, a coiled nautiloid, shallow sea water creature, fossilized by pyrite, most likely lived in the geologic Jurassic period, about 145 to 199 million years ago. Often worn for educational or scientific interest, and as a conversation piece, it is, nevertheless, a beautiful stone of segmented light gold with gray to charcoal coloration. This stone fossil can be worn with anything, but is probably most appropriately worn with earth tones, or clothing designed for natural world interest.
