Ammonites were predatory cephalopod mollusks that resembled squids with spiral shells. They are more closely related to living octopuses, though their shells resemble that of nautilus species. True ammonites appeared in the fossil record about 240 million years ago during the Triassic Period. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
Covered in a Mother of Pearl nacreous shell, the Ammonite’s opalescence is due to the Aragonite found in the shell. As light travels and bounces through the layers of Aragonite, a rainbow spectrum can be observed. Thicker layers of Aragonite can lead to deep shades of red and orange, while thin layers can display shimmering greens and dainty violets.
