1/2" Iridescent Hoploscaphites Ammonite - South Dakota

This is a small, iridescent .5" Hoploscaphities nicolletii ammonite specimen from the Fox Hills Formation of South Dakota.

These 70 million year old ammonites lived when South Dakota was a shallow inland sea. It was found preserved in a concretion that was split open. It then had to be hand prepared to remove the hard rock surrounding it from the shell, a very time consuming task.
