Ammonite

Discoscaphites Gulosus

A exceptional, Discoscaphites gulosus ammonite specimen from the Fox Hills Formation of South Dakota. It's been wonderfully prepared nearly free from the hard concretion it was found in.

Ammonites were shelled cephalopods that died out about 66 million years ago.

Ammonites were born with tiny shells and, as they grew, they built new chambers onto it.

They would move their entire body into a new chamber and seal off their old and now too-small living quarters with walls known as septa.
