Ammonite, group of 5

This is an interesting group of colorful pyritized ammonites (Quenstedticeras sp.). The ammonites were collected from the Middle Jurassic age deposits along the banks of the Volga River near Saratov, Russia.

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.
