Time Period: Cambrian (Approximately 400 Million years Old)
These primitive cephalopods are approximately 400 million years old and are related to the modern squid or octopus. They are similar to ammonites, but have a straight shell rather than a coiled shell. These fossils from Morocco exist as white fossils in a dark gray or black marble matrix.
As each is a natural fossil each one is unique. There will be variations in the coloring and size from piece to piece. No two will be alike!
