Cretaceous Ammonite:

Polyptychoceras

 

 

Photo 1: Polyptychoceras in concretion.

This heteromorph ammonite is quite common in Cretaceous shales on the Trent and Puntledge Rivers. They are known to collectors as the paper-clip ammonites or sometime they are referred to as candy canes.

In this sample, fossilized remnants of the shell are still visible over most of the ammonite. These ammonites have 3 parallel shafts, but usually only two are found --one bend in the paper clip.
