Ammonite

This pyritized ammonite shows a bite mark opposite the opening of the shell, at the end of the body chamber. This is, in fact, where muscles were located to hold the soft parts into the shell.

The bite marks are a paratype of Bicrescomanducator rolli. A paratype is an additional specimen that helps to define the variation in the fossil species.
