2.8" Heteromorph (Acrioceras) Ammonite - Russia

This is a beautiful, heteromorph ammonite fossil from the Agadir, Morocco. While most ammonites have spiral shells that retain the same shape throughout life, heteromorph ammonites have uncoiled shells. The likely had a different mode of life than other ammonites as the uncoiled shape would have slowed down swimming.

The ammonite is 2.8" long, and is well-prepared. The rock around it has been cut flat on multiple edges so that it displays in different orientations.
