Fissilobiceras sp. (Buckman 1919)
I prepped this ammonite with a diameter of 50cm. for a customer who allowed me to show it here. I had to glue the living chamber back on which was in 2 pieces and also fill a lot of gaps with modelling clay. His wife did a great job at balancing the colors with water paints. This is quite a rare find, particularly at this size.
