Ammonite in Pyrite Oval Cab.
Ammonite in Pyrite oval cab.
Lovely preservation of the fossil details. The pyrite picking out the shell walls of the creature and the creamy yellow calcite infilling the chambers.
The back is flat and unpolished, but with some dinks - please see photos. Some of the cutters dop also remains, please see pics.
10.9 x 19 x 4.3 mm.
