A pyritized ammonite specimen from Buttenheim, Germany, featuring two ammonites preserved together in matrix, with the original shell material naturally replaced by iron pyrite. The pyrite has a semi-lustrous finish, offering a nice balance of shine and natural texture. The two pieces were reassembled with a careful repair.

Highly sought after by collectors, this piece offers a genuine glimpse into prehistoric marine life and a unique cluster display for any collection.
