This specimen is a big asaphus from an old collection. The piece has a big imperfection in the area of the left librigena. The shell was roughly uncovered and covered in a very shiny varnish.
Initially the unsightly varnish was removed and the matrix smoothed. Covered pieces of the shell were thereby uncovered so the entire shell became visible. After the precision work, especially between the pleurae, the left side of the cephalon was reconstructed. After the successful rework, the piece is now finally worthy of being exhibited.
