This goniatite is probably a member of the Manticoceras genus. It comes from the Matagne formation of Belgium and is characterized by a extremely well preserved shell, showing fine ribs.

The preparation of this piece was relatively easy to do. Although the rock is very hard, the separation was mostly good, so that the preparation went quickly. However, caution is required if the shell shall be preserved. Working too roughly would cause the shell to chip off from the steinkern.

There is no glue or restoration of the weathered area.
