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

The preparation was quite difficult, since the rock is very hard and shows very poor separation. Therefore the preparation took relatively long. The shell surface could only be preserved by time-consuming but gentle blasting.
