Here are two YouTube videos showing trilobite preparation back in 2005. It is neat to see this work as there are so many Moroccan fossils on the market. We see the finished product here in America but these videos show how some of the material is prepared. The first video shows a
Koneprusia brutoni Devonian trilobite from Oufaten, Alnif, Morocco being prepared through sand abrasion cleaning. That is one spiny trilobite!
The second shows a young man preparing a Devonian
Phacops rana trilobite with a hammer and nail.
