About the preparation -  This group of trilobites were German directed to ensure that there was no restoration or colorization. So, everything is natural. The best Moroccan preparators are very good and have proper tools and techniques. You will see the faint cracks in the matrix that exposed the trilobite. You may see faint cracks in the of the trilobite shell which were also how the trilobite was exposed. You will see natural pathologies or flaws prior to fossilization. And you may see some minor damage that occurred while digging or preparation. Nothing is covered up in this group, but the flaws are so small and minor that is does not take away from overall aesthetics of the trilobite. Many preparators will cover up these flaws with putty and paint. These trilobites are natural and highly attractive without restoration.
