Description: This trilobite is a very beautiful and very well preserved proetid from the world famous locality of Jbel Gara el Zguilma, Morocco. The species Diademaproetus praecursor has a very characteristic tongue-like protrusion, which serves as a striking feature for identification. The trilobite was prepared in about 9 hours of painstaking detail work from the limestone and presents itself harmoniously on a natural matrix. Trilobites from this site are not easy to prepare because the shell can be very delicate. Without the necessary care, unsightly preparation marks and abraded shells are inevitable. For this reason, most of the trilobites offered for sale from this locality are more or less badly damaged. This piece was glued together from three parts at the beginning of the preparation (see photos of the state of the find). Afterwards, the trilobite was carefully uncovered under the microscope with the help of airscribes and fine blasting equipment. No restorations or reconstructions were carried out. Particularly noteworthy is the excellent preservation of the details of the shell, especially the fine tuberculations and the excellent preservation of the eyes.

As with all my fossils, this specimen comes with a signed certificate of authenticity.

The Locality: Jbel Gara el Zquilma has been an extremely well-known and thus classic site for the Devonian of Morocco for decades. The often excellent preservation of the trilobites with deep dark shells on light brown rock inspires trilobite collectors worldwide. Besides proetids such as Gerastos or Diademaproetus, phacopids such as Austerops or Morocops and the highly sought-after genera Koneprusia, Walliserops and Psychopyge are also found there (to name just a small selection).
