Description: This trilobite is a very nice and very well preserved phacopid from the world famous locality “Red Cliff” Hamar Laghdad near Erfoud, Morocco. Probably a juvenile stage of Morocops granulops (?), but it is also quite possible that it is a yet undescribed species. In contrast to M. granulops the tubercles are less pronounced. The trilobite was prepared in about 9 hours of painstaking detail work from the limestone and presents itself harmoniously on natural matrix. Trilobites from this locality are not easy to prepare, because the shell is very delicate and the rock sticks strongly to the shell. Without the necessary care, ugly prep marks and abraded shell are inevitable. For this reason most of the trilobites offered for sale from this locality are more or less damaged. This piece was glued together from three parts at the beginning of the preparation (see photo of the find condition). Afterwards a detailed and gentle exposure under the microscope was done with the help of compressed air technique and fine blasting equipment. Apart from filling a gap between the sections (see photos), no restorations or reconstructions were made.  Particularly noteworthy is the excellent detail preservation of the shell, especially the fine tuberculation and the eyes: the single lenses are wonderfully preserved and show impressively the typical greenish coloration.

As with all my fossils, this specimen is accompanied by a signed certificate of authenticity. 

The site: “Red Cliff” at Hamar Laghdad near Erfoud is world famous for its “Red Fauna”. Like the trilobites, the rock is reddish in color due to high concentrations of iron compounds. The shell of the trilobites is permeated by fine pores, through which the process of silification and thus coloration can take place. However, the eyes of the phacopids of this locality are sometimes clearly green colored. The unicellular lenses of the trilobites are made of calcite, have a high magnesium level and no pore channels. This beautiful coloration of the shell makes the “Red Fauna” a unique group of fossils, which clearly stand out among the common trilobites.

The site has been considered played out for several years, so no further finds are expected.
