Description
Another well preserved Trilobite, a rare Ceratarges aries Trilobite from Morocco for sale. This specimen is about 2.2″ or 5,4cm from front of the head to the end of the tail spines. Ceratarges aries is the rarest species of the genus found at the Ceratarges beds of Jbel Zireg. It is characterised by the spine on the middle of the pygidium and the pushed up glabella with the two horns facing somewhat forward. Ceratarges aries accounts for only 5 % of the Ceratarges finds at the location.
There are a couple of glued cracks through the front of the Trilobite. These cracks are not avoidable. They occur, when quarry workers crack the rock in order to find fossils. Fossils don’t grow on rocks, they hide inside. Unfortunately in the layers of the hardy devonian rocks, fossils appear in all directions. Once the rock is broken, the fossil is discovered. Due to the nature of these rocks and the position of the fossil, the fossil is broken too. Experienced Preparators take on the task to glue them back together and to chisel or grind them out. In general cracks and some preparation marks are not avoidable and show that the fossil is real and not faked. There is no damage or replaced parts on this Trilobite.
The availability of pneumatic and air abrasive tools makes the work of the preparator even more efficient and qualitative upgraded. In some cases the use of Rewoquat(basically a laundry detergent) does a great job. The use of Rewoquat was discovered in Germany and is used in the preparation of calcidised fossils. Features of the eyes, the body-markings (pores etc.) and spines can be easier prepared out of the hardy rocks.
Trilobites like this Ceratarges aries Trilobite from Morocco for sale are often master pieces of preparation art. Mining of fossil and their preparation is a great source of income for the people, that live in the oasis of the Sahara desert. Whole villages depend on it. Some of the Trilobites processed take up to 100 hours of preparation. With an daily wage of 7 – 10$ Moroccan minimum wage, these prepared Trilobites are still affordable.
