Harpes Trilobite from the Devonian of Morocco

Description

Well preserved Harpes Trilobite from the Devonian of Morocco. The Trilobite measures about 4.4 cm or 1.6 inches. Preservation is good, lots of detail. There are some preparation marks on the front of the cephalon.

The initial crack just bypassed the cephalon. These cracks are not avoidable. Moroccan trilobites are mined. Unfortunately in the layers of the hardy Devonian rocks, fossils appear in all directions. Once the rock is broken in the mining process, 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 the pieces back together. then they chisel and grind them out. In general cracks and some preparation marks are not avoidable and show that the fossil is real and not faked.

The availability of pneumatic and air abrasive tools makes the work of the preparation even more efficient and qualitative upgraded. Hydrochloric acid or maybe Rewoquat can be used in some cases to soften the rock. Features of the eyes, the body markings (pores etc.) and spines can be easier prepared out of the hardy rocks.

Moroccan Trilobites like this Moroccan Trilobite Morocconites malladoides for sale here 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. The Harpes Trilobite fossil for sale here is about 4.4 cm or 1.6 inches long.
