Koneprusia dahmani Trilobite

Description

Well preserved Koneprusia dahmani Trilobite for sale from Morocco. The Trilobite is about 1.7″ or 4.3 cm long. That includes the spines at the tail end.

The initial crack came through the very tail end.

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.

Moroccan Trilobites like this Koneprusia Trilobite 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.

Koneprusia is named after the village of Koneprusy in the Czech Republik, where it was first discovered.
