Description
A large free swimming Crotalocephalina gibbus Trilobite in excellent condition for sale.
The Trilobite from Morocco measures 3.3 inches or 8.4 cm and is well preserved and prepared. Initial crack is from the right cephalon (head) side to the the left side in the neck area of the thorax.
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 preparation even more efficient and qualitative upgraded.
Moroccan Trilobites 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 large free swimming Crotalocephalina gibbus Trilobite for sale here is one of those masterpieces.
