This trilobite is a large specimen of the relatively rare Nevadia weeksi from the Lower Cambrian of Nevada. It was lying nicely prone on 2 plates and the negative was still largely present. The first step was to bring the matrix into a harmonious shape and glue the two pieces together. The parts from the negative were then transferred.

The preparation was relatively difficult because the separation was not that good. Nevertheless, all parts of the trilobite could be uncovered in detail. Smaller restorations, especially along the break, were carried out sparingly and without excessive color adjustment. No color enhancer or other sealing was applied. This specimen is quite natural and authentic. A special feature is the Opistothorax, which is rarely preserved. This work was carried out for trifoss.com – here you will find authentic fossils of high quality.
