Trilobite Zlichovaspis rugosa for sale

Description

This large Moroccan Trilobite Zlichovaspis rugosa, with characteristic pustules is 12 cm or 4.7 inches long. Both eyes show lenses. The fossil has a initial crack going through the left side of the fossil. 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. Some preparation marks show on the head and the left eye.

There are many Odontochile and Zlichovaspis Trilobites posted and printed in books. Odontochile occurs in the lower parts of the Prag Formation, while the Trilobite Zlichovaspis rugosa follows above and continuous into the Ems or  Zlichov Formation. The Zlichov Formation is named after the village of Zlichov near Prag in the Czech Republik.
