Description

Impressive specimen, prepared in an exceptional way. This trilobite has been prepared as free-standing. This type of preparation requires meticulous work of tens of hours. Of course, many of the spines during the preparation process have been fractured and glued again, with slight restorations in the fracture zones. A preparation like this without small restorations is impossible.
