Description

Impressive specimen, prepared in an exceptional way. This type of preparation requires meticulous work of tens of hours. Of course, the horns 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. It is an authentic specimen of Museum Grade. Horns are prepared as free standing. The shell is in good condition, retaining some of the nodes on each axial ring.
