30300 - Well Prepared "Flying" 2.59 Inch Morocconites malladoides Middle Devonian Trilobite Hadrosaurus United States (6: AlaskaImpressive 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, the cephalic spine during the preparation process has been fractured and glued again, with slight restorations in the fracture zones. A preparation like this without small restorations is impossible. Morocconites sp, Boucot and McClure 1989 (trilobite) Trilobita Phacopida
